Halo: The Master Chief Collection 100% guide

Create any custom game variant and save it with the name .fortune. The achievement unlocks when the variant is saved under that name. Halopedia notes that other saved names (map variants, loadouts, and similar) also trigger it, but the custom game variant is the standard method.

Save five custom game variants in the custom games lobby. Changing one setting and saving under a new name is enough each time. The .fortune variant above counts as one of the five. The achievement unlocks when the fifth variant is saved.

Open Forge in any game, place or move one object, and save the map variant. Repeat until you have saved five map variants. The achievement unlocks when the fifth is saved. If you save one of them in Halo: Reach on Forge World, you also earn Capacious Cartography (covered in the Halo: Reach multiplayer section).

Complete any campaign mission or multiplayer match. It unlocks on your first completion, so it will come with the first mission you finish in this guide.

Play any multiplayer or co-op game at least three months after your first MCC game. You cannot speed this up. Note the date you started, and make sure you play an online co-op mission or a multiplayer game after the three-month mark. The guide's matchmaking phase will cover it naturally, but put a reminder in your calendar.

Start any Halo: Combat Evolved Anniversary mission or match on the 15th of any month.

Start any Halo 2 Anniversary game on the 9th of any month.

Start any Halo 3: ODST game on the 22nd of any month.

Start any Halo 3 mission or match on the 25th of any month.

Start any Halo: Reach game on the 14th of any month.

Start any Halo 4 game (campaign, Spartan Ops, or multiplayer) on the 6th of any month.

Kill 100 enemies or players in any mode. This unlocks early in your first campaign.

Kill 5,000 enemies or players. Expect this to unlock partway through the campaigns.

Kill 20,000 enemies or players. Campaign kills, Firefight kills, and multiplayer kills all count. Most players finish this with custom Firefight after the campaigns.

Complete 10 missions or multiplayer games. Every campaign mission and every finished multiplayer game counts, solo or co-op, and so do missions finished inside playlists.

Collect 500 campaign or playlist medals. Medals earned in campaign missions and campaign playlists count, regardless of whether medals display on your screen. Custom games do not count. In split-screen, only the main signed-in player earns medals toward this track, so play your campaigns on your own profile as player one. Turning on the scoring HUD makes it easier to see what you are earning.

Kill 100 Grunts. All species-kill achievements count kills across every game, in campaign on any difficulty and in Firefight, including custom Firefight. Kills are not removed when you die or revert a checkpoint, so you can re-kill the same group after reloading. This unlocks naturally in the first few missions.

Kill 100 Elites. This comes naturally in Halo: Reach and Halo: Combat Evolved.

Kill 100 Jackals. This comes naturally during the early campaigns.

Kill 100 Brutes. Brutes appear in Halo: Reach, Halo 2, Halo 3: ODST, and Halo 3. This will unlock during whichever of those you play first.

Kill 50 Hunters. Hunters are rare in normal play, so this will probably still be in progress after the campaigns. The final cleanup section covers a custom Firefight farm.

Kill 100 Flood. The Flood appear in Halo: Combat Evolved, Halo 2, and Halo 3 campaigns, and in Halo 3: ODST custom Firefight with Flood waves, so this unlocks naturally.

Kill 100 Watchers. Watchers, Knights, and Crawlers exist only in Halo 4 and its Spartan Ops. These three progress during the Halo 4 section.

Kill 100 Knights. Halo 4 only.

Kill 100 Crawlers. Halo 4 only. This usually unlocks during the Halo 4 campaign.

Aim down the sights (zoom) with an MA37 assault rifle, M319 grenade launcher, or M45 shotgun. A small binary signature appears in the scope overlay and the achievement unlocks. It works on any mission, difficulty, or mode, so do it in the first minute of Winter Contingency.

On Legendary only, a cloaked Spec Ops Elite spawns near the distress-beacon site at the start of the mission, carrying Data Pad 10, and flees downhill along the lower path toward a gate, away from your first objective. Sprint down the hill immediately and hit it before it reaches the gate; when tagged, it pauses and looks at you, which gives you time to strip its shields and kill it. Emptying the magnum into it and finishing it with the assault rifle works well, and accurate fire matters, because wasted ammo is the usual reason the chase fails. If it gets past the gate, it keeps running but can still be killed. The achievement unlocks when you kill the carrier. If it is genuinely lost, restart the mission on Legendary; it is not documented whether reverting to a checkpoint brings it back. A co-op partner makes the chase easier on a separate Legendary run, but your solo Legendary run is the one that counts for A Monument To All Your Sins.

Walk over Data Pad 10, dropped by the Elite you just killed. This requires Legendary.

Kill seven Moa, the flightless birds that wander the opening farmland. You must get all seven in the same run; reverting to a checkpoint before the seventh kill resets the count. Shoot them from range as soon as you see them, then continue.

Data Pad 1 works on any difficulty. Take the flatbed truck to the bridge, then keep left after it until you reach a small cluster of homestead buildings that Jun flags with "Heat sigs in the structure ahead." The pad lies beside a group of dead civilians in the circular building at the south end of that cluster, the structure on the right as you arrive. It unlocks when you pick it up.

Kill a gold Ranger Commander Elite named Bob. These rare Elites can appear on several missions, but a known spot is on Winter Contingency on Heroic or Legendary, near the Bravo area past the waterfall. Bob tends to flee, so kill him quickly. If he does not appear, it is not worth restarting the mission. Keep an eye out on other missions instead.

Finish Winter Contingency without entering any drivable vehicle. It only counts on Normal or higher, so do it on the Legendary run by walking every vehicle section, or on a separate Normal run if you would rather drive on Legendary. It unlocks once you clear the landing zone for the Falcon, before the mission ends. Avoid the Warthog passenger and gunner seats as well. In co-op, if any player enters a vehicle, nobody earns it.

Complete Winter Contingency on any difficulty. It unlocks at the end of your first run.

Beat the 15:00 par time on Winter Contingency. Play on Easy, skip cutscenes, and drive between objectives. If you skipped the vehicles on your Legendary run, remember that this run can use them.

Beat the 15,000 par score on Winter Contingency with scoring turned on.

Data Pad 2 works on any difficulty. Inside the ONI facility's atrium (the area that becomes the Sword Base multiplayer map), climb the ramps; the pad is under the topmost staircase, at the spot that becomes the multiplayer shotgun spawn. Sources count this floor differently (second floor of the atrium, or the fourth floor under the stairs to the fifth), but it is the only any-difficulty pad on this mission.

On Legendary, Data Pad 11 is at Farragut Station. At the building with the comms-relay switch, a broken wooden extension at the back reaches toward the neighbouring cliff. Sprint-jump the gap in the wooden bridge (a grenade jump also works), then follow the rocks to the right to the pad.

Use the Target Locator to destroy two vehicles with one strike. After exiting the ONI building, wait until the two Wraiths sit close together, then call the strike between them. Alternatively, a Phantom drops two Ghosts at Airview Base that can be hit with one strike. One TrueAchievements report flags this as buggy and recommends Normal, where the vehicles are less likely to move apart; if it fails on Legendary, try a separate Normal run.

This needs two players. Hidden switches sit on rocks by the water and on a cliff ledge overlooking the base. Both players press their switch at the same time; the objective changes to Reach Racer and the achievement unlocks. Do this with any co-op partner. It does not need Legendary.

Complete ONI: Sword Base on any difficulty.

Beat the 10:00 par time on ONI: Sword Base on Easy.

Beat the 25,000 par score on ONI: Sword Base with scoring turned on.

Data Pad 3 works on any difficulty. Right at the start, follow the right-hand canyon wall to a side path into a small cave. The pad lies against the cave's left wall, between rocks and shrubs. It is easy to walk past, so check before moving on.

On Legendary, play on until the Reach militia troopers are fighting the Covenant, then continue into the valley. Jump onto the rocks on the right of the valley entrance and hop along them, crossing a large gap with a Sprint jump. Data Pad 12 is on an outcrop on the right side of the valley just before the rock bridge where Jun and the troopers take cover from the Phantom. On the way back you can drop down to the stone bridge. Two alternative routes reach the same spot from below: follow the riverbed past the dam to a stone arch and climb it using a branch, or crouch-jump over the dam and across rock formations to a slanted wall. You do not need a jetpack.

Complete Nightfall on any difficulty.

Beat the 10:00 par time on Nightfall. This par is tight. Play on Easy, avoid fights, and use the forklift skip if you are short on time: when you reach the locked Stealth Pylon gate, park the forklift against the gate, exit through the gate, then sprint through the now-empty remaining section to the end of the mission.

Beat the 7,500 par score on Nightfall with scoring turned on.

Zoom in on the large orange BXR mining company logo near the stairs before the second flight of stairs. Any scoped weapon works. The achievement unlocks when you view the logo.

An Elite Zealot shows up as a red marker on a distant rooftop and flees after a short time. Snipe it before it escapes; the Needle Rifle is the usual recommendation. TrueAchievements flags this one as buggy, so if it does not unlock, try again on Easy, where the Zealot dies faster.

Data Pad 4 works on any difficulty. Inside the BXR mining facility, below the area where you are told to kill the Zealot, climb the western roof and drop through the hole near a red vat into the room with the Plasma Launcher and two health packs. Behind three UNSC crates on the opposite side of that room, the pad is on the second shelf of a rack.

On Legendary, at the second anti-aircraft cannon area, jump onto the broken concrete columns of the destroyed overpass (from a vehicle if needed) to reach the stranded deck. Data Pad 13 lies there beside a damaged Warthog and dead Army troopers.

Complete Tip of the Spear on any difficulty.

Beat the 15:00 par time on Tip of the Spear on Easy. This was the most-reported failed unlock at Reach's launch. If it does not unlock on a clearly sub-par run, replay the mission rather than assuming you missed it.

Beat the 30,000 par score on Tip of the Spear with scoring turned on.

Data Pad 5 works on any difficulty. In the Sabre launch facility's control room with the Corvette hologram, go up the left elevated area, lit red and orange. The pad is in front of the control desk beside a body.

Use a Pelican's turret. In the hangar area, crouch at the Pelican's nose and hold the interact button until you enter the turret. The achievement unlocks when you are in the gun.

On Legendary, in the hangar holding the Sabre and before you board it: just before the yellow-outlined stairs, look left for a platform and jump onto it. Climb the grey scaffolding onto the grey diagonal pillar and follow it to the end, where Data Pad 14 lies. Precise crouch-jumps help.

In the space section, destroy the Corvette's engines and its escort of Seraph fighters and Banshees within three minutes. This only counts on Heroic or Legendary, so do it on your solo Legendary run, or on a separate Heroic or co-op run if it fails. Reverting to a checkpoint resets the timer. Take out the engines first, then the Seraphs, then the Banshees.

Complete Long Night of Solace on any difficulty.

Beat the 25:00 par time on Long Night of Solace on Easy.

Beat the 45,000 par score on Long Night of Solace with scoring turned on.

View the World Cuisine advertisement for Moa burgers. It is in the chapter The Devil His Due, after you first meet civilians and before you take the elevator to Traxus Tower. Zoom in on the advertisement until the achievement unlocks.

Data Pad 6 works on any difficulty but needs the jetpack. After you take the jetpack and fly across the large area, you land in a combat zone. Before entering the building you are told to fly to the top of, look for the construction platform above its doorway; the pad is on that platform's dim catwalk beside a body.

On Legendary, in the large plaza across from Traxus Tower, pipes lead to zig-zagging struts directly across from the executive landing pad. Fly to the struts from the east side of the plaza (from the landing pad you can only nearly reach them), climb beam by beam with the jetpack to the pair of vent units at the top, and land on top of the right-hand vent for Data Pad 15. Landing on the vent takes patience.

From the anti-aircraft battery location near the end of the mission, travel out of bounds back to the area where you defended Army troopers from Brutes during the Falcon gunner section; the hidden Marines are along that route, by the cliffs of the horseshoe-shaped bay. Jetpack parkour works, but the Acrophobia skull lets you simply fly there. The achievement unlocks when you encounter them.

Finish Exodus without using any armor ability. In Reach, sprint is an armor ability, so avoid sprint too. The jetpack section is the obstacle. The easiest method is co-op: your partner plays normally while you stay away from every armor ability and respawn on them past the jetpack sections. Solo players use gravity hammer jumps to cross. Do this on its own run, not your Legendary run.

Because this run forbids the jetpack, it cannot collect Data Pads 6 or 15; get those on another run.

Complete Exodus on any difficulty.

Beat the 20:00 par time on Exodus on Easy.

Beat the 30,000 par score on Exodus with scoring turned on.

Do this first, in the Falcon you start with. On Legendary, Data Pad 16 is on the skyscraper directly behind the starting landing pad (to the south). Fly down its side until the HUD warns you to pull up, at around -100 to -125 on the altimeter. The pad is on a narrow ledge in the inset section, on the left at the end of the rail. Nose the Falcon onto the ledge and climb out without falling. If you lose the Falcon or fall, restart the mission.

Look for the grisly scene of bodies near the start of New Alexandria. It unlocks when you observe it.

Enter Club Errera. The achievement is reported to unlock when you go inside.

Hit the green switch on a lower ledge under the hospital landing pad, then return to Club Errera to find the Brute DJ. It unlocks when you party with him.

Hit the green switch under the air-conditioning vents on the club roof, then return to the dance floor and listen. It unlocks when the hidden music cue plays.

Data Pad 7 works on any difficulty but needs a Falcon. Seven buildings ring the Olympic Tower (ONI headquarters); six have flat roofs with Shade turrets, and the seventh, northwest of the tower, has a large wedge shape covering most of its roof. Land the Falcon on that roof: the pad is on the north side, the side with five vent units, next to a door.

Buck radios in asking for a Falcon escort. That side objective is randomized, so it does not appear on every run. Larger co-op groups get more side objectives per cycle. If it does not appear, replay New Alexandria; the Easy and scoring runs give you more chances.

Destroy three of the anti-aircraft batteries. This normally happens during the final objective.

Fly both the Pelican and the Phantom. Near the end, a jetpack user hits the green ceiling switch to the left of Club Errera, then flies through the ring-shaped building opening. TrueAchievements lists this as co-op, and it was among the launch-era unlock failure reports. Do it with a partner on any difficulty.

Complete New Alexandria on any difficulty.

Beat the 20:00 par time on New Alexandria on Easy.

Beat the 20,000 par score on New Alexandria with scoring turned on.

Data Pad 8 works on any difficulty. Inside Sword Base, in the red-lit main atrium with cloaked Spec Ops Elites, the pad is on the floor immediately left of the door control that your squad activates. Pick it up before you press the switch, because the switch triggers a cutscene.

On Legendary, take a jetpack outside Dr. Halsey's lab (the jetpacks stand along the wall and are not highlighted). Fly southeast from the Wolf Spider turret marked C toward a cliff face. On its right side, a small rock ledge under the bridge holds Data Pad 17. Start with a full charge and feather the jetpack in short bursts to cross the gap.

Finish The Package on Legendary with your Scorpion still intact. The achievement checks when you reach the Enter Sword Base objective. Snipe the anti-aircraft guns and Shades from range, and pull back to safety whenever the Scorpion starts smoking. This is part of the Legendary run, but restart the mission if the tank is destroyed.

Hijack any Banshee in the Reach campaign. The most reliable method is on The Package at Rally Point Bravo: disable a Banshee with an EMP (an overcharged plasma pistol shot) and hijack it while it is incapacitated. Jetpack-jumping onto a passing Banshee from the hospital roof on New Alexandria is an alternative.

This needs two players. Get a Ghost and push the wooden crate at the dock. One player drops into the water (a 10-second timer starts) and hits the green switch at the base of the rocks. The partner then hits the second switch that briefly appears on the wooden wall. Four Banshees spawn on the starting building and the achievement unlocks.

After defending Halsey's building, jetpack to the far platform and hover-press the hidden switch. Kill the sword-wielding Elites that appear, then enter Halsey's lab. The achievement unlocks when you get inside. No difficulty requirement is confirmed.

Complete The Package on any difficulty.

Beat the 20:00 par time on The Package on Easy.

Beat the 65,000 par score on The Package with scoring turned on. This is the highest Reach par score, so use your best skull setup.

On Legendary, Data Pad 18 is in the shipbreaking yard that becomes the multiplayer map Boneyard (Rally Point Alpha), on the roof of the garage building where the Scorpion spawns in Invasion. Cross the walkway over the battlefield, go up the ramp, and jump through the gap in the steel-beam barrier on the right (or off a jumpable barrier) onto the rooftop. The pad is around its south corner. Sprint jumps make it easier.

Data Pad 9 works on any difficulty. After the Boneyard area, head back inside. Past two dead troopers in a corridor, keep right to find two windows looking into two rooms. Break the window of the second room and crouch-jump in. The pad is in the far-left corner, on a table and a pile of cardboard boxes.

In the final cutscene, during the shuttle docking flyby, hold right on the D-pad or look right to see John-117 in cryo. The achievement unlocks when you spot him.

Complete The Pillar of Autumn on any difficulty.

Beat the 20:00 par time on The Pillar of Autumn on Easy.

Beat the 25,000 par score on The Pillar of Autumn with scoring turned on.

On Legendary, to the right of the start a ramp leads up beside a large pipe, where a dead Spartan and a sniper rifle lie on metal planks. Data Pad 19 is inside the pipe behind a metal fence, and it can still be picked up. Grab it right away, before the waves build up.

Complete any Legendary mission with three or more skulls enabled and campaign scoring on. Cowbell, Grunt Birthday Party, and IWHBYD do not count toward the three. Lone Wolf is the shortest way to do it, because it counts as complete when you die: start Legendary Lone Wolf with scoring on and three qualifying skulls (for example Catch, Famine, and Thunderstorm), grab Data Pad 19, and fight until you fall.

Reach 30,000 points on Lone Wolf. This will come with One Final Firefight.

Reach 150,000 points on Lone Wolf. Use Easy with campaign scoring on and as many skulls as possible except Blind, Cowbell, and Mythic. Stay under the turrets so only a few enemies engage at once, chain assassinations, and use the sword or plasma pistol. Expect an hour or more. Both score achievements unlock as your score passes the thresholds and is banked at the end.

Complete every Reach level on Easy or higher. This unlocks with your Legendary sweep.

Complete every Reach level on Normal or higher. This unlocks with your Legendary sweep.

Complete every Reach level on Heroic or higher. This unlocks with your Legendary sweep.

Complete every Reach level on Legendary. Co-op is allowed for this one, but your solo run covers it.

Complete every Reach level on Legendary by yourself. Include Lone Wolf, which counts as complete when you die. This is the reason the route plays Reach solo on Legendary.

Complete all Reach Legendary missions in under three hours total. The total is your best Legendary time on each mission added together, solo or co-op, so you only need to improve your slowest missions. Check your best times in the Career menu. The par times add up to 2:35, so hitting par on Legendary leaves a buffer. Co-op speedruns and the known Nightfall skip help.

Beat par time on all nine Reach story missions. It unlocks after the ninth par time.

Beat par score on all nine Reach story missions. It unlocks after the ninth par score.

Collect all 19 data pads. Each pad's achievement unlocks when you pick it up, and the per-pad achievements are your tracker; the game has no in-world marker for them. If you are missing one, replay its mission on a difficulty that spawns it (Legendary for pads 10 to 19) and pick it up again. The full list is in the Collectibles section at the end of this guide.

Kill 100 Skirmishers. These fast Jackal-like enemies appear throughout the Reach campaign and in Reach Firefight. This should unlock naturally during the campaign.

Kill 1,000 Skirmishers. You will be short after the campaign. Finish it in a solo custom Firefight with Skirmisher-heavy waves, which also helps your other kill counters.

Complete any one Halo: Reach playlist.

Complete three Halo: Reach playlists. Use three different short playlists. The LASO playlist also counts if you finish it first.

Complete the Halo: Reach LASO Campaign playlist: every Reach mission on Legendary with the playlist's forced skull set, including Iron and Black Eye. Co-op is allowed, and progress saves between missions. Bring the best partners you can, play carefully, and use the save-and-quit menu before a death would cost you a long stretch. This is the hardest achievement in the Reach list.

Complete one Firefight set on Normal or higher. A solo custom Firefight works.

Splatter an enemy with a forklift. The easiest method is a custom Firefight on Courtyard with the Gruntpocalypse setting and a starting Gravity Hammer. Hit the forklift with the hammer so it slides into Grunts.

Listen to the hidden UNSC radio chatter on a Firefight or multiplayer map. Campaign radios do not count. The easiest spot is a solo custom Firefight on Overlook: go to the upper floor at the back of the main base and stand by the radio until it plays.

Load a solo custom game on Boardwalk and stand at the "Make Out Point" callout location until the humorous callout shows on your HUD.

Open Forge, select Forge World, and save any map variant. If you did this during First Session Setup, it is already done.

Complete 10 assassinations on enemy players. Custom games count. Start a custom Slayer game with a split-screen guest or a friend on the enemy team and assassinate them from behind 10 times.

Headshot 10 enemy players while they are sprinting (Headcase medals). Custom games count. Use a SWAT-style custom game with a second player who sprints back and forth while you take headshots.

Kill 10 enemies while using a jetpack. Current achievement guidance documents both custom games and Firefight as working, so no matchmaking is needed. The easiest method is a solo custom Firefight with a jetpack loadout: hover with the jetpack active and kill 10 enemies while airborne. A custom game against your second player with jetpack loadouts also works.

Earn a Skullamanjaro medal in a matchmade Headhunter game by personally banking 10 skulls at once. Since the 2023 matchmaking changes, Team Headhunter no longer produces the medal, so use the 8-player free-for-all route: choose the 8-player FFA option, select Halo: Reach, then Asset Denial, and Headhunter. Collect 10 skulls without dying and bank them all in one deposit. Because the playlist is quiet, the practical method is boosting: two parties of four players (or four controllers each) search at the same time so they match into the same lobby, then take turns feeding skulls to one player. This must be matchmaking, and there are documented unlocks in 2026.

Win a matchmade game of Invasion as the defenders during the first phase. Invasion lives in the ranked/competitive category, and players have called it a dead playlist since 2023. Organized boosting is the realistic route: as of 2025, groups such as the Halo Syndicate Discord ran scheduled Saturday sessions for Invasion. Coordinate a full lobby, defend the first phase for the full timer, and the achievement unlocks on the win. One player warned that organized boosting could risk penalties, so use your judgment. This is the achievement most at risk if Reach population drops further, so do it early.

Right after the cryo tutorial, check the back of the cryo deck behind the stacked crates. The achievement unlocks when you pick up the skull.

Fight alongside the Marine Chips Dubbo while he talks. His escort to the bridge does not count; it unlocks once you are in combat with him and his line plays. This normally happens without trying.

Terminal 1 is a console on the left side of the Autumn's bridge with a flashing red "INCOMING MESSAGE". Activate it before you leave the bridge area. This terminal is often missed because it is so early.

Complete The Pillar of Autumn on Legendary without picking up an overshield. Do this on your Legendary run alongside Walk It Off.

Complete The Pillar of Autumn on Legendary without picking up a health kit. Health kits usually sit on the right side of doorways, so hug the left. Dying does not void it, but a checkpoint revert after picking up a kit does not undo the pickup; restart the mission if you grab one.

Complete The Pillar of Autumn on any difficulty.

This is a Legendary Easter egg. Do it on a separate Legendary run so it does not interfere with Walk It Off. After cryo, crouch-jump onto the yellow canister behind you and drop back down. Go to the bridge and trigger the Keyes cutscene, collect the pistol and an assault rifle, and return to the bridge. Kill Keyes and the bridge crew; invincible Marines spawn from a locked door. When Cortana says the Master Chief has gone rampant, a second door unlocks. Hold the Marines back, rush through that second door, and look up at the ceiling with your flashlight for the blood heart. The achievement unlocks when you view it. These steps come from the original game's Easter egg; whether MCC also requires classic or remastered graphics is not documented, so try remastered first and repeat in classic if it does not unlock.

Complete any CE level without jumping. The Pillar of Autumn is the recommended level: walk into the sloped pipes instead of jumping over them. 343 Guilty Spark cannot be done because it has mandatory jumps. On PC, the cutscene-skip key counts as a jump, and Xbox behavior is not documented, so do this on a run where you do not skip cutscenes, such as your scoring run, unless you are sure your skip button is not your jump button.

Beat the 15:00 par time on The Pillar of Autumn. Easy is fine.

Beat the 17,000 par score on The Pillar of Autumn. Use Legendary with Boom and Piñata, and melee Elites in the dining hall for extra plasma grenades.

Complete any level on Heroic or higher without taking health damage. Shield damage is fine. A short level such as The Pillar of Autumn on Heroic is the easiest choice. Revert to the last checkpoint whenever your health is hit. You can do this on any CE mission, so if your Legendary run of a short level goes cleanly, it may unlock there.

At the start of the level, near the waterfall, the skull is behind the large boulder on the right in the water.

Personally destroy three of the four Banshees on Halo in one playthrough. Kills by your Warthog gunner do not count. Two Banshees attack right at the start: damage both with the pistol until they smoke and finish them before they fly away, then get one more later.

Above the entrance to the underground facility, look up for pipes. Walk along the cliff edge and jump onto the pipe mesh to reach the skull.

Terminal 2 is in a small alcove off the main underground tunnel route. Drive past the jump to the far end of the alcove.

Launch a Warthog so it stays in the air for at least five seconds and splatters an enemy before landing, without the driver being thrown out. The most reliable method is using a Ghost as a ramp and adding a grenade under the Warthog. It works on any level with Warthogs; Halo is the first good opportunity.

Complete Halo without entering any vehicle. Grenade-jump the large gap near the start of the underground tunnel section, or turn on the Acrophobia skull. This adds 20 to 30 minutes, so do it on a separate Easy run rather than your Legendary run.

Complete Halo on any difficulty.

Beat the 20:00 par time on Halo. Drive between rescue sites and do not wait for every Marine group.

Beat the 12,000 par score on Halo.

Kill the first group of enemies (Grunts, Jackals, and one Elite) without being detected. Easy makes one-shot sniper kills possible. Stay behind the rocks and do not lean out. Classic graphics make enemies easier to see in the dark, but toggle back before collecting anything.

Kill a Hunter with a single pistol round. Shoot the orange flesh exposed on its back or neck. The first Hunters appear on this mission and on The Silent Cartographer. Easy makes the shot more forgiving.

The skull is in the bottom-floor hallway that the Hunters exit from into the hangar.

Terminal 3 is on the ship's bridge, in the middle of the front holographic displays, in a section marked in red.

Complete The Truth and Reconciliation with at least four rounds left in your sniper rifle. Keep the sniper rifle all mission and refill from the ammo caches in the brig area and outside the bridge. The Bandanna skull (infinite ammo) removes the problem entirely.

Complete The Truth and Reconciliation on any difficulty.

Beat the 20:00 par time on The Truth and Reconciliation.

Beat the 19,000 par score on The Truth and Reconciliation.

Clear the opening beach landing on Heroic or Legendary with no Marine deaths. Push ahead of the Marines to draw fire, grenade enemies behind cover, and keep Marines away from Elites with plasma grenades. Revert the checkpoint if a Marine dies.

The skull sits on a hilltop between three bushes.

Terminal 4 is against the structure with the Marathon symbol near the middle of the island, where the first pair of Hunters appears, beneath the bridge.

At the end of the tunnel, the skull is on the ceiling of the security console chamber. Reach it with a grenade or rocket jump. In co-op, one player can crouch on the window strip in the tunnel below while the other respawns on top of them to grab it.

Complete The Silent Cartographer without shooting, throwing grenades, meleeing, dying, or restarting. Play on Easy and do this on its own run. Halopedia says both players must obey the restrictions in co-op, so do it solo.

Complete The Silent Cartographer on any difficulty.

Beat the 15:00 par time on The Silent Cartographer.

Beat the 18,000 par score on The Silent Cartographer.

The skull is on a pipe protruding from the gorge walls.

The skull is on a raised platform in the middle of a fog-filled room.

Destroy four Wraiths with the Scorpion. Run past the first Wraith to get the Scorpion, then kill the Wraiths along the route. The last one is on the frozen lake before the Marine group.

Terminal 5 is at the bottom of a pit in front of the Control Room structure, under a diagonal strut.

At the end of the level, take a Banshee to the tower above the Control Room entrance. Land on the second of the three brackets, face the cliff, and move right to the end of the bracket just before it slopes down. The achievement unlocks when the hidden music cue plays.

Complete Assault on the Control Room on any difficulty.

Beat the 15:00 par time on Assault on the Control Room. Use the corner-ride trick down the canyon walls at the first bridge, or hijack the Banshee at the first bridge, which only appears on Heroic and Legendary.

Beat the 18,000 par score on Assault on the Control Room.

At the very start, while you are still in the Pelican, throw a frag grenade out of it. You stay aboard as it flies off, and the achievement unlocks after a few seconds.

The skull is in a small drop behind the Shade turret on the left side of the facility.

Terminal 6 is above a doorway that you pass while riding the third elevator. You get only one jump attempt per run, so look for the doorway as the lift descends and jump into it. If you miss, restart the mission.

Complete 343 Guilty Spark on any difficulty.

Beat the 15:00 par time on 343 Guilty Spark.

Beat the 17,000 par score on 343 Guilty Spark.

The skull is at the back of a vent shortly before the Index chamber. A grenade jump gets you in.

Terminal 7 is on the third floor, opposite the Index chamber. Jump the low barriers across the chasm to reach the flashing yellow panel.

The skull sits on the ground right behind the Index on the final platform.

Complete The Library on Heroic or Legendary without dying. Checkpoint reverts do not count as deaths, so revert whenever things go wrong. The Bandanna skull helps; carry the pistol and shotgun and run past spawns at the elevators.

Complete The Library on any difficulty.

Beat the 25:00 par time on The Library.

Beat the 25,000 par score on The Library. Use Legendary with Catch, Thunderstorm, Piñata, and Boom, avoid deaths, and stay away from carrier forms.

Terminal 8 is in the opening control room, across from the central console.

After the final Wraith fight, take a Banshee to the top of the underground entrance to find the skull.

Complete Two Betrayals on Legendary without killing any Grunts. In MCC this needs Legendary. The co-op cheese: your partner does all the fighting, including every Grunt kill, while you stay out of the way and respawn on them. The player who never kills a Grunt earns it.

Complete Two Betrayals on Legendary without picking up a new weapon. The same co-op method earns both on one run. Solo players should use the Bandanna skull so they never need to change weapons.

Complete Two Betrayals on any difficulty.

Beat the 20:00 par time on Two Betrayals.

Beat the 16,000 par score on Two Betrayals.

On the Truth and Reconciliation's bridge, look at Keyes' pipe hanging from a tendril attached to him on the central platform.

After the Keyes scene, Terminal 9 is in the sunken crevice beside the raised platform, on the red panel on the right wall of the crevice.

Kill every Elite on Keyes on Heroic or Legendary. Halopedia estimates around 30 to 35 Elites, but treat that as approximate. Easy-to-miss Elites fall into the coolant pools below, man the Shade turrets, or sit on second floors. Check below before moving on each time. This is not compatible with the skip used for the par time, so do it on your Legendary run.

Complete Keyes on any difficulty.

Beat the 15:00 par time on Keyes. The standard route uses a Flood bump or a shield bump past the first wall to reach the bridge early.

Beat the 20,000 par score on Keyes.

Terminal 10 is a wall-mounted screen on the second floor of the cryo bay, where Sentinels fight the Flood.

During the Warthog run, the skull is on the railing or beam where Foehammer goes down.

On the Warthog run after the bridge where Foehammer is shot down, keep right to a small side tunnel. Use the first (right) entrance or the Grunt will not spawn. Listen until he finishes his line.

At the big Warthog jump with the free fall, drive to the right so you land on the side of the floating platform. Enter the corridor and look right to see "Rex" written in blood.

Finish the Warthog run without being forcibly ejected from your vehicle. Reload the checkpoint if you flip. In co-op, the player who stays behind while the other drives earns it even if the driver flips.

Complete The Maw on any difficulty.

Beat the 15:00 par time on The Maw.

Beat the 18,000 par score on The Maw.

Complete every CE level on Easy or higher. This comes with the Legendary sweep.

Complete every CE level on Normal or higher. This comes with the Legendary sweep.

Complete every CE level on Heroic or higher. This comes with the Legendary sweep.

Complete every CE level on Legendary, solo or co-op.

Beat par time on all ten CE levels. It unlocks after the tenth.

Beat par score on all ten CE levels. It unlocks after the tenth.

Activate all ten CE terminals. If one is missing, replay its mission in remastered mode and use the Save and Quit workaround if it will not activate.

Claim all 13 CE skulls in remastered mode.

Complete every CE level having seen it in both classic and remastered graphics. If you toggled during each mission, this unlocks after the tenth level. If not, replay any missing level, toggle once, and finish it.

Complete all CE Legendary missions in under three hours total. Your best Legendary time on each level counts, solo or co-op, and runs can be mixed. Check your times in the Career menu and replay the slowest missions. The per-level par times add up to 2:55, so par pace on Legendary leaves only about five minutes of buffer; beat par wherever you can. Use the Assault on the Control Room Banshee or corner-ride skip and the Keyes bump. This is one of the harder speedrun achievements in MCC; co-op makes it much easier.

Complete any Halo: CE playlist.

Complete three Halo: CE playlists. Vehicle Playground, Daring Escapes, and A New Threat are the quickest trio.

Complete the Halo: CE LASO Campaign playlist: all ten missions on Legendary with twelve forced skulls, including Iron and Grunt Funeral (Bandanna and Piñata are not included). Two-player co-op is supported and progress saves between sessions. With Iron in solo, a death restarts the whole mission; in co-op it reverts to the last checkpoint, which is why co-op is the standard approach. Solo players pause and Save and Quit before a death becomes certain to resume from the checkpoint. Halo Support advises skipping terminals during LASO because of the terminal bug. With Grunt Funeral and Boom active, beware lingering grenades; wait for them to go off before advancing.

Play a CTF custom game on Blood Gulch with four players. The original version required all four on one console; the current description dropped that wording, but split-screen players still count. Four controllers with guest profiles on one Xbox is the simplest option. The match only needs to be completed.

Complete a match on eight different classic CE multiplayer maps. Matchmade and custom games both count. Load a solo custom game with a low score limit on each map and end the game from the pause menu so the post-game carnage report shows. Quitting out does not count as completing a match.

Complete a match in four different CE game types. Use the same solo custom-game method, rotating game types.

Complete a level on Heroic or Legendary with only the Streaking skull active. Load The Heretic on Heroic, turn on Streaking and nothing else, and finish it.

Complete any campaign level on Normal or harder without dying. Your Heroic Heretic run for Starved For Shields unlocks this too if you do not die; otherwise The Heretic on Normal is the easiest choice.

Complete a level in co-op on Heroic or Legendary with the Masterblaster skull active. Masterblaster gives one player an overshield with melee only and the other no shields with infinite ammo, swapping after kills. Try The Heretic first with your co-op partner. It is not confirmed that The Heretic counts for this one; if it does not unlock, use a short real mission such as Cairo Station.

On Legendary, play The Armory and wait about 4:40 to 5:00 at the start until Johnson's line plays. The skull then appears on crates during the tram ride. It unlocks when you pick it up.

Terminal 1 is in Armory A-01, on the wall to the left of the Commons B-01 doors.

Find Marine Chips Dubbo on Cairo Station and fight beside him until his line plays. He also appears on Outskirts if you miss him here.

On Legendary, the skull is behind a displaced trash can on a high platform.

Complete Cairo Station on any difficulty.

This needs its own run. Play Cairo Station on Legendary with the Thunderstorm skull on and take no damage at all. When you reach the final bomb room, a PA message plays and the achievement unlocks. If you take damage, revert to the last checkpoint. If a checkpoint saves after you were damaged, restart the mission. The usual setup adds Envy (active camouflage) and Black Eye, and Scarab for more firepower; watch out for your own splash damage.

Beat the 15:00 par time on Cairo Station.

Beat the 14,000 par score on Cairo Station. This is one of the harder Halo 2 scores, so use Legendary with score skulls and avoid deaths.

This is the only Halo 2 skull that works on any difficulty. It is between buildings near a stash of grenades and a scoped weapon.

Terminal 2 is on the ground floor of the small beach building before the highway tunnels.

Stick a plasma grenade to one of the two Stealth Elites in Sniper Alley. They only appear on Heroic and Legendary, so this belongs on the Legendary run. Reload the checkpoint if you miss.

In a side room of Sniper Alley on Legendary. This skull only spawns in solo play, and its roughly one-in-seven spawn chance is rolled when the game loads Sniper Alley. Reach the checkpoint before Sniper Alley, then go to the skull room without triggering any further checkpoint. If the skull is not there, revert to that checkpoint to re-roll (or restart the mission). Elite waves follow the pickup, but you do not need to kill them.

Grab the energy sword stuck in the ground next to the word REX and a pool of blood (REX is spelled in rocks in classic graphics and in shotgun shells in remastered graphics). It works on any difficulty with no skulls, but the Easter egg does not appear in co-op and does not spawn on every load, for reasons nobody has documented. Do it solo on the same Easy run as Rooftop Runner, because the sword building sits on the rooftop path to Hotel Zanzibar, and keep it separate from your Legendary IWHBYD run, which fights through Sniper Alley at street level.

1. Leave the opening room with the crashed Pelican and crouch-jump onto the door frame, then up to the higher platform where the sky opens. Use a grenade jump if the crouch-jump will not reach; the Sputnik skull makes grenade jumps easier.
2. Cross the rooftops toward Hotel Zanzibar. If you fall early in this stretch, the crates let you climb back up.
3. Where the roofs run out, drop onto the highway, cross it, and climb back onto the buildings on the other side.
4. When two ramps appear, take the upward one. The downward ramp drops you off the roofs, and you will have to restart.
5. Find the building with two metal vents beside it and a large chunk missing from its roof. Drop through the hole into the top-floor room and pick up the sword. The achievement unlocks on pickup.

If the room is empty, the egg did not spawn on this load; restart the mission from mission select and try again. An Ultra Elite from the hotel area may come after you once you take the sword, so make sure the achievement has popped before you fight. A video of the jump sequence can help, but the landmarks above are enough. From the sword room you can continue across the rooftops to Hotel Zanzibar for the par time.

Complete Outskirts on any difficulty.

Beat the 15:00 par time on Outskirts. Jump across the rooftops from the start toward Hotel Zanzibar, grabbing the Rex Sword on the way.

Beat the 8,000 par score on Outskirts.

On Legendary, the skull is on top of the semicircular beam above the circular area.

Terminal 3 is in the Marine command post near the stairs.

On the street with three Wraiths, the Citizen Alert sign on the left before the pinned-down Marines flips between two versions. View both in remastered graphics.

Acquire the Scarab Gun, which sits on a traffic cone on the suspension bridges. With the Acrophobia skull on, fly straight to it. The Scarab skull does not count.

Shoot the soccer ball on Metropolis. Reach it with Acrophobia or a Banshee while you are getting Scarab Lord, or fire a hijacked Wraith at it.

Complete Metropolis on any difficulty.

Complete Metropolis on Heroic or Legendary without entering a vehicle. Do it on a separate Heroic run with Bandanna and the Scarab skull for extra firepower. Avoid turrets and passenger seats too, because it is not documented whether they count.

Beat the 15:00 par time on Metropolis.

Beat the 9,000 par score on Metropolis.

Kill seven enemies from behind in a row without being spotted. Any weapon works. The best spot is the group of sleeping Grunts in this mission: use active camo and work through them.

On Legendary, the skull is under the middle engine near dancing Grunts.

Terminal 4 is in the gas conveyor room, at the top of the far-right ramp.

Fly the Heretic Banshee. This happens naturally on The Arbiter (and again on The Oracle).

Complete The Arbiter on any difficulty.

Beat the 15:00 par time on The Arbiter.

Beat the 7,000 par score on The Arbiter.

In the four-pillar room, find the holo-drone floating in a vent before the Heretic Leader activates it. Break the glass and climb the platforms up to the vent and grenade-jump in, or fly up with Acrophobia.

On Legendary, the skull is in the third alcove, next to a dead Elite combat form.

Terminal 5 is in the large room after the lift, behind the far wall.

Complete The Oracle on any difficulty.

Beat the 25:00 par time on The Oracle.

Beat the 16,000 par score on The Oracle.

On Legendary, the skull is on a high wall between two invisible Elites.

Terminal 6 is to the left of the Prophet hologram display.

Collect the Master Chief toy in remastered graphics. Take a Ghost back toward the path with the Jackal snipers, boost up the cliff wall, and follow the lake ridge to a rocky peninsula.

Complete Delta Halo on Heroic or Legendary without entering a vehicle. Skip the delivered Scorpion. Pair it with the Commuter setup on a separate Heroic run with Bandanna and Scarab.

Complete Delta Halo on any difficulty.

Beat the 15:00 par time on Delta Halo. As the name suggests, leave the Scorpion behind.

Beat the 10,000 par score on Delta Halo.

On Legendary, the skull is on a rooftop balcony guarded by two cloaked Elites.

Terminal 7 is in the submerged sniper room, on the upper pillar behind the Regret hologram.

After the temple with the broken bridge, get into the hidden room. Either explosive-jump to the right-hand room with Sputnik on, or grenade-jump from the Hunter drop platform through a balcony window. Turn on your flashlight and zoom with a sniper rifle or beam rifle on the ceiling message in the left corner.

Collect the Prophet of Regret toy in remastered graphics by grenade-jumping across the collapsed bridge. Sputnik plus Bandanna makes the jump easy.

Complete Regret with the Prophet Birthday Party skull on, any difficulty. The easiest place is the Easy par-time run.

Complete Regret on any difficulty. Regret and Gravemind are widely considered the hardest Halo 2 Legendary missions.

Beat the 15:00 par time on Regret. This is one of the tightest Halo 2 pars.

Beat the 8,000 par score on Regret. Headshot every Jackal you can.

On Legendary, the skull is in the third alcove of the Flood area.

Collect the Arbiter toy in remastered graphics. It sits on a high conduit on the left side of the Grunt and Jackal room; use Sputnik for the jump.

Terminal 8 is in the final piston room, behind the right wall. This is the most-missed Halo 2 terminal, so look for it before the level ends.

Complete Sacred Icon on any difficulty.

Beat the 15:00 par time on Sacred Icon. Run through the level until the Sentinel Major.

Beat the 7,000 par score on Sacred Icon. The Sentinel generators keep producing enemies, which you can farm for points.

Terminal 9 is in the crashed Sentinel facility, on the lower level under the far platform.

After leaving the crashed Sentinel facility, an empty Scorpion sits off to the left. The earlier tanks are Flood-occupied. Drive it as the Arbiter to unlock this.

On Legendary, the skull is on a floating ledge on the cliff side.

Collect the Tartarus toy in remastered graphics. When you leave the gondola at the Library, it is on a high ledge to the right. Sputnik is required for the jump.

Complete Quarantine Zone on any difficulty.

Beat the 15:00 par time on Quarantine Zone.

Beat the 7,000 par score on Quarantine Zone. Sentinel generators again help with endless kills.

Load Gravemind on Legendary in classic graphics and watch the opening cutscene for the hidden developer. In remastered graphics a different character appears and the achievement does not unlock.

Terminal 10 is on the cliff top near the exit of the first Valley of Tears, behind the Jackal spawn.

On Legendary, the skull is on the wall above the gravity lift.

Collect the Cortana toy in remastered graphics at the end of the Valley of Tears A platform, near the Anger skull.

Kill a berserking Brute with a melee attack. Energy sword and Brute Shot melee both count. Gravemind has plenty of Brutes, and lower difficulties make this easier, so do it on the Easy par-time run if it did not happen on Legendary.

Complete Gravemind on any difficulty.

Beat the 20:00 par time on Gravemind.

Beat the 11,000 par score on Gravemind.

In the first room after the cavern, kill every Brute, then go to the corner with two dead Grunts and listen to the surviving Grunt.

On Legendary, the skull is in the rafters of the L-shaped hall. Grenade-jump up to it.

Collect the Librarian toy in remastered graphics in an alcove above the Jackal camp. Grenade-jump up the cliff.

Terminal 11 is in the area nicknamed Fight Club after the waterfall, in the second alcove before the stone bridge.

Complete Uprising on any difficulty.

Beat the par time on Uprising. One 2014 list gives 15:00, matching most Halo 2 levels, but that figure has a single source. Aim well under 15:00 and the achievement will tell you if you made it.

Beat the 9,000 par score on Uprising.

Collect the Rampant Cortana toy in remastered graphics. It is on top of the stone arch in the garden room and is the easiest toy in the game.

Terminal 12 is in the Sanctum of the Hierarchs.

On Legendary, ride the second big gravity lift and look up. Start holding the interact button before the skull reaches you, because it passes extremely fast.

Complete High Charity on any difficulty.

Beat the 15:00 par time on High Charity.

Beat the 9,000 par score on High Charity.

Terminal 13 is at the back of one of the jail cells where you free the Elite High Councilors and Hunters: the center-right cell on the upper level.

On Legendary, the skull is on top of the control room.

Collect the Didact toy in remastered graphics. Keep the Spectre from the start, drive into the water past the Scarab door, and climb the right-hand hills to the highest peak. Acrophobia also works.

Complete The Great Journey on any difficulty. Remember to turn the Scarab skull off for the Tartarus fight.

Beat the 15:00 par time on The Great Journey.

Beat the 8,000 par score on The Great Journey.

Complete every Halo 2 level on Easy or higher. This comes with the Legendary sweep.

Complete every Halo 2 level on Normal or higher. This comes with the Legendary sweep.

Complete every Halo 2 level on Heroic or higher. This comes with the Legendary sweep.

Complete every Halo 2 level on Legendary, solo or co-op. Having this achievement also makes you a valid target for other players' Legend Slayer in Halo 2: Anniversary multiplayer.

Beat par time on all 13 Halo 2 levels. It unlocks after the last one.

Beat par score on all 13 Halo 2 levels. It unlocks after the last one.

Activate all 13 Halo 2 terminals. The two prologue terminals do not appear to be needed.

Claim all 15 Halo 2 skulls. If one is missing, the usual culprit is IWHBYD on Outskirts.

Collect all eight hidden toys in remastered graphics.

Complete every Halo 2 level having seen it in both classic and remastered graphics. Replay any level you never toggled in and press the toggle once.

Complete all Halo 2 Legendary missions in under three hours total. Like the other speedrun achievements, this adds up your best Legendary time on each mission. Sources disagree on one point: Halopedia says solo or co-op times count, but the TrueAchievements solution and a Steam thread running from 2020 to 2025 say every Legendary mission must also be completed solo, and one co-op pair reported no unlock. Safest route: run the missions solo. Unlocks have also been reported as delayed, sometimes by hours, so check your total in the Career menu before redoing anything. The par times add up to about 3:30, more than the three-hour limit, so you need to beat par pace on Legendary. Regret and Gravemind are the hardest, and this is one of the rarest achievements in MCC.

Complete any Halo 2 playlist.

Complete three Halo 2 playlists. Boss Fights and Fan Favorites are the two shortest; add any third, or count LASO if you finish it first.

Complete the Halo 2 LASO Campaign playlist: every Halo 2 mission on Legendary with fourteen forced skulls (Envy is not included). It must be done through the playlist; turning on the skulls yourself does not count. Co-op is supported and progress saves between sessions. This is widely considered the hardest LASO playlist in MCC, so bring a reliable partner and use Save and Quit before a death would cost you progress.

On classic Ivory Tower, stand by the gate near the elevator and wait until the hidden music cue plays. The wait time is not documented, so be patient.

On classic Coagulation, look at the smiling face on one of the three rocks outside Red Base.

On classic Coagulation, find the "Not Sid" graffiti in the watery cave, on the upper level overlooking the pool.

On classic Beaver Creek, view the hidden message behind small rocks near the top of the map, above the sniper rifle spawn.

On classic Headlong, spot the hippo paintings on the walls of the central building under construction.

On classic Zanzibar, view one of the seasonal signs. These only appear on 1 January, 7 July, 31 October, and 25 December. Load a custom game on Zanzibar on one of those dates. Changing the console date while offline, viewing the sign, and reconnecting is commonly suggested, but it is not confirmed; playing on the real date is the safe method.

Complete a match on eight different classic Halo 2 maps. Custom games are confirmed to count for the matching Halo: CE and Halo 3 map-variety achievements and are expected to count here too: load each map, end the game from the pause menu, and repeat. If it has not unlocked after eight maps, finish the remaining maps in matchmaking.

Complete a match in four different game types on classic Halo 2 maps, using the same method.

Die from something the game cannot attribute to anyone, so the kill feed says you were killed by the Guardians. Halopedia's examples include being hit by the train on the classic Halo 2 map Terminal, Brute landmines on Halo 3's Sandtrap, and lingering in the timed kill zone of the Forward Unto Dawn wreckage on Halo 4's Dawn. While you are loading classic Halo 2 maps, start a solo custom game on Terminal and stand on the tracks until the train hits you. If that does not unlock it, use the Dawn kill zone during your Halo 4 runs.

Stand at Blue base facing the middle of the map. The can sits on a rock in a crack in the canyon wall to your left, faintly visible through a sniper scope. Shoot it from Blue base; if the angle is awkward, move closer to the cliff.

The can is on a ledge behind the central hanging ice. On a fresh map load, stand near the gravity lift and scope toward the cracks behind the central icicle. Shoot the can directly without disturbing the ice or picking up power-ups first; one player reported three failed unlocks after moving the ice and a successful one after an undisturbed shot. Only shoot the icicle down if it blocks your view. If the achievement does not unlock, restart the game and try a clean shot. Do this before your Cold as Ice session with a partner.

On the top level of the yellow/gold side of the map, a tree root grows down into the back-right corner as seen from the middle. The can is in a crack in the wall just behind the root, among rocks and leaves. Walk up and shoot or melee it; no sniper is needed.

By the sniper tower, climb the crates next to the big rock and stand on the blue container, facing the tower's support. The can is on the small platform beneath the tower. Shoot it, ideally with the Sniper Rifle.

On the bottom floor of the power station (the large base), scaffolding covered with a blue tarp has two crates on top. The can sits between the crates. Jump up and shoot or melee it.

The can is out of bounds, on top of a crumbling temple in the background behind and to the left of Red base as seen from the middle of the map. From the Eastern Rise area facing the base, look at the temple's two pointed tops; the can is on the right-hand top. Shoot it with the Sniper Rifle at 10x zoom, because it cannot be reached on foot.

Destroy the cans on the six original Anniversary maps: Bloodline, Lockdown, Warlord, Zenith, Stonetown, and Shrine. It unlocks after the sixth can. Remnant is not required.

Destroy the BLAST can on Remnant. It is in the sea near the Albatross dropship: stand behind the stone arch and look down at two rocks sticking out of the water. The can is between them, next to the smaller rock, just under the surface. Aim down into the water and shoot it. One player comment calls the Remnant can bugged without details; if it does not unlock, reload the map and try again.

Complete a game on each of the six original Anniversary maps. Do it while hunting the cans: after destroying each can, end the game from the pause menu.

Win 10 matches on Bloodline. A 2020 to 2022 guide reports that loading a solo custom game on Bloodline and ending it immediately counts as a win. This was not re-confirmed for 2025 or 2026, so check the progress after one or two games. If solo wins stop counting, play Bloodline custom games against your second player and win them.

Survive 30 seconds as the Juggernaut. Start a solo custom Juggernaut game and wait.

Control three territories at the same time for 30 seconds. Set up a solo custom Territories game with three territories, capture all three, and hold them.

In Assault, pick up the bomb from its spawn, plant it, and score without dying or dropping it. A solo custom Assault game works.

On Warlord, collect five active camouflage power-ups in a single game. Start a long solo custom Slayer game on Warlord, wait at the center camo spawn, and grab each one as it respawns.

On Shrine in CTF, trigger the enemy base waterfall and grab the enemy flag before the waterfall stops. A solo custom CTF game on Shrine works.

Kill an opponent by detonating a Fusion Coil. Have your partner stand next to a coil on a map such as Lockdown or Stonetown and shoot it.

On Lockdown, kill an opponent with the hanging ice. Have your partner stand under an icicle and shoot it down. Each map load has three icicles.

Kill an enemy who is zoomed in, using a Sniper Rifle or Beam Rifle. Have your partner zoom in with a sniper while you shoot them.

Get a kill with the Gungoose while it is airborne. On Bloodline, launch the Gungoose off a ramp or man cannon and hit your partner in the air.

Get 25 kills with the Gungoose. This is cumulative across games. Keep farming your partner on Bloodline after Top Gungoose.

Get 30 kills with the Hornet. This is cumulative. Farm your partner on Bloodline.

Kill 15 opponents who are airborne after launching from a man cannon. This is cumulative. On Bloodline, your partner launches from a man cannon again and again while you shoot them mid-air.

In one match, steal five occupied vehicles from opponents. Your partner drives a Gungoose or Ghost on Bloodline and you hijack them five times.

Destroy a piloted Banshee or Hornet in flight with the Rocket Launcher. Your partner flies a Hornet on Bloodline while you rocket it.

Get 25 melee kills. This is cumulative. Melee your partner repeatedly in any custom game.

In King of the Hill, kill five opponents while you stand inside the hill your team controls. Set up custom King of the Hill and have your partner walk toward the hill repeatedly while you defend from inside it.

Earn at least 10 different medals in one game. Older wording specified a non-team game, so play free-for-all to be safe. Mix kill types against your partner (headshot, melee, assassination, grenade, splatter, double kill if you have two targets) or let it come naturally in matchmaking.

Kill an opponent who has the Legendary Anniversary achievement. A guest profile will not have it, so either kill a friend who has completed Halo 2 on Legendary in a custom game, or let it happen naturally in Anniversary matchmaking.

In one Ricochet match, pass the ball once, score once, and kill at least one enemy. You need a teammate to pass to and an enemy to kill, so three players. On Xbox, three-player split-screen or a mix of local and online friends works.

Earn two or more Double Kill medals in one Anniversary game. You need at least two opponents for a double kill. It also tends to happen naturally in matchmaking.

Stop another player's killing spree in Halo 2 Classic or Anniversary matchmaking. This comes naturally.

Kill five people with melee from behind in Anniversary matchmaking. This is cumulative across matches.

Kill an opponent who has Ninja Redux in Anniversary matchmaking. Many players have it, so it comes naturally.

Win 10 Anniversary matchmaking games with Elite selected as your species in customization. Set Elite in your Halo 2 Anniversary multiplayer customization before you queue. Halopedia says custom games once counted, but the current description specifies matchmaking, so plan on matchmaking.

Finish as the top player on the winning team in a matchmade game. Objective modes or a 2v2 with a strong partner make this easier.

On Zenith, personally activate the center energy shield three times in one matchmade game. Hold interact at the control panels each time it becomes available. Getting Zenith in matchmaking is the bottleneck.

Earn 100 Splatter medals in Anniversary matchmaking. This is cumulative and needs vehicle maps such as Bloodline or Zenith to come up. It is one of the rarest achievements in MCC. Track it across your whole matchmaking phase and join community boosting events when they run.

Earn 100 Environmentalist medals in Anniversary matchmaking: kills with Lockdown's falling ice or exploding Fusion Coils. As of 2024 and 2025, the best-known method is queuing 1v1 when Lockdown comes up, where around 15 environmental kills per match are possible, ideally with a boosting partner searching at the same time.

Find the first clue in Mombasa Streets. It unlocks during the story and leads into Tayari Plaza.

Find the second clue. This leads into Uplift Reserve.

Find the third clue. This leads into Kizingo Boulevard.

Find the fourth clue. This leads into ONI Alpha Site.

Find the fifth clue. This leads into NMPD HQ.

Find the sixth clue. This leads into Kikowani Station.

Once VISR database access opens, find the Web-O's cereal box in the first building: on the floor to the right of the courtyard door, in front of a couch. Center your view on it.

Kill five sleeping Grunts in Mombasa Streets. The area around Rally Point 5 has a group. Quietly melee or headshot them before they wake.

Kill 10 Engineers. Mombasa Streets at night has the most Engineers. A charged plasma pistol shot drops them quickly. Kill every Engineer you see during your hub runs.

Kill 25 Engineers. Keep going in the hub; the audio-log sitting later gives you plenty more chances. Halopedia also says Halo: Reach Engineer kills count, but no other source confirms it, so plan to finish here.

At the start, melee the first Marine on the head to knock his helmet off. The achievement unlocks when it comes off.

Earn a Triple Kill medal with the pistol. The Grunts up the ramp at the start are the best targets, especially on Easy.

Kill four enemies with a single plasma or frag grenade. Throw it into a group of Grunts as a dropship unloads them.

Finish Tayari Plaza with at least one Marine still alive. On Easy, rush ahead and keep the fighting away from the Marines. In co-op, one player can stay back while the other heads for the exit.

Complete Tayari Plaza on any difficulty.

Beat the 3:00 par time on Tayari Plaza. Play on Easy and sprint through.

Beat the 8,000 par score on Tayari Plaza with scoring on.

Finish any level solo on Legendary with no shots fired and no grenades thrown. This is the strictest condition in the stack.

Complete any level without activating VISR mode.

Complete any level without using Covenant weapons.

Complete any level on Heroic or Legendary without dying.

Complete any level on Heroic or Legendary without using a health pack.

Complete Uplift Reserve on any difficulty.

Beat the 4:00 par time on Uplift Reserve. If your restriction run comes in under four minutes, this unlocks at the same time. Otherwise do it on Easy.

Beat the 14,000 par score on Uplift Reserve with scoring on.

Pilot a Banshee on Kizingo Boulevard. Hijack or find one and get in.

Complete Kizingo Boulevard on any difficulty.

Beat the 9:00 par time on Kizingo Boulevard. A vehicle shortens the run.

Beat the 18,000 par score on Kizingo Boulevard with scoring on.

Destroy seven Wraiths on ONI Alpha Site. Exactly seven appear across the level, four at the bridge and three in the inner courtyard, so you need every one in a single run. Save Spartan Laser ammo for the courtyard and use the Gauss cannons at the entrance. Restart the mission if you miss one.

Destroy a Wraith with your bare hands: board it and melee or plant a grenade until it blows. ONI Alpha Site has plenty of Wraiths.

Kill three jetpack Brutes with a shotgun. They appear in the outdoor fight after the elevator.

Complete ONI Alpha Site on any difficulty.
