54 achievements in this guide

Before You Start

Gears of War: E-Day has 54 achievements worth 1,000 Gamerscore on the shared Xbox Series X and S and Windows list. All of them are in the base game. There are no DLC or title-update achievements yet. Earning all 54 also awards Xbox's Mythic Achievement, which is not one of the 54 and is worth 0 Gamerscore. The Steam version still lists a 55th, 0G "earn everything" achievement. It was removed from Xbox on 1 October 2026 and does not apply here.

The completion has two halves. The campaign half is one Insane clear plus 100% War Journal completion, one full co-op clear, and a handful of combat tricks. The multiplayer half is a long online grind: five full passes of Player Level 100, all four Horde Siege classes at max level, 50,000 Horde Siege kills, 25,000 Versus kills, and some Allfather-difficulty Horde.

Playthrough Plan

Run 1: solo campaign on Insane, with full cleanup. This run covers Remember Kalona, Today We Are Canceling the Apocalypse, every story achievement, and as much of the 100% War Journal work as you can manage: collectibles, Hard Cases, Secondary Objectives and Supply Cache stations, plus the Quartermaster item pickups. Insane is selectable from the start.
Run 2: full campaign in co-op, any difficulty. This covers You're My Brother. You can play it on Casual with a partner. It also gives you a second pass for anything you missed.
Chapter select lets you replay any chapter to mop up collectibles. The 100% part of For Whom the Bell Tolls counts on any difficulty, so cleanup can be done on Casual.
Horde Siege and Versus are separate from the campaign. Start them early and play them alongside the campaign. Every kill, revive, mission and level counts toward cumulative achievements from your first match.

Why solo for Run 1: as of October 2026, War Journal counters can get stuck one short (see Status below). Reports come from solo and co-op play alike, so going solo is no guarantee. It does keep the run simple, and every item is recorded on your own profile.

If you would rather do a 100% run on Normal before attempting Insane, that works. It just adds a third campaign run.

Difficulty Settings

The campaign difficulties are Casual, Normal, Hardcore and Insane. The difficulty menu lets you customize individual settings. If you customize, the game treats your overall difficulty as the lowest setting you picked. For the Insane run, leave every setting at Insane.

The War Journal appears to record difficulty per act, so lowering it even briefly may cost you the Insane credit for that act. Required for safety: keep the whole Insane campaign on Insane, in one save, from start to finish. Finish each chapter rather than quitting partway, since quitting mid-act can leave the War Journal out of step. Check the War Journal's difficulty record at the end of each act.

In co-op, each player chooses their own difficulty.

Online, Co-Op and Server Requirements

The campaign plays offline. Co-op supports up to 4 players online, or 2-player split-screen on console.
Horde Siege and Versus require an online connection and an Xbox online multiplayer subscription or Game Pass.
Horde Siege has no private lobbies at launch. Empty squad slots are filled with AI bots.
Versus has a Player vs Bots playlist. Ranked opens on 13 October 2026.

Missables and Points of No Return

Nothing in the campaign is permanently missable, because chapter select can replay any chapter. Inside a chapter, though, several Secondary Objectives, Hard Cases and collectibles are only available during certain story windows. Leaving the window means replaying the whole chapter. The route below warns you before each of these:

Act 2 Chapter 2, Hold the Line: the biggest open district in the game, in three parts. Leaving Part 1 (Octus Way Station) is treated as one-way. Entering the Octus Tribunal Muster Point, the courthouse after you link up with Charlie Squad, is one-way. Everything in Parts 1 and 2 must be done before it.
Act 2 Chapter 5, Overrun: the final hangar room ends the act.
Act 4 Chapter 2, Technical Difficulties: a set of COG tags at the first train stop must be grabbed before the train leaves.
Several other collectibles and Hard Cases sit just before one-way doors, boss arenas or train rides. Each chapter below flags them under Timing.

Hard Cases behave differently from collectibles on replay. Your War Journal Hard Case count for each act carries over, and cases you find on a chapter-select replay are reported to add to that count. But the chapter you reload is reset: cases you already opened respawn and are no longer marked, and your loadout temporarily loses the mods that chapter's cases gave you. Loading a late chapter gives you back every mod you have earned. Recommended (for efficiency, not a requirement): sweep every Hard Case during the Insane run, so cleanup stays small. Do any gap-filling after the Insane finale, or in a separate save slot (the game has five), so the Insane run itself never reloads earlier chapters.

Status as of October 2026

War Journal counters stuck one short: CURRENTLY COMMUNITY-FLAGGED / BUGGY (October 2026). An act counter can show one item missing (for example 40/41 collectibles in Act 4) while the expanded list shows everything found. It has been reported for collectibles, Secondary Objectives and Hard Cases, after solo runs as well as co-op and join-in-progress sessions. The cause is not known. The 5 October 2026 patch changed how join-in-progress players receive War Journal progress but did not fix this counter. Protect yourself by checking the War Journal at the end of every act: each act's collectible, Hard Case, Secondary Objective and Supply Cache counts, plus the difficulty recorded. If an act total is one short while its expanded list is complete, try the community-reported workaround: join another player's campaign as a guest, with that player hosting and not yet having collected the items, and replay the affected act until your count updates. It has worked for some players but not all, so it is not a guaranteed fix. Reinstalling, reloading checkpoints and re-collecting are reported not to help.
Long campaign sessions: HISTORICALLY REPORTED BUG (launch known issue). The launch notes warned of memory problems when playing very long stretches without reloading. Restart the game between acts.
No achievement is currently confirmed unobtainable.

Boot Camp and First Steps

Boot Camp

The game offers Boot Camp on first launch. If you skipped it, go to Practice on the main menu and pick Boot Camp. It takes under five minutes.

FNG

FNG15G

Unlocks when you finish Boot Camp. Do it before the campaign so the controls are fresh for Insane.

Cumulative Achievements to Start Now

These progress anywhere and are worth knowing from minute one.

Just Let Me Get One More…

Just Let Me Get One More…15G

100 revives in total. It counts revives of downed (DBNO) players: AI teammates in the campaign, plus revives in Horde Siege and Versus. Bringing back dead Horde Siege players by delivering their COG tags to a Supply Cache does not count. On Insane your AI squad goes down often, so always pick them up. Between the campaign and Horde Siege's Medic work, this will finish on its own.

Brotector

Brotector15G

Free another player who has been grabbed by a Locust and is struggling. Primary method: during the co-op run, or in Horde Siege, watch for a human teammate locked in a struggle and break it immediately. Whether rescuing an AI teammate in the solo campaign counts is not verified, though it costs nothing to try, so free any AI squadmate you see grabbed as well.

Act 1

Act 1 has 13 collectibles and no Hard Cases or Secondary Objectives. Collectibles give no on-screen pop-up. Listen for the short musical sting and use Tac-Com (LB) to highlight anything nearby. Each chapter below lists its collectibles in route order; the exact location of every one is in the Collectibles tracker at the end of this guide.

Prologue and Chapter 1: Emergence

Collectibles

Monster Jaw — Act 1, Emergence. On the ground beside the first E-hole near the newsstand kiosk. It only appears once you regain control after the first Wretch fight and cutscene, so look around before moving on.
Bloody Transit Worker's Helmet — Act 1, Emergence. In the maintenance tunnels, in an optional side room off the left of the deeper corridor, next to a corpse lit by a flashlight.
Front Page of the Kalona Times — Act 1, Emergence. In the kitchen at the back of the Cafe and Bakery across the street. Free the pinned civilian and clear the street first, then go through the optional building.

Chapter 1 has 3 collectibles. Search every side room before moving on.

Collectibles here, in route order: Monster Jaw, Bloody Transit Worker's Helmet, Front Page of the Kalona Times.

Chapter 2: Survival of the Fittest

Collectibles

KPD Police Bulletin — Act 1, Survival of the Fittest. On a desk near the back left wall of the first big station office, right in front of a corkboard. It is early in the chapter, so grab it before moving deeper.

Try On Pilot Helmet — Act 1, Survival of the Fittest. In the same Recruiting Center, the third helmet from the left in the display row beside the pamphlet. One guide reverses left and right, but it is the same display. Also listed as Try on Pilot Helmet.

4 collectibles.

Chapter 3: A Gear in Need

Collectibles

Tomatoes, Canned — Act 1, A Gear in Need. In the Pay-N-Save stock area: second storage room, leftmost floor row, near a corpse. It is early in the chapter, so check the storerooms first.
Broken Lancer Bayonet — Act 1, A Gear in Need. After the supermarket defense cutscene, on or under the Locust that attacked Marcus, right at your feet. It only exists after the cutscene and is easy to miss.

2 collectibles.

Collectibles here, in route order: Tomatoes, Canned, Broken Lancer Bayonet.

Collectibles here, in route order: Front Page of the Tyran Chronicle, Anti-UIR Propaganda Poster, Landa Memorial Medical Supplies Memo, COG Tags of Private Brick Rosso.

Act 1 Wrap-Up

Check the War Journal shows Insane recorded for Act 1. These three unlock during Act 1 as you progress the story. Their descriptions only say "Unlock during Act 1," and no extra action is known to be required. Before you start Act 2, check that all three have unlocked and that the War Journal shows 13/13 collectibles for Act 1.

Emergence Begins

Emergence Begins15G

Unlocks during Act 1 through story progress.

We Must Improvise

We Must Improvise15G

Unlocks during Act 1 through story progress.

The Bigger They Are…

The Bigger They Are…15G

Unlocks during Act 1 through story progress. If any of the three is still locked after Act 1, replay the act from chapter select before going further.

Act 2

Act 2 opens Kalona up. It has 38 collectibles, 36 Hard Cases, 11 Supply Caches and all 7 of its Secondary Objectives in one district. It is also where you first meet Supply Caches.

Hard Cases, Supply Caches and Quartermaster

Hard Cases are yellow briefcases. Each one unlocks a weapon mod, mod slot, gear mod or perk, which you equip at campaign Supply Caches. Hard Cases are much easier to spot than collectibles: a pop-up appears in the top-left when one is close, and Tac-Com and the map show it. The War Journal shows a Hard Case count for each act, but not per chapter, and it does not show which case is missing. To find gaps, compare the act count, then open a Supply Cache and look for mods that are still locked. Where a locked mod doesn't point to one case, work through that act's location list in the Collectibles tracker instead.

Campaign Supply Caches are free loadout lockers. They cost nothing and you cannot run out. They also count toward 100%: the War Journal has a Supply Caches Found counter for each act, 36 in total (none in Act 1, 11 in Act 2, 8 in Act 3, 13 in Act 4 and 4 in Act 5). A pop-up appears when one is near, the map then shows it, and it gets a checkmark once found. Walk up to every cache and open it to be safe, since it isn't confirmed whether just getting close counts. Each chapter below lists its caches. Most sit on the main path.

Quartermaster

Quartermaster15G

Unlocks when every weapon, tactical gear item and piece of equipment the campaign offers has been picked up and unlocked at Supply Caches. Finding cache stations is a separate 100% requirement (see above) and does not count toward Quartermaster, which comes from picking items up. If the achievement's progress stalls short with every item seemingly collected, a community-reported fix is to replay the chapter where the missing item first appears and pick it up again. It is not guaranteed.

The achievement's own wording only says "all Supply Cache items." The 27-item checklist below comes from guide research, not from the achievement text, so treat the Supply Cache menu as the authority. Items by the chapter where each first appears:

Act 1 Chapter 1: Snub, Gnasher
Act 1 Chapter 2: Lancer Mk1, Hammerburst
Act 1 Chapter 4: Gut-Puncher, Frag Grenade
Act 2 Chapter 1: Breechshot
Act 2 Chapter 2: Prototype Lancer, Longshot, the four signature weapons (Fenix's Proto Lancer, Carter's Gut-Puncher, Reyes' Longshot, Santiago's Gnasher), Sonic Disruptor, Adrenaline Injector, Concussion Grenade, Machine Gun Sentry
Act 3 Chapter 1: Incinerator
Act 3 Chapter 2: Striga, Razor Mine
Act 3 Chapter 3: Ripper, Pulse Drone, Stim Vaporizer, Smoke Grenade, Incendiary Grenade, Stim Grenade
Act 3 Chapter 5: Torque Bow

Required: pick up one of each yourself. In co-op, a host's pickup may not count for a guest. The easiest way to confirm is the Supply Cache screen itself. If anything is still locked after Act 3, it tells you exactly what to go back for. Treat the Supply Cache screen as the final word. The unusual weapons, such as the Torque Bow, Incinerator, Striga and Ripper, are the ones most likely to be left on the floor. Swap to every new weapon you see, even if only for a moment. Reminders appear in the chapters below.

Chapter 1: Bravo Squad

Collectibles

This is the most important chapter in the campaign. It has 27 collectibles, 27 Hard Cases and all 7 Act 2 Secondary Objectives, spread across three parts. Part 1 is North Kalona, around Octus Way Station: 3 collectibles and 1 Hard Case. Part 2 is East Kalona: 18 collectibles and 18 Hard Cases.

Quartermaster: this chapter is where most items first appear. Pick up the Prototype Lancer, Longshot, all four signature weapons, the Sonic Disruptor, Adrenaline Injector, Concussion Grenade and Machine Gun Sentry when you find them.

Side Piece

Side Piece15G

Unlocks when all 17 campaign Secondary Objectives are complete, on any difficulty: 7 in Act 2, 3 in Act 3 and 7 in Act 4. The War Journal counts them per act. Act 1 and Act 5 have none.

In this window, do these in order as they appear:

The Vanguard: at the Iron Coast Motors car dealership east of Oria Stadium. It opens once you have finished the map and orders steps and the game lets you into the open district. Inside the dealership, talk to the COG soldier by the far entrance and accept the prompt to start the defense.

Part 2 runs until you enter the Octus Tribunal Muster Point, the courthouse where you meet the Gear at the far end after linking up with Charlie Squad. That entry is one-way.

Collectibles here, in route order: Kalona Postcard, Vandalized Salvaging Poster, COG Tags of Private Liz Waxman, Emgazi Blitz Display Case, Birthday Card With Toy Lancer, COG Tags of Master Sergeant Mark Avamor, Major Burger Box, COG Tags of Specialist Brendan O'Connell, COG Tags of Specialist Arnold Imhatip, Caricature of Colonel Elias Trench, Re: Vibration Complaints, Timgad Refinery Recruitment Poster, Photograph and Harmonica From Mags' Apartment (automatic), COG Tags of Specialist Jada Clemmons, War Savings Bond, Kalona Metro Fare Notice, Tales From the Tyran Night Story Book, Foreman's Datapad.

Hard Cases here: 18. Each one is listed with its location and reward in the Collectibles tracker at the end of this guide.

One inside the southernmost Major Burger. One inside the Kalona Police Department on the west side of the Warehouse District.

Timing:

Foreman's Datapad: Take when the construction site objective sends you there, before Link up with Charlie Squad.
Bank of Tyrus vault: Take it as soon as the vault opens, before the Muster Point.
Charlie Squad camp tent: Last case before the point of no return; take it before speaking to the Gear at the camp end.
Warehouse District entrance wall: Take it before the Imulsion container detonates, and before the Muster Point.
Warehouse District dead-end alley: Take it before the Imulsion container detonates, and before the Muster Point.

Apartment SOS: in the apartments east of Octus Tribunal. You get in through a window.
Lost in Translation: an escort around Major Burger. It becomes available after the Amberstone section, while your objective is "Get Mags' meds."
Family Reunion: at Shelter 13 in Victory Plaza, defending the shelter and the civilians inside. It only appears after "Get Mags' meds." Finish it before you link up with Charlie Squad. The game locks it behind the courthouse gate.

Many guides list only six Act 2 objectives because they miss the shelter defense. Check the War Journal for 7.

Some items in this chapter are awarded through story or objective steps:

The Photograph and Harmonica collectible comes from Mags' apartment during "Get Mags' meds."
The War Savings Bond collectible and a Hard Case come from the Dr. Fabbri vault objective.
One Hard Case is behind the "Secure the Imulsion stockpile" objective.

Right in the Ticker

Right in the Ticker15G

Unlocks when you kick a Ticker so it flies back and blows up among the enemies. The best spot is the bank defense in this chapter. When an E-Hole opens, Tickers pour out. Kick one straight back toward the hole and the enemies around it. If it does not unlock, keep kicking Tickers back into groups of enemies. Tickers come up in most fights from here on.

Okay, Boomer.

Okay, Boomer.15G

Unlocks when you chainsaw a Boomer. You cannot chainsaw a Boomer at full health. Damage it first, with a couple of headshots or grenades and Gut-Puncher rounds, then rev the chainsaw and close in. Boomers appear in this chapter, and there is a chaingun Boomer at the church in Act 4 Chapter 1 as a backup. Coming from behind may help. Try it on the first Boomer you see here. On Insane, use cover and make sure the Boomer is badly hurt before you commit.

Chainsaw Go Brrrrrrrrr

Chainsaw Go Brrrrrrrrr15G

Unlocks when you kill a Locust with a Lancer chainsaw, in the campaign or in Horde Siege. There are no chainsaw duels in this game, so a normal chainsaw kill is the target. It may not trigger with Marcus's signature Proto Lancer. Safest route: Use the standard Prototype Lancer as soon as you have one (it first appears in this chapter), and chainsaw a weakened Drone or Wretch. Any Lancer chainsaw kill along the way may also work.

Payback's A Pitch15G

Unlocks when you kill an Armored Wretch while you are still stunned by its scream. Armored Wretches have metal gauntlets and knee pads. The stun shakes the screen and drains the color. Kill that Wretch before the screen returns to normal. A chainsaw or quick melee hits work, and other methods probably do too. On solo, your AI squad often kills the Wretch first, so stay close to it and act immediately. If it does not happen here, the Corpser fight in Chapter 2 sends Wretches at you about halfway through. Later acts have plenty more.

I Am Heavy Weapons Guy

I Am Heavy Weapons Guy15G

Unlocks when you kill 10 enemies in a row with one detached turret. Before starting any objective, go to Landa Memorial Hospital. A mounted turret sits on the roof above the entrance. Detach it and keep holding it. Carry it to the underground parking lot, where there is also a Hard Case. E-Holes open there and pour out enemies, mostly Tickers, and they all count. Fire in short bursts, and do not put the turret down or swap weapons until it unlocks.

Secondary Objectives in this chapter:

Weak Signal: in the building south of Landa Memorial Hospital. It starts near the police department.
Lost in the Park: it only appears after the Kalona Hotel story beat, where you help load the convoy and fight off the Spore Matrons. Start it at the glowing prompt on the right side of the hotel as you face it. If the prompt isn't there, finish the hotel beat first. Go through the doors on the right into the park, clear the Locust, and find the civilian under the steps. Completing it also awards the Damaged Heavy Locust Helmet collectible.
Rooftop Mayday: follow the flare north of Monroe Library. It also awards the Blade-Like Projectiles collectible.

Explosive Indigestion

The best spot reported is the start of the convoy defense in this chapter, at the top of the steps, where two Bilefrogs come at you. Hide behind the wall, let one get close, and fire into its mouth. Bilefrogs keep appearing later, so there are more chances.

Two Grubs, One Gut-Punch

Two Grubs, One Gut-Punch15G

Unlocks when one Gut-Puncher round hits two Locust. Hold RT to control where the round bursts. The orange grid shows the blast area. Release it in the middle of a tight group. Any heavy swarm works, and this chapter's E-Hole fights are ideal. Pick up a Gut-Puncher here and keep it in your loadout until this unlocks.

5 collectibles. Before the finale, check the War Journal's Act 5 counts, including Supply Caches. Then open a Supply Cache here and go through every weapon and gear mod. Any locked mod means a missed Hard Case somewhere. Match it against the Hard Case rewards listed in the Collectibles tracker. This check only narrows things down: mod slots are counted rather than listed individually, and a few cases share the same reward. The War Journal's per-act Hard Case total is the final word. Note what is missing, but finish the campaign before reloading earlier chapters. Reloads respawn that chapter's Hard Cases and temporarily strip its mods from your loadout, and keeping the Insane run straight through avoids any risk to its difficulty record. Gap-filling afterward still counts. Confirm Quartermaster has unlocked too.

The War Journal counts them per act, and that count is reported to carry across chapter-select replays, so a case you pick up during cleanup still adds to your total. Sweeping them all during the Insane run is simply the efficient way to do it. If the achievement has not unlocked by the end of the campaign, compare each act's War Journal count with the totals above, then use the gaps you noted at the Act 5 Chapter 4 cache. After the finale, or from a separate save slot, load each chapter that holds a missing case with chapter select. Grab the case, then quit. You don't need to finish the chapter. Where a locked mod doesn't narrow things to one case, check every case on that chapter's list in the Collectibles tracker.

Chapter 5: The Fall of Kalona and Epilogue

Collectibles

COG Tags of Sergeant Alton Hau — Act 5, The Fall of Kalona and Epilogue. On the opening bridge, left of the first checkpoint, by a burning car.
COG Tags of Sergeant Bryce Valen — Act 5, The Fall of Kalona and Epilogue. Awarded automatically after the second Impaler is defeated at the end of the final boss. Nothing to find.
Carlos Santiago's COG Tags and Photo — Act 5, The Fall of Kalona and Epilogue. Awarded automatically during the credits or ending. Nothing to find.

3 collectibles. Two of them are awarded by the final boss fight against Vraahk and by finishing the campaign, so you get them automatically.

Collectibles here, in route order: COG Tags of Sergeant Alton Hau, COG Tags of Sergeant Bryce Valen (automatic), Carlos Santiago's COG Tags and Photo (automatic).

Supply Caches here: 2 cabinets. One is in the bridge colonnade near the kiosk where Alton Hau's tags are, and a second comes later in the chapter. Open both. Between Resolute and this chapter, the War Journal should reach 4/4.

Timing:

COG Tags of Sergeant Alton Hau: Grab at the opening checkpoint.

Remember Kalona

Remember Kalona25G

Unlocks when you finish the final act, on any difficulty.

Today We Are Canceling the Apocalypse

Today We Are Canceling the Apocalypse25G

Unlocks when every act has been completed on Insane. An Insane clear should also satisfy Remember Kalona, since that one accepts any difficulty.

Nothing Left but the Fight

Nothing Left but the Fight15G

Unlocks during Act 5 through story progress.

For My Boys

For My Boys15G

Unlocks during Act 5 through story progress.

Campaign Cleanup and Co-Op Run

100% Cleanup With Chapter Select

Open the War Journal and check each act. Collectible progress carries across difficulties and runs, so replay any chapter with gaps on Casual from chapter select. Collected items stay marked on the map from earlier runs. Hard Cases behave differently: they are not marked from earlier runs, and reloading a chapter respawns them, but new finds on a replay are reported to still count. Use each act's War Journal count and the gaps you noted at the Act 5 Chapter 4 Supply Cache to decide which chapters to reload. Grab each missing case and quit.

Memories From E-Day

Memories From E-Day15G

Unlocks when all campaign collectibles are found, on any difficulty. There are 140: 13, 38, 36, 41 and 12 across the five acts. The War Journal lists every collectible by name, so a missing name tells you exactly which entry in the Collectibles tracker to look up. If an act shows one short while its expanded list is complete, you have hit the counter bug. The community-reported workaround is joining a friend's game as a guest, with the friend hosting and not yet having collected the items, and replaying that act until your count updates. It has worked for some players but not all.

For Whom the Bell Tolls

For Whom the Bell Tolls75G

Unlocks when the campaign has been beaten on Insane and the War Journal shows 100% completion. The 100% part counts on any difficulty. 100% means every collectible (140), every Hard Case (125), every Secondary Objective (17) and every Supply Cache station (36), each tracked per act in the War Journal. With the Insane run done and the cleanup above finished, this should unlock when the final item registers.

Co-Op Campaign

You're My Brother

You're My Brother15G

Unlocks when every act of the campaign has been completed in co-op, on any difficulty. Online co-op supports up to 4 players, and console split-screen supports 2. Each player picks their own difficulty, so Casual is fine.

Nobody has confirmed whether a chapter-select co-op run counts, or whether guests get credit as well as the host. The 5 October 2026 patch changed what players joining a campaign in progress receive: they no longer get War Journal progress the host earned before they joined. An online guest has also been reported ending up with no progress in their own save. Safest route: start a fresh campaign in co-op and play it straight through from Act 1 to the Epilogue in one save. Every player who needs the achievement should be in from the first chapter and stay until the end without dropping out. If two players both need it and the guest's credit is in doubt, run it again with host and guest swapped. The run also gives you another chance at Brotector, any missed Quartermaster pickups, and Payback's A Pitch.

Horde Siege

Horde Siege is 12-player PvE: three squads of four share a district of Kalona, each with its own mission. You complete objectives, mostly guarding or repairing R.I.G.s, then survive at the landing zone until a Raven extracts you. Empty squad slots are filled with bots, and there are no private lobbies. Playlists run from short Blitz missions to long 10-wave Horde missions.

Difficulties, in order, are Rookie, Infantry, Commander and Allfather. Allfather is meant for max-level classes. Class XP comes from completed missions and is separate from your Player Level.

Start here early and mix it in with the campaign. Many achievements below are cumulative and fill in during normal play.

First Mission and Onboarding

Crepe du Raven

Crepe du Raven15G

Unlocks when you get crushed by a landing Raven. When the extraction Raven comes in, stand directly under it as it touches down. Any Horde Siege mission works, including Onboarding. This kills you, so do it on an easy mission where your squad can still extract.

The Four Classes

Each class carries one piece of Tactical Gear tied to an achievement. Each class levels to 30.

Assault: Sonic Disruptor (stuns enemies in a forward cone)
Breacher: Adrenaline Injector
Marksman: Pulse Drone (reveals enemies)
Medic: Stim Vaporizer (heals and revives downed players in range, including other squads)

Siege Specialist

Siege Specialist25G

Unlocks when Assault, Breacher, Marksman and Medic all reach level 30. Rotate classes so the gear achievements below progress alongside the levels. Play Infantry or higher so the missions also count toward Lift Outta Hell.

Turn It Up to 11

Turn It Up to 1115G

As Assault, execute 50 enemies while they are stunned by the Sonic Disruptor. Stun a group, then finish stunned enemies with executions rather than shooting them dead. The count is cumulative.

I'm All Amped Up

I'm All Amped Up15G

As Breacher, keep the Adrenaline from the Injector going for 30 seconds straight. Look for mods that extend the Injector's uptime as you level Breacher, then trigger it during a long, busy fight and keep it active.

Spotted and Slotted

Spotted and Slotted15G

As Marksman, tag 1,000 enemies with the Pulse Drone. Every enemy pulsed counts, so deploy the drone whenever it is off cooldown. Big waves fill this fast.

Down, but Not Dead

Down, but Not Dead15G

As Medic, revive 250 downed squadmates with the Stim Vaporizer. This only counts downed (DBNO) players, not COG tag revives. It is the slowest of the four gear counters, so play plenty of Medic. Medic also covers the next achievement.

Who Loves Ya, Baby?

Who Loves Ya, Baby?15G

Revive 20 players from other squads. Squads cross paths during missions, and the Stim Vaporizer's area revive picks up other squads' downed players. Head toward fights where another squad is struggling.

Ongoing Mission Goals

Lift Outta Hell

Lift Outta Hell15G

Complete 50 missions on Infantry or higher. Rookie is the tier below Infantry and does not count. The mission itself completes if just one squad member extracts. But the achievement says "Complete and Survive," and nobody has confirmed whether a mission where you personally died counts. Safest route: stay alive and board the Raven yourself every time. Short Blitz missions on Infantry are the fastest way.

Best I Can Do Is a Pizza Party

Best I Can Do Is a Pizza Party15G

Complete 100 Horde Siege Secondary Objectives, such as defusing explosives, killing high-value targets, collecting intel or delivering a Power Core to another squad's R.I.G. Take every one you pass.

Stacks, On Stacks, On Stacks

Stacks, On Stacks, On Stacks15G

Spend 150,000 Energy at Supply Caches in total, on any difficulty. Energy is a shared squad pool earned from kills and objectives, but each player spends their own share. Buy equipment, weapons and perks every mission instead of saving Energy.

Like a Boss

Like a Boss15G

Complete 25 Invasion Events. These are announced to every squad: a Corpser or Brumak with escorts that applies a modifier, such as blocking extraction or disabling caches, until it is beaten. Every squad that takes part shares the reward. When one is announced, go and fight it.

Form-Up!

Form-Up!15G

Unlocks when you claim the Legendary perk from a Perk Cache. That perk only goes to the first squad to interact with the cache. Squads that arrive later get an Epic perk, which does not count. Perk Caches are random COG Resupply drops and don't appear in every mission. They also attract Locust. When one drops, rush your squad to it before the other squads get there. Any difficulty counts.

This Is My Rifle

This Is My Rifle15G

Unlock every Horde Siege Weapon Mod. Mods unlock along the class tracks and then have to be bought with Weapon Parts. Weapon Parts are only kept if your squad extracts. Mods are shared across classes. Spend Weapon Parts on mods as they unlock, and this finishes alongside Siege Specialist.

I WILL MASSACRE YOU

I WILL MASSACRE YOU25G

Kill 50,000 enemies in Horde Siege, on any difficulty. This builds up across all of the above. Long Horde-playlist missions give the highest kill counts.

I Didn't Hear No Bell

I Didn't Hear No Bell15G

This method comes from the community solution published on TrueAchievements, which used Infantry with random teammates. It is not officially confirmed.

Buy Stim Grenades, then wait near a Supply Cache, away from the objective, until all three squadmates are dead.
Pick up all three COG tags.
Get downed close to the cache.
While downed, deliver all three tags in one trip. The achievement should unlock as the respawn timer starts.

Timing precautions: use a Stim Grenade if you go down before you have all three tags. Dead players respawn on their own if you take too long. An active Invasion Event can lock Supply Caches, so wait until none is running.

Allfather

Never Fight Alone

Never Fight Alone15G

Extract from an Allfather mission with all squadmates alive. Nobody has confirmed whether bot squadmates count. Safest route: play with three friends, all on max-level classes, and keep everyone alive through extraction. A Medic is close to essential. Allfather has one-shot enemies and harsh modifiers, so leave this until your classes are level 30.

Versus

Versus is 4v4 with fixed loadouts. The modes are Team Deathmatch, Conquest, Demolition and Crucible, played across six maps: Outpost, Battleship, Park, Precinct, Market and Skyward.

The Player vs Bots playlist (under Versus, then Social) is the easiest way to do the mode- and map-specific achievements. Bot matches give XP and count toward achievements. Whether bot kills count toward the 25,000-kill total is not confirmed yet, though an early report says they do. Check the achievement's progress after your first bot match. Players also report the bots are very accurate even on lower settings, so expect a real fight.

Map and Mode Achievements

Days Since Last Accident: 0

Days Since Last Accident: 015G

Unlocks when you kill an enemy on Battleship by dropping a hanging bomb on them. The map has two hanging bombs, each linked to a green button. Open the map to find them. Go to Versus, then Social, then Player vs Bots, set the bots to the lowest difficulty, and play until Battleship comes up. Camp by a button and press it when a bot walks under its bomb.

Somebody Set Up Us the Bomb

Somebody Set Up Us the Bomb15G

In Demolition, plant the bomb at an enemy site and let it explode without being defused. Your team has no respawns until it goes off, so plant it somewhere you can hold, then guard the bomb. Against bots this happens naturally.

It Only Game, Why You Heff to Be Mad?

It Only Game, Why You Heff to Be Mad?15G

Win a Conquest match without the enemy team scoring. In Conquest, zones only score once a team has held them long enough. Keep the enemy off every zone for the whole match. This is most realistic against bots.

The Kill Grind

HEY NOW, YOU'RE AN ALL STAR…

HEY NOW, YOU'RE AN ALL STAR…25G

Get 25,000 kills in Versus. This is the largest grind in the game. Count on playing hundreds of matches. No in-game kill counter has been found, so judge progress from the achievement's progress tracker. Favor the modes and playlists where you get the most kills per hour. An early report says kills in the Player vs Bots playlist count toward the 25,000, which would make it the efficient route, but this isn't confirmed. Check the achievement's progress after your first bot match before you commit to it.

Player Level and Final Goals

Player XP comes from Horde Siege, Versus and Weekly Challenges. The campaign gives very little. The level cap is 100. At 100 you can Re-Up, which resets your Player Level to 1 with a reward. You can Re-Up four times, for five runs of 1 to 100. Re-Up resets Player Level only. Class levels are tracked separately and are not expected to reset, though no player has reported testing it. Do the Weekly Challenges every week. XP was rebalanced at launch so that Horde Siege and Versus level at a similar rate. All your Horde and Versus grinding feeds this anyway.

Re-Ups and Final Achievements

Field Service

Field Service15G

Reach Player Level 100 and Re-Up for the first time.

Got Your Wings

Got Your Wings25G

Required: reach level 100, then perform each of the four available Re-Ups yourself, one every time you reach level 100 again. There is no fifth Re-Up. After the fourth, reach level 100 once more on the final run and claim the wings when the game offers them. Reaching 100 without pressing Re-Up never counts. That is 500 Player Levels in total.

Dead Serious

Dead Serious85G

Unlocks when all four conditions are met: 100% Campaign on Insane, 25,000 Versus kills, max Player Level, and all four classes at max level. The first, second and fourth conditions match For Whom the Bell Tolls, HEY NOW, YOU'RE AN ALL STAR… and Siege Specialist. What exactly counts as max Player Level is not defined, and it is not confirmed whether it means level 100 on your current run or the final Re-Up behind Got Your Wings. Since you need Got Your Wings anyway, finishing that route covers it, but don't assume the two unlock together. If Dead Serious hasn't unlocked once everything else is done, check each of the four conditions separately. Some Steam text shows 10,000 Versus kills, but the Xbox description says 25,000, and you need 25,000 for HEY NOW, YOU'RE AN ALL STAR… anyway.

Collectibles

Reference

This tracker lists every campaign collectible and Hard Case, grouped by act. Entries follow route order. Ticking an entry here is your own checklist only; the War Journal and the achievements are what the game actually tracks.

Collectibles: Act 1

War Journal collectibles count toward Memories From E-Day and the 100% requirement of For Whom the Bell Tolls.

Hard Cases: Act 2

36 in the game

Hard Cases count toward Relax. I'm the Map. and the 100% requirement of For Whom the Bell Tolls. They have no in-game names, so each is listed by location, with its reward where known. A top-left alert and Tac-Com (LB) reveal nearby cases. They are not marked from earlier runs, and reloading a chapter respawns them, but cases found on a replay are reported to still add to the War Journal's per-act count. Sweeping them during the main run keeps cleanup small. Where a reward below doesn't single out one case, check every location in that chapter.
