Perfect Dark Zero 100% guide

• Nothing requires Xbox Live. Every multiplayer achievement can be earned offline in local games with bots and a second controller. No achievement needs ranked play, wins, or a rank.
• Online status (as of 2026-10-04): Xbox 360 online services remain up after the July 2024 Marketplace closure. Do not rely on matchmaking; the full multiplayer route can be completed offline.
• Co-op is required for six achievements. Local split-screen co-op works, and it can be done alone by holding one controller in each hand or parking player 2. A friend makes it much easier.
• Nothing is permanently missable. Every mission can be replayed on any unlocked difficulty.
• Minimum campaign runs: three. Dark Agent needs a full Perfect Agent clear first, and you need a Dark Agent clear in both solo and co-op. The main route is co-op on Perfect Agent, then solo on Dark Agent, then co-op on Dark Agent. For the three-run minimum, Perfect Agent must be completed in co-op first.
• Dark Agent is locked until you finish all 14 missions on Perfect Agent. A co-op Perfect Agent clear unlocks Dark Agent in both modes; a solo Perfect Agent clear unlocks it only for solo. The unlock is per profile: a partner only earns Dark Agent achievements if their own profile has Dark Agent unlocked.
• Difficulty clears stack. A campaign clear on a given difficulty also awards every lower difficulty clear in that mode, so a Dark Agent clear awards all four clears for that mode.
• The multiplayer grind is the bulk of the time. Expect several long sessions of near-idle bot matches for the 1,000-count achievements.

• There are 14 missions, numbered 0 to 13: Datacore Demolition, Nightclub Stakeout, Subway Retrieval, Rooftops Escape, Mansion Infiltration, Laboratory Rescue, River Extraction, Trinity Infiltration, Trinity Escape, Jungle Storm, Temple Surveillance, Outpost Rescue, Bridge Assault, and Arena Showdown.
• "Completed" difficulty achievements need all 14 missions finished on that difficulty in that mode. Missions do not have to be done in one sitting.
• Solo and co-op completions are tracked separately. You need a full solo set and a full co-op set.
• Weapons only join your Armory loadout permanently if you finish a mission holding them. The first mission (Datacore Demolition) never unlocks weapons. Unlocked weapons stay available on every difficulty. This is how you take the Plasma Rifle into Dark Agent.
• Checkpoints thin out as difficulty rises. Checkpoint reports conflict on Dark Agent. Some guides report one in Datacore Demolition; others report none. Do not plan around having a checkpoint: a death restarts the mission (not the campaign). Players also report no regenerating health and no shield pickups on Dark Agent.
• Achievements pop after the mission ends. Always leave through the debrief screen, and on Arena Showdown let the ending cutscene play out, rather than quitting to the dashboard.
• Keep your own tally of which missions you have cleared on each difficulty and mode. Don't rely on the mission select screen to show it.

Perfect Dark Zero is one of the Xbox 360 titles in Rare Replay. This guide covers the full 1,000 Gamerscore list, which goes well beyond what Rare Replay's own stamps ask of this game.

Start a split-screen co-op campaign with your main profile as player 1 and set the difficulty to Perfect Agent. Agent, Secret Agent, and Perfect Agent are all selectable on a new save; only Dark Agent is locked.

Why co-op Perfect Agent first: it awards the co-op Agent, Secret Agent, and Perfect Agent clears straight away, and it is the only Perfect Agent clear that opens Dark Agent for both solo and co-op. A solo Perfect Agent clear only opens solo Dark Agent, so starting solo would cost an extra co-op Perfect Agent run.

Keep your main profile as player 1 for every co-op run. It is unconfirmed whether a second local profile also receives the Perfect Agent clear or the Dark Agent unlock, so a friend playing for their own achievements should give their profile its own Perfect Agent clear.

For two-controller play, sign a second profile in on the second controller. Whether a guest controller works for campaign co-op is not confirmed, and each profile keeps its own weapon loadout.

If you are playing alone with two controllers, keep player 2 tucked into a safe corner whenever possible, and bring them along at points that need both players. Some doors and switches need both players, and the Datacore Demolition lift needs both players on it before the mission ends. Some enemies, especially in Mansion Infiltration and Outpost Rescue, will hunt down an idle player 2.

Play the missions in order. In-order play is the simplest way to make sure all 14 are covered. Keep a tally as you go.

Mission-fail conditions to keep in mind on every run:

• Nightclub Stakeout: shooting a civilian fails the mission. During the opening Audioscope sequence, don't kill all three starting guards; leave at least one alive until the first enforcer has been identified and the mission advances.
• Rooftops Escape: Jack dying fails the mission.
• Mansion Infiltration: disarming the SuperDragon-carrying door guards fails the mission.
• Trinity Escape: friendly fire on your allies can fail the mission.

Mansion Infiltration and Trinity Infiltration also use conversation prompts. In Mansion Infiltration the security radio and the front-door intercom have separate prompts, and two of them sound almost the same but need different answers, so match the exact line.

Security radio:

• "Hello? You OK?" → Threaten
• "Whoa, it must be freezing out there! You OK?" → Charm
• "Hi there bud, control here. Anything I can do for you?" → Charm
• "Is this maintenance?" → Bluff

Front-door intercom:

• "Hello? You OK out there?" → Charm
• "Everything alright out there?" → Charm
• "Is that you, Lee?" → Bluff
• "What is it now?" → Bluff
• "I was sleeping..." → Threaten

For any line not listed, go by the speaker's tone: Bluff when they mention Lee or maintenance, Charm when they are friendly or concerned, and Threaten when they are angry or scared.

In Trinity Infiltration, answer Father's lines exactly:

• "Welcome friend..." → Charm
• "Father, at your service" → Threaten
• "System instability..." → Bluff

A wrong answer doesn't fail the mission, but it sends a large group of guards, including tower snipers, after you. In Mansion Infiltration the radio can also be bypassed with the antenna tower switch or the Demokit.

The single most useful thing to take out of this run is the Plasma Rifle, which has an invisibility secondary that makes later Dark Agent missions far easier. Finish these missions holding the weapons below so they unlock in your Armory loadout:

• Plasma Rifle: Temple Surveillance is the best-documented source. After you plant the tracking device, Mai Hem's cloaked Phantoms attack, each carrying a Plasma Rifle. Take one from a fallen Phantom while at least one other is still alive, because the mission ends the moment the last Phantom dies. Bridge Assault is a backup source, from the cloaked female soldiers who attack after you cross the bridge.
• RCP-90: Jungle Storm. Its secondary fire highlights enemies.
• Hawk: Trinity Infiltration (a loading-dock crate) or Jungle Storm. Recommended for Rooftops Escape on Dark Agent.
• ViBlade: Mansion Infiltration, on the pedestal in the laser room. Bank it there rather than relying on Zhang Li's sword in Arena Showdown.
• SuperDragon: Outpost Rescue.
• Shockwave: on the ground near the start of Bridge Assault.
• Rocket Launcher: Bridge Assault. One comes from a soldier on the rocky ledge above the blocked tunnel. More are in armory crates that need the Locktopus gadget, and a gadget can only be chosen once that mission has been beaten on that difficulty in either mode.

If player 2 is a signed-in second profile, have them finish holding the key weapons too, since they need gear for the co-op Dark Agent run. A player can drop a weapon for the other to pick up before the mission ends.

Before starting, check your Armory loadout for the Plasma Rifle. If it is missing on your profile, replay Temple Surveillance solo on Agent and finish the mission holding a Plasma Rifle. It is a short detour and it changes the whole run.

Dark Agent is the hardest content in the game. Don't plan around having any checkpoints, and expect no regenerating health or shield pickups, much more dangerous enemies, and very little room for mistakes. Strategies that hold up across most missions:

• Use cover constantly. Peek, fire a burst, return to cover.
• Use the Plasma Rifle's cloak to sneak past enemy groups that you do not need to kill. It is especially strong in Jungle Storm, Temple Surveillance, and Bridge Assault. The cloak also lets you cross the fragile wooden walkways in Temple Surveillance.
• The RCP-90's secondary fire tags enemies through walls, which helps you plan routes.

Play in order where you can. If one mission is a wall, skip it and come back. Any mission can be picked on Dark Agent once it is unlocked.

Set up co-op again with your main profile as player 1. Your solo Dark Agent experience carries over directly, but co-op adds extra enemies in places, including a second Mai Hem in Mansion Infiltration, and some doors and endings need both players.

With a friend, this is often easier than the solo run because enemy attention is split between two players. Alone with two controllers, it is the toughest part of the list: keep player 2 parked out of enemy sight and bring them forward only when needed. Every mission has been completed this way, but Mansion Infiltration, Temple Surveillance, Outpost Rescue, and the boss fights need patience.

If player 2 is using a separate profile, make sure it also has the Plasma Rifle and other key weapons in its loadout. Only profiles with Dark Agent unlocked earn credit from this run.

Every multiplayer achievement is a lifetime counter that builds across all games, so progress carries over between sessions and nothing needs to be done in one match. Local bot games and split-screen games all count. The backward-compatible build includes the May 2006 title update, which added bots to DarkOps modes.

Rules for every session:

• Use local play (not Xbox Live). A second controller is accepted in local games.
• Follow each participant count exactly. The farming setups below generally use 16 total participants on the small variants, counting every human controller: up to 15 bots with one controller, or 14 with a second controller.
• Bot personalities matter. Bully hunts whoever has the fewest kills, which makes a parked second controller a perfect decoy. Judge hunts the leader. Feud picks a random target each spawn. Vanilla, Venge, Prey, Ghost, and Random are also available. Strong teammates and weak enemies make most sessions quick.
• Every match needs an end condition: a time limit, a points limit, or the appropriate round limit. A match that can never end banks nothing.
• Avoid idling. Move every controller once after the countdown. In round-based modes with a parked second controller, move it once each round, or the match ends early. Matches that only last seconds need no input.
• Let every game finish. Progress banks and achievements pop on the post-match screen. Quitting mid-game throws that match's progress away. Continuing from the results screen is fine.
• Restrict weapons with Custom weapon slots and the "Disallowed weapons" advanced option to progress the counters you want.
• There is no reliable way to see your totals offline. Keep a rough tally of games and rely on the achievement pops as checkpoints. If a milestone doesn't pop when expected, play one more full match unchanged, then check the limits, bot count, idling, and your role.
• No map pack is required. Every session below uses base-game maps.

Every Deathmatch scenario game (Territorial Gains, Capture the Flag, Killcount, Team Killcount) counts toward Played Deathmatch Games. Every DarkOps game (Infection, Sabotage, Onslaught, Eradication) counts toward Played DarkOps Games. Do the sessions in the order below. The short sessions early on confirm the counters are working before you start the long grinds, and the 1000-game sessions at the end of each half only need the remainder.

Start with these short, quick wins.

Killcount kills only count in Killcount, but the Expert Kill counters count in every mode. This session pairs the Killcount counter with explosive kills, since the Plasma Rifle's primary fire counts as an explosive weapon.

Explosive kills are counted by weapon. The Plasma Rifle's primary fire, the Rocket Launcher, frag grenades, and mines are reported to count. Grenade-launcher secondaries, Caltrops, the Demokit, and the Shockwave are unconfirmed, so don't rely on them.

Both setups here use a second controller as a decoy, so they use 14 bots. Set Team Killcount on Desert in its small size with these shared settings:

• 14 bots on Agent difficulty with the Bully personality
• Bot teams set to humans versus bots
• You and the second controller together on Team Dark
• A 100-point limit, plus a time limit as a safety net

Park the second controller in the safe spot by the rock near the big cliff. Get a few early kills so the controller always has the fewest kills, and the Bully bots will stream toward it.

All the Deathmatch sessions so far have counted, which comes to about 41 games if you followed the setups above. Finish whatever is left with very short games.

DarkOps modes add a second counter, games played, which climbs in every DarkOps session.

Both modes use a second controller as the opposing team, with no bots. Move the second controller at least once per round, and keep it connected, or the match ends early.

Save this for last. Rounds Survived only counts Eradication rounds, so about 1,000 Eradication games remain however many other DarkOps games you have played. Those same games finish the DarkOps games counter along the way.
