Campaign
Aliens: Fireteam Elite 2 campaign — the 15-mission story across four biomes at Storr Boon’s Mining Facility on LV-558, with difficulty, friendly fire and mission rewards.
Introduction
The Aliens: Fireteam Elite 2 campaign drops your four-marine fireteam onto LV-558 at Storr Boon's Mining Facility, where smarter Xenomorphs and hostile synthetic androids swarm in overwhelming numbers. Fifteen missions carry you through four distinct biomes, from industrial corridors to alien-infested depths, with the USS Endeavor serving as the hub between deployments. The story unfolds through mission objectives, environmental storytelling and enemy encounters, and the campaign is built to be replayed — difficulty settings, friendly fire, Challenge Cards and mission rewards all change the experience on a second or third run, giving a full co-op campaign with real progression and a clear reason to keep playing.
Campaign Biome Overview
| Biome | Setting | Threat Profile | Rewards |
|---|---|---|---|
| Industrial Core | Refinery corridors and maintenance tunnels | Drone swarms and early synthetic patrols | Standard weapon and cosmetic unlocks |
| Foundry Depths | Deep processing chambers with heavy machinery | Strikers, Exploders and Crusher pressure | Augments and weapon traits |
| Alien Hive | Biological growth overrun facility tunnels | Hive swarms, Sirens and Harbingers | Signature weapon parts |
| Surface Ruins | Exposed mining plateau with open sightlines | Wardens, Bulwarks and long-range synth fire | Endgame gear and Challenge Cards |

Core Mechanics
The campaign is structured around a hub-and-spoke loop. Between missions you return to the USS Endeavor, where vendors sell gear and consumables, cosmetics are equipped and squads are prepared before the next deployment. Each of the 15 missions takes you deeper into one of the four biomes, mixing combat encounters with progression checkpoints. Difficulty scales the enemy AI and, at higher levels, enables friendly fire in exchange for better rewards. Challenge Cards can be slotted before a mission to add perks or debuffs that increase the payout, giving veterans a reason to revisit completed missions and chase higher-difficulty clears and their associated cosmetics and gear unlocks.
Advantages
The 15-mission structure gives a full-length co-op campaign with real progression, so there is always a clear next objective and a reason to keep playing. The four biomes provide strong visual and mechanical variety, ranging from tight industrial corridors to open surface sightlines, and the hub adds a social layer where squads can regroup, restock and gear up between deployments. Replayability is built in through difficulty settings, friendly fire and Challenge Cards, so the campaign remains relevant even after the story is complete and becomes the natural training ground for the harder challenges of horde mode. The campaign section also links each mission to the class, weapon and ammo recommendations that suit its biome, so you always know how to prepare.
Challenges
Because the game has not launched, exact mission layouts, collectibles and boss fights are written from the announced 15-mission, four-biome structure rather than live play. Pre-launch walkthroughs cannot yet include every hidden item or spawn point, and some story details, including the rumored Dagger Company storyline, are still being confirmed by the developer. The campaign is designed for four players, so solo runs with AI squadmates are noticeably harder and require more careful loadouts, ammo discipline and positioning. Mission pages will be updated with confirmed layouts and collectible locations as players verify them in-game. The campaign section will grow as players confirm the exact mission structure in the live game.

Quick Tips
Visit the USS Endeavor vendors between every mission — Challenge Cards and consumables bought there are often the difference between a clean run and a wipe on higher difficulties, and checking the vendors after each mission keeps your loadout fresh for the biome ahead. Planning your loadout for the biome ahead keeps you from getting caught flat-footed mid-mission.
Equip a Challenge Card even on missions you have already beaten; the increased payout is worth the extra risk, and cards teach you how to handle debuffs before you need them in horde mode where mistakes are punished much harder than in the campaign. Planning your loadout for the biome ahead keeps you from getting caught flat-footed mid-mission.
When friendly fire is enabled, call your shots — a misplaced rocket launcher shot can down a teammate, so reserve Signature weapons for enemies that are clearly away from allies and let rifle fire handle targets that are mixed into the squad. Planning your loadout for the biome ahead keeps you from getting caught flat-footed mid-mission.
