Co-op
Aliens: Fireteam Elite 2 co-op — four-player squads, cross-platform play and voice chat, AI squadmates, team composition and how to find a fireteam at launch.
Introduction
Aliens: Fireteam Elite 2 is built around four-player co-op, expanding the original three-marine fireteam to four for deeper team-based play. Cross-platform play and cross-platform voice chat are available at launch, so a friend on PC can squad up with a console player without friction. If you prefer to go it alone, AI-controlled squadmates fill the other marine slots. Team composition matters more than ever — balancing a Medic for healing, a Machinist for turret support and damage dealers for crowd control is the difference between a clean clear and a wipe. Our co-op guides cover matchmaking, party systems, roles, revive mechanics and the best ways to find a reliable fireteam.

Core Mechanics
Co-op in Aliens: Fireteam Elite 2 works through a party and matchmaking system that supports four players. The fireteam assembles in the USS Endeavor hub, where squads can coordinate loadouts before deployment. Cross-platform play and voice chat are enabled at launch, letting mixed-platform squads communicate without workarounds. Revives are a core mechanic — when a marine goes down, a teammate must revive them, and managing revives under fire is a major part of high-difficulty play. Solo players are joined by two AI squadmates that follow and fight, but they do not coordinate focus fire, so solo runs require a more self-sufficient loadout. The official Steam community, Discord and Reddit are the best places to find a fireteam before launch.
Advantages
Four-player co-op deepens team play compared to the original three-marine fireteam, allowing more balanced and specialized compositions with dedicated healer, lane-control and damage roles. Cross-platform play and voice chat at launch remove the biggest barrier to squadding with friends across platforms, so nobody has to buy the game twice to play together. The AI squadmate system makes the game playable solo without a long queue, and the community tools — Steam community, Discord and Reddit — make finding a reliable fireteam straightforward. The co-op guides also cover communication habits and revive discipline that keep random squads alive through the hardest missions.
Challenges
Four-player co-op means a bad teammate is more costly, and high-difficulty missions with friendly fire punish uncoordinated squads more severely than in the original. AI squadmates are weaker than human players, making solo runs harder and less flexible. Cross-platform play is confirmed at launch but the exact matchmaking region behavior and party invites between platforms have not been fully detailed pre-launch, so squads should be prepared for occasional platform-specific quirks during the first weeks after release. Co-op guides will be updated with confirmed matchmaking behavior once the servers are live. Re-check co-op guides after launch for confirmed matchmaking and party behavior.

Quick Tips
Use voice chat even in random squads — a single call-out of a Siren or a Crusher charge can save the whole team from a wipe, and consistent communication is what separates a balanced four-player squad from four solo players sharing a mission. Clear communication turns a random squad into a team that clears content together.
When friendly fire is enabled, announce before firing a Signature weapon; a misplaced rocket launcher shot can down a teammate in the middle of a swarm, and a quick heads-up gives everyone time to clear your line of fire before you pull the trigger. Clear communication turns a random squad into a team that clears content together.
Always have at least one teammate watching the revive — downed marines snowball into wipes, and a Medic Sustain build makes revives far more forgiving, so designate a reviver before the fight starts and keep them out of the front line. Clear communication turns a random squad into a team that clears content together.
