Squad up

Crossplay & Co-op — how squads actually work

Everything documented about playing together: cross-platform support, the jump to four-Marine fireteams, and the AI teammates who fill empty seats. Sources: Wikipedia, GamingBolt, official site.

Cross-platform play at launch

The sequel supports cross-platform play and voice chat at launch across PC, PlayStation 5 and Xbox Series X|S (Wikipedia; official site). This was one of the most-requested features in the community's pre-launch wishlists (r/AliensFireteamElite), so PC and console friends can finally share a fireteam.

Four Marines, not three

Fireteams now field up to four players instead of the first game's three (Wikipedia). The extra seat changes squad math: you can run a dedicated support without sacrificing a damage slot, and compositions get meaningfully deeper — see squad composition.

AI teammates: Alpha, Beta, Gamma

Empty seats are filled by AI allies (Wikipedia), and GamingBolt documented their distinct loadouts:

GammaShotgun / close range

Solo players effectively get a balanced three-bot squad: Beta covers long lanes, Gamma watches your personal space, Alpha flexes. It's a genuine upgrade for players who found the first game's bots indistinct.

Matchmaking anxiety, answered

The recurring forum worry — "will I find games?" — is exactly what crossplay addresses by merging the PC/PS5/Xbox pools. Add AI backfill and you can always play, even off-peak. If you'd rather vet teammates first, the Steam discussions hub is the game's busiest LFG spot.
