Question: is xcom 2 multiplayer co op?
Answer: XCOM 2 co-op mod available now. Only for two, but 12-player co-op should be on the way. ... Tactical Co-Op adds (tactical) co-op to the turn-based strategy game, and while it's only playable by two people currently, the modders say they're "waiting on Firaxis to approve code" for 12-player battling.
