How co-op works
Co-op ranges from authored two-player scenarios to large community missions, with infantry, vehicles, aircraft, logistics, and long-range fire coordinated across open terrain. Eden missions are multiplayer-ready, while a Zeus game master can alter objectives, units, and threats live; separate modes also support competitive warfare.

The depth comes from layering infantry, armor, helicopters, and artillery into combined-arms engagements. Teams plan insertions, call for fire support, and navigate dynamic objectives that sprawl across kilometers. Communication is essential: calling out contacts, coordinating movement, and managing logistics separate successful squads from chaotic wipes.
Both online co-op and LAN play are supported, along with competitive PvP modes that pit teams against each other in large-scale battles. Matches can stretch for hours, rewarding persistence and tactical discipline. The result is some of the most communication-heavy teamwork in any multiplayer shooter.
