About the game
You are a soldier in a fictional modern war. In the co-op mode called Checkpoint, your squad fights through a chain of objectives against waves of computer soldiers. You capture a point, hold it while the enemy counterattacks, then push on to the next one. There is no story campaign.
Up to eight of you play online on PC, PlayStation or Xbox, and crossplay is on by default. Everyone picks a class and builds a loadout. Bullets kill fast and your health does not regenerate, so you move slowly and cover each other. If you die, you sit out until the squad captures the next point.
The game also has PvP, so check that you joined a co-op mode. It is serious and loud, and it suits a group that likes to talk through each push.

Backs Crossplay, Crossplay between.
- Crossplay: The support site says crossplay is on by default and lets Xbox, PlayStation and PC players match together.
- Crossplay between: With crossplay off, a console player matches only their own console family, and cross-generation play is still possible. The families are named, not each console, so PS4 and Xbox One are read from that.
