Great space-themed survival game for 4 players. Simple but deep exploration and production system with a lot to explore. Family friendly.

Old-school beat-em-up game for 2 players with goofy moves, sounds and dialogue straight from the cult film series. Play Remote and local.

Played 4-player co-op. Nice old-school action- RPG. Story's a bit uninteresting, but the combat is meaty and the loot if plentiful.

The DMZ mode is full of great sneaky co-op combat VS NPCs and other players. Up to 3 players.

Fun and deceptively intense 4-player co-op. Keep building a train track before the train gets there.

An excellent zombie world sandbox simulator, with many settings to tweak. Play solo or with up to 16 players.

A fun MMO-style survival/action game - play as a viking in a fantasy world. Play with friends to build explore and conquer! Max 10 players.

Not strictly co-op, but you can host private dedicated servers and invite your friends to form a clan. Max 40 players.

Parkour meets zombie survival in this stunning-looking first-person shooter. 4 player co-op.

An interesting co-op survival game where you do your own thing, but the game subtly pushes you to play together. Comparable to Don't Starve Together. Max 8 players.
