113 co-op horde shooter games on Steam with co-op or multiplayer, ranked by how many people are playing right now and how well they review. Part of Shooter.
Horde shooters are the reliable Tuesday-night pick: no story to catch up on, a mission that fits in forty minutes, and the satisfaction of a wall of enemies falling over. Helldivers 2 is the current standard, Deep Rock Galactic the most beloved (Rock and Stone), Left 4 Dead 2 the one that still fills lobbies fifteen years later. Warhammer 40,000: Darktide and Space Marine 2 bring the melee, Killing Floor 2 and World War Z bring the zombies, and Call of Duty's Zombies modes bring the nostalgia. Two players is a real way to play all of these — most scale difficulty to the squad size. Ranked by players online first, so you always see which of them has a busy matchmaker tonight.
