About the game
The Ridden are people taken over by a parasite, and they have overrun most of the world. You play a Cleaner, one of the survivors who fight back from one safe room to the next. Before each run you build a deck of cards that changes your health, damage or gear. The game plays its own cards against you, like fog or armored enemies.
Up to four of you play online, and each Cleaner gives the team a different bonus. You pick each other up when downed and can hand over ammo. Bots fill empty slots when you play solo, though they are poor at reviving. A 4v4 mode lets one side play as the Ridden.
The tone is light, with jokes between Cleaners and the odd grenade that splatters a friend. It plays best with a regular squad, and crossplay works between PC and consoles.
