The spiritual successor to Valve's Left 4 Dead series, Back 4 Blood follows the same, zombified formula, where you and three other players must survive against a horde of infected as you race to a series of safehouses.
A new feature in Back 4 Blood is the use of cards to build your character. At the start of each level, players need to build a deck with cards that adjust various elements of gameplay, such as modifying the player's health, damage, and stamina, to give them an edge against the AI. The AI director also has some cards to play with too, called Corruption cards, which can be used against the player to hinder their progress. The AI director can spawn extra enemies, activate a fog effect, and increase the size of the horde, all to put a stop to the survivors.
Back 4 Blood will feature a 4 player co-op mode and 8 player PvP. It will release for the PC, Xbox One, PlayStation 4, Xbox Series S and X, and the PlayStation 5.
