Back 4 Blood is a cooperative first person shooter from the creators of Left 4 Dead, following a team of survivors fighting through hordes of mutated creatures called the Ridden, using a card based system to customize their abilities before each run.

An AI game director shifts enemy spawns and throws corruption cards into play, keeping repeat runs through each campaign unpredictable for squads working together. Its blend of team based shooting and deck building progression carries forward the spirit of classic zombie survival co op shooters.
