Back 4 Blood features 8 survivors, known as Cleaners. The first four cleaners were introduced in the reveal trailer: Walker (man in the hat), Holly (woman with the red hair), Evangelo (man with the fluffy hair), and Hoffman (man with glasses). The remaining 4 cleaners are Doc (woman physican), Jim (man in hunting outfit), Karlee (punk woman), and Mom (middle-aged woman). Any four of the eight Cleaners can be selected in a game. Each Cleaner has different abilities and perks.
The annual pass (which is included in the Deluxe and Ultimate editions of the game) will include new playable characters, both Cleaners and playable Mutation Ridden for PvP.
You are at the center of a war against the Ridden. These once-human hosts of a deadly parasite have turned into terrifying creatures bent on devouring what remains of civilization. With humanity's extinction on the line, it's up to you and your friends to take the fight to the enemy, eradicate the Ridden, and reclaim the world.
There are currently three modes: Coop Campaign played through several Acts, Swarm which is a Player versus Player (PvP) mode, and Training which is Coop Campaign but solo with bots. Cleaners upgrade their characters with Cards in both all modes. In Swarm when playing as the Ridden team, the Zombie Mutation System is used to upgrade the Common ridden as well as to power up the playable Ridden classes.
