Back 4 Blood is a cooperative first-person shooter video game developed by Turtle Rock Studios, the developers of the Left 4 Dead series. The game is set in a post-apocalyptic world overrun by zombies, where players take on the role of “Riders,” a group of survivors tasked with fighting against the zombie and uncovering the source of the outbreak.

The gameplay is similar to the Left 4 Dead series, with players working together to fight off waves of zombies while also completing objectives and rescuing survivors. Players can choose from a variety of characters, each with their own unique abilities and weapons. The game also features a dynamic “Director” AI system, which adapts the difficulty and number of enemies based on the players’ performance.

Back 4 Blood features a single-player campaign mode, which tells the story of the outbreak and the Riders’ efforts to uncover the source and stop it, along with a multiplayer mode, where players team up with others to take on the zombies together.
