The Back 4 Blood story takes place after a catastrophic outbreak where most of humanity has either been killed or infected by the parasitic Devil Worm. Hardened by unspeakable events and emboldened to fight for the last of humanity, a group of apocalypse veterans called the Cleaners have rallied to take on the infected horrors known as the Ridden and reclaim the world. Back 4 Blood features thrilling, dynamic moment-to-moment gameplay and highly variable, customizable action to keep players coming back for more. 

Back 4 Blood includes a four-player cooperative story campaign in which the Cleaners must fight the Ridden and work together to survive increasingly challenging missions. Players can team-up online with drop-in and drop-out co-op to fight the ever-evolving Ridden threat together or play the campaign solo with three AI teammates. The game also features competitive multiplayer in which participants can play with or against friends in online PvP that supports up to eight players and teams take turns playing as both the Cleaners and the horrific Ridden. 

Back 4 Blood can be played online with a squad of four players or solo with up to three AI teammates. The game will also support up to eight players in online PvP (person versus person) multiplayer.

Warner Bros. Games and Turtle Rock Studios unveiled the launch trailer for Back 4 Blood – Expansion 2: Children of the Worm, the next major downloadable content (DLC) for the first-person co-op zombie shooter.

The video showcases brand-new story campaign elements that put players into an epic showdown with a new adversary known as The Cultists, a deranged group of humans who fight for the rise of the Ridden.

Children of the Worm will feature a brand-new story campaign that puts players into an epic showdown with a fierce new enemy threat. To help combat this unknown adversary, the expansion will introduce “Prophet” Dan, a gun toting, self-proclaimed preacher of the end times, who joins the growing list of playable Cleaners in their effort to save humanity. Children of the Worm will also include eight exclusive character skins and 12 exclusive weapon skins, along with new weapons, accessories, and cards.

Children of the Worm is scheduled to release on Aug. 30 as part of the Back 4 Blood Annual Pass, Back 4 Blood: Deluxe Edition, Back 4 Blood: Ultimate Edition, or via standalone purchase. 

Children of the Worm follows the previously released Back 4 Blood Tunnels of Terror DLC expansion, which is available now.

Back 4 Blood's innovative Card System is a new rogue-lite feature that enhances your experience with each playthrough, ensuring every gameplay session is dynamic, intense and feels unique.

Players can easily jump right into the action by choosing a pre-made default deck or dive into the Card System’s vast customisation options to create their own fully personalised deck of cards.

Back 4 Blood takes advantage of an adaptive A.I. known as the Game Director, which works behind-the-scenes monitoring the actions, health, and choices of players. It responds accordingly by changing environmental conditions, adding obstacles, and unleashing special Ridden mutations through Card System modifiers known as Corruption Cards. Players can change up the gameplay by utilising specific cards to strategise against the Game Director, from amplifying equipment to reloading weapons, as they take on hordes of enemies in their path.
