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 announced the next Back 4 Blood downloadable content (DLC) expansion, officially titled River of Blood, scheduled to release on Dec. 6, 2022, as part of the Back 4 Blood Annual Pass, Back 4 Blood: Deluxe Edition, Back 4 Blood: Ultimate Edition, or via standalone purchase.

River of Blood will feature a brand-new story campaign with an enthralling five-map mission that has players traveling upriver, stopping at different points along the way to collect supplies and take on new enemy threats. To better assist the Cleaners with this mission, the expansion introduces Tala, a former cultist outcast now turned Cleaner who is accompanied by a Ridden companion named Jeff, a friendly Tallboy that can be summoned to assist the team. Jeff causes ultimate mayhem when called upon via whistle by Tala or other Cleaners on her team. River of Blood also includes eight exclusive character skins and 12 exclusive weapon skins, along with new weapons, accessories, and cards. 

Additionally, Trial of the Worm will be available as a free update for all Back 4 Blood owners and will release alongside the River of Blood expansion. Trial of the Worm is a cooperative PvE mode where players determine their path down a four-map chain while earning Supply Points along the way. Players can add Corruption Modifiers or choose the more vigorous paths to increase difficulty and boost the amount of Supply Points rewarded. Those looking for a challenge or a more customized difficulty can work towards completing Trial of the Worm with a high score to earn a top spot on the online leaderboard.

Lastly, the Back 4 Blood Holiday Event returns from Dec. 6, 2022 through Jan. 4, 2023 where players can enjoy festive decorations in Fort Hope, listen to holiday music at the jukebox, and grab holiday skins, emblems, weapon skins, and sprays. More details will come at a later date.

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.
