Warner Bros. Games and Turtle Rock Studios have launched the next major Back 4 Blood downloadable content (DLC) expansion, River of Blood. The latest expansion features a brand-new story campaign and a new Cleaner, Tala, a former cultist outcast who is accompanied by a friendly Ridden Tallboy companion known as Jeff.

Players can use the whistle found in-game to summon Jeff as long as Tala is on the team. River of Blood also includes eight exclusive character skins and 12 exclusive weapon skins, along with new weapons, accessories, and cards. The River of Blood expansion is available now as part of the Back 4 Blood Annual Pass, Back 4 Blood: Deluxe Edition, Back 4 Blood: Ultimate Edition, or via standalone purchase and follows the previously released Children of the Worm and Tunnels of Terror DLC expansions.

Additionally, Trial of the Worm, a new cooperative PvE mode, is available now as a free update for all Back 4 Blood owners. Trial of the Worm allows players to 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 awarded. Those looking for a challenge or a more customised 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 in-game Holiday Event returns today and will be available through Jan. 4, 2023, with festive decorations in Fort Hope, holiday music at the jukebox, and emblems, weapon skins, sprays, and holiday skins to obtain, including reindeer antlers for Holly, an ugly sweater for Mom, elf ears for Evangelo and more.

Back 4 Blood is a first-person co-op zombie shooter from critically acclaimed developer, Turtle Rock Studios, available now for Xbox Series X|S, Xbox One consoles, PlayStation 5 and PlayStation 4 consoles, and PC. 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.
