Back 4 Blood’s First Expansion is coming in April

Tunnels of Terror comes with a multi-floor dungeon, Ridden Hives, set underneath the game’s central gather area, Evansburg. Players will work their way through its various levels, facing a new kind of mutated ridden: warped ridden. Along with new weapons and characters, Ridden Hives will also feature warped chests and skull totems that are said to play into the subterranean theme. Though the specifics have yet to be revealed, it seems the warped ridden are confined to the dungeon, so players who haven’t purchased the expansion won’t need to look out for them in the regular campaign.

Tunnels of Terror will introduce two new characters—Sharice, an axe-wielding firefighter, and Heng, a tough as nails, no-nonsense restaurateur—along with a new co-op activity called Ridden Hives, set across seven different dungeons below the town of Evansburgh that are filled with a new type of enemy called Warped Ridden. (“Ridden” is Back 4 Blood’s name for zombies.) The expansion will also feature eight new character skins, seven legendary weapons and 12 new weapon skins, new cards, and more.

The release of Tunnels of Terror will also bring a free update for all players that will add a new difficulty setting called No Hope—details about the setting weren’t provided but you can probably pick up the gist of it based on the name alone.

Turtle Rock noted in the launch date announcement that all players in a Back 4 Blood party will have access to the content in Tunnels of Terror as long as at least one person has purchased it. The studio also promised that “there will be no microtransactions of any kind, cosmetic or otherwise, added to the game as part of this expansion or any future content update.”

Turtle Rock also revealed that Back 4 Blood is a legitimate hit, notching up more than 10 million players since its October 2021 release and becoming the best-selling new game property of 2021.

“To achieve such a milestone in the short time since the launch of Back 4 Blood is a historic event for our studio and this franchise,” Turtle Rock Studios president and general manager Steve Goldstein said. “As we look ahead, we’re excited to keep the momentum going with our upcoming expansion, Tunnels of Terror, which will offer more cooperative content for fans to continue cleansing the world of the Ridden.”
