Back 4 Blood surpasses 10 million players, ‘Tunnels of Terror’ expansion launches April 12

Back 4 Blood‘s first major downloadable content expansion, “Tunnels of Terror,” will launch on April 12, publisher Warner Bros. Games and developer Turtle Rock Studios announced.

Additionally, the companies announced that over 10 million players have played Back 4 Blood, which Warner Bros. Games describes as “2021’s best-selling new IP on consoles” based on United States tracking from The NPD Group.

“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,” said Turtle Rock Studios president and general manager Steve Goldstein in a press release. “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.”

Here is an overview of the expansion, via Warner Bros. Games:

When the Back 4 Blood “Tunnels of Terror” expansion arrives on April 12, teams of up to four friends can jump into an all-new co-op activity known as Ridden Hives, where they will explore seven different dungeons full of labyrinthine tunnels below the depths of Evansburgh that are infested with a new Ridden type, Warped Ridden.

To claim exclusive loot and rewards only offered in Ridden Hives, players must outmaneuver and overcome the daunting new Warped Ridden, including the landmine-setting Urchins, monstrous Shredders, and damage-dealing Rippers. The new Warped Ridden variants are also playable in PvP Swarm mode.

The upcoming expansion introduces two new playable Cleaners—Sharice, an axe wielding firefighter, and Heng, a tough as nails, no-nonsense restaurateur.

Also included in “Tunnels of Terror” are eight exclusive character skins, seven new legendary weapons, 12 new weapon skins, new cards, and more.

The expansion will coincide with the release of the “No Hope” difficulty setting, a free update adding an extra level of challenge for elite players.

Please note, all playable content included in the “Tunnels of Terror” expansion will be accessible by all players in a party as long as one player in that party has purchased the expansion.

Additionally, 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.

Back 4 Blood is available now for PlayStation 5, Xbox Series, PlayStation 4, Xbox One, and PC via Steam and Epic Games Store, as well as via Xbox Game Pass.
