Sometimes you need to know when to quit, and developer Turtle Rock is making a good move with its Left 4 Dead clone.

Back 4 Blood is finished, after a year-plus of being active since launch. The Left 4 Dead co-op FPS clone will not be getting new DLC and content moving forward, with Turtle Rock Studios getting to work on the next big thing (that isn’t hopefully going to be another Evolve). Here’s what the studio wrote on its official website.

“What an amazing year 2022 was for us.

First off, we wanted to thank all of you for making Back 4 Blood what it is today. With three expansions—Tunnels of Terror, Children of the Worm, and River of Blood—we’ve travelled on a fantastic adventure together beyond the walls of Fort Hope. This phase of our war against the Ridden now comes to a close.

Turtle Rock Studios is actually pretty small for a studio making AAA games. We don’t have quite enough folks to continue working on Back 4 Blood content while we spin up another game—yes, another game! Given this, it’s time for us to put our heads down, get back in the lab, and get to work on the next big thing.

You’ll also still find us hanging out in the subreddit(opens in new tab) and on Discord(opens in new tab), as well as our official Twitter(opens in new tab), Instagram(opens in new tab), Facebook(opens in new tab) and website(opens in new tab) because we love interacting with you and talking about our games.”

The game will still be available on PC, Xbox, PlayStation, Xbox Game Pass, and PlayStation Plus Extra/Premium platforms and services.
