Speaking in a notice on the official website, the studio more or less stated the three expansions – Tunnels of Terror, Children of the Worm, and River of Blood – are the only DLC to expect for the game. The notice reads that since Turtle Rock is a “pretty small” studio, it doesn’t have “quite enough folks to continue working on Back 4 Blood content” while it creates another game. That said, the game will continue to operate, it’s just the developers will be a “bit quieter in the short-term.” Back 4 Blood is a first-person co-op zombie shooter from the creators of the Left 4 Dead franchise that pits you against the Ridden, the once-human hosts of a deadly parasite. You can also play against friends in PvP by becoming a Cleaner, one of the immune survivors with special perks, or, switch sides and play as the Ridden. It is available for PC, PS4, PS5, Xbox One, and Xbox Series X/S. It is currently offered on PlayStation Plus Extra and Premium tiers and available as part of Xbox Game Pass.
