Turtle Rock Studios, the developers behind Evolve and the Left 4 Dead franchise, has announced that they’re working in partnership with Warner Bros. Interactive on a “next-gen cooperative FPS” entitled Back 4 Blood.
Something of a spiritual successor to Left 4 Dead and its sequel, which were originally published by Valve, was announced via a news post in the Turtle Rock forums, and will be “designed from the ground-up as an original, premium title and marries the best of what made the co-op zombie shooter so successful with new features and state-of-the-art technology.”
