In a statement, developer Turtle Rock said it needs more time to make the co-op shooter “the best it can possibly be at launch”. Turtle Rock added there will be an open beta this summer. “Back 4 Blood is everything I’d want from a new Left 4 Dead,” wrote our Martin in his hands-on Back 4 Blood preview. Turtle Rock is the team behind Left 4 Dead and Evolve. Back 4 Blood returns to the Left 4 Dead concept, where you and three friends fight against seemingly endless hordes of undead. In the video above, Ian Higton, Aoife Wilson and Zoe Delahunty-Light play Back 4 Blood for an hour.
