Like their previous games Left 4 Dead, Left 4 Dead 2, and Evolve, Turtle Rock Studios’ Back 4 Blood (Xbox Series X, Xbox Series S, Xbox One, PlayStation 5, PlayStation 4, PC) is a first-person shooter that’s meant to be played co-op. But unlike those games, Blood is also clearly made for people who’d like to play solo. Not to the same point a Call Of Duty sequel or Halogame, where there’s a dedicated story-driven campaign, but certainly enough that you can still have a good time even if you don’t play well with others.
