Laughs aside, the gunplay has quite a satisfying kick too. Or hucking frag grenades into a crowd of living dead only to have the ensuing sinew-showers drench friends. All too often, I found myself grinning over utterly absurd sights, like Sleeper Ridden sitting comfortably in meaty wall-mounted cocoons suddenly springing to life then pinning a teammate to the floor. That surprisingly pleasant attitude pervades combat in Back 4 Blood as well.
