Music is subtle and unobtrusive, while guttural zombie gurgles and roars will keep you on edge. Audio cues for special characters don't induce panic like you'd hope, however. Remember when a tank or witch turned up in Left 4 Dead? It's not quite the same in Back 4 Blood.
A very nice-looking game, Back 4 Blood succeeds in generating a wonderful atmosphere of foreboding during its levels, taking you to cool locations like police stations, lakeside docks, abandoned gas stations, and graveyards. Every now and then, there's the odd glitch, but we encountered nothing major.
Immediate and instantly enjoyable if you know how to play a first-person shooter. The card system, with its helpful cards and gameplay-altering 'Corruption Cards' help mix things up a bit, lending a little extra depth to proceedings. Crucially, Back 4 Blood is good, solid fun.
The lack of solo progression is an unsightly blot on an otherwise superb game, leaving lone wolves out in the cold. But, if you can stand to play with random people or (better still) rally around a team of friends, then there are countless hours of entertainment to be had.
Dig in for a tough old time if you want to bag every one of Back 4 Blood's achievements – completing every act at the rock-hard 'Nightmare' difficulty is a requirement, for starters. And, there are secrets to be found, as well as some creative tasks to complete. A good mix of objectives, but it's no picnic.
