NZGamer: Bulletstorm isn’t ground-breaking in any way. It felt like a delicious goulash of past shooters like Duke Nukem, Unreal Tournament, Serious Sam and Borderlands. But I still found myself laughing shamefully, cringing sympathetically and then replaying levels over and over to unlock a new kill achievement or just to let off some steam. It’s the best kind of guilty pleasure. It’s human nature to want to experiment.
