Seriously, I don't understand how this flew over so many heads. I mean, I totally understand that the humour didn't land for everyone, but the whole point of the game was to be a humorous counterpoint to the super-edgy grimdark tone that so many other shooters of the time were immersed in.
While other games were using swearing to appeal to the angry teen demo, Bulletstorm was pushing bad language past reason and into the realm of the ludicrous. You weren't supposed to be sitting there thinking "Oh man, yeah, dicktits, sick burn."
