Rogue fuckin' Warrior. Was curious to try this game out to see if it's as bad as the reviews say it was (average of around 20%)... and holy shitballs it comes close.
The main character is voiced by Mickey fuckin' Rourke
who also sings this awesome song during the credits http://www.youtube.com/watch?v=vEBfKe6BXCQ
and every other word is a swear word of some sort. It's so bad that I want to play more of it to see how bad it gets, which shouldn't take too long seeing as how the single player is about 2-3 hours long.
If you can ever get your hands on this game, get it just for Rourke's lines.
"It's a total goat fuck" and "God damn cock-breath commie motherfuckers" are two of my favourite ones so far.
And there's the butt finisher.
