Attic of the Underdogs

One of the most graphically violent games ever made, XEvil is probably one of a handful of games that manage to be this offensive and controversial and get away with it. The game features an incredibly addictive gameplay that will have you laugh like a maniac while blowing up enemies in imaginative ways. Liberal references to the software industry also makes this a great game for any programmer who feels too much like Dilbert and has to let off some steam - preferably against hapless human victims ;)
