I know that this isnt a game, but it was so great I thought it deserved mentioning. If you have ever seen "Happy Tree Friends" then you know what im talking about.
This is the most demented cartoon I have seen in a while. go to Happytreefriends.com and check em out!!!!
P.S. If you are disturbed by any gruesome acts, don't watch this. It isnt for the light of heart. Seriously.
