We have an X-Box here at work, in the lounge, and one of the games sitting in the locked cabinet is 'Sneakers', which was apparently made for traumatizing small children.
Most of the game is hide-and-go-seek on rails, where you run around the house (or whatever) trying to find rats. Then, once you've found all the rats with the same color hat, they jump you and you have to beat them up. The fights are kind of silly, with various-hatted rats making tiny punches, while you and your friends punch back. When enemy mice get knocked out, food appears which restores your health.
But if you take too long, or are careless, one of your friends might get knocked out. And then they die. And remain dead FOR THE REST OF THE GAME. They even edit them out of the cut-scenes.
Majorly creepy. Especially with how cheery the remaining mice are, acting as if their now-dead friends never existed. O.O
