There's more going on on Chatroulette than just dudes showing off their junk. Well, not MUCH more, but occasionally something like this comes along.

The brilliant people at RealmPictures created an actual, real-life FPS with an amazing twist - each round was controlled by an individual, randomly chosen user on Chatroulette. Not only that, but it was an impressively thorough FPS, with weapon drops, zombies galore, and an FPS protagonist voice that Nolan North would approve of.
