I love how Epic always acts like Bulletstorm is "their" game and talk as if they made it.
People Can Fly made it. You know, the folks who made one of the best FPS's of all time, Painkiller?
I guess since it's so bad People Can Fly don't want to be connected with it and have let CliffyB take full credit for it and its 4 hour long single player and lack of any real MP modes.
