Gareth, a disabled gamer, uses his chin to control the mouse buttons for movement, but Dead Space 2 didn't allow him to remap the controls for his play style. He expressed his disappointment on the Overclockers forum, then took his case to the EA forums asking the developers to consider his request. A subsequent petition has resulted in 25,419 signatures so far.
Visceral has heard the outcry and is doing something about it. Executive Producer Steve Papoutsis told Joystiq that the team is "passionate" about getting the fix done, and said he's "very proud of the people on the Dead Space 2 team for coming in today and jumping on the fix first thing." He says the patch will include various PC fixes along with key binding, and the developer will announce a release date once it's been tested.
