Are you talking about the Demo or the Retail because as far as I could tell I could not re map my keys.
Having A and D turn my character instead of strafing means its made for a controller.
and seeing as they don't use the "click on the bad guy to attack the bad guy" anymore there is no reason to have right click move the character anymore unless its just more movement keyed to a controller joystick.
No there is no PC controls for the Demo
