I have a few questions about this game, I am thinking of purchasing this [http://www.amazon.com/Wireless-Run-N-Drive-Gamepad/dp/B000WHEGWE/ref=sr_1_22?ie=UTF8&s=electronics&qid=1196977578&sr=1-22] controller mainly because the controller can be mapped at will. I know that the controller does not support motion controls whic brings me to my actual question. Is it possible to use the sticks to handle aiming grenades and walking on logs etc.? While we are at it what are the button options already present in the game?
