This game is really meant to be played on a controller. The game does support gamepads however it does not provide a preset layout and requires you to do it yourself. I can't find a FAQ or manual for the controls on the 360/PS3 at the moment so was I hoping if anyone using a gamepad can provide a proper layout (console style) here for us with gamepads to use.
So far I'm using a basic layout that I've made up for my gamepad (Logitech Rumblepad 2) mainly based on Burnout Paradise (for PS3).
Hey dude I have the solution for you. I made a profile for NFS Most wanted 2012 using the Logitech Profiler which lets you play the game with your Logitech gamepad. I have a Rumblepad too so I can assure you it will work. Instructions are included.
