Or you can just ask us staff since we've played it lol
The triggers can now be used to cycle through your command deck (and still use the D-pad like with the PSP version if you are more comfortable with it that way)
The camera has been mapped to the right analog stick and automatically set in inverse camera mode (or at least I believe so because it was really confusing turning the camera and it wasn't going the way I needed it to, this is probably something that can be changed in settings)
All face buttons remain the same. Overall it feels a lot better than playing it on the PSP, manly because your fingers hands aren't being cramped by the PSP's awkward shape...although if you are a person with big hangs and hate the Dualshock 3, this probably won't be good for you. xD
