Bought this originally for my iPod Touch and now double dipped and picked it up on the iPad.
This game is great on each device, but I think it really shines on the iPad. The graphics are gorgeous and the controls seem better suited on the iPad since you can more accurately aim thanks to the larger screen.
I really wish with all of these simultaneous releases between iDevice and ipad that there would be some way to transfer saves through the cloud or some other means. I don't mind playing through on both of them, but it'd be nice to play at home on my iPad and then continue playing on the go.
Beautiful game Gameloft! I think they've pretty much mastered FPS on these iDevices.
