Tis true that it is impossible, the Xbox360s hardware is no match for the Ps3s and can't handle a game of this quality, the graphic engine this game was made with was specifically made for the Ps3's hardware and nothing else. This game would have to be dumbed down to a maximum amount to put on a 360 and all the 3D effects on walls, floors, rocks, faces, everything would look flat and less detailed, the gloss in everything such as metals, guns, and other shiny objects would have to be toned down aswell and would look awful. Thats why this was made to be a Ps3 exclusive, because the Xbox360 CANNOT handle it.
