I doubt its a xbox verson of zombiU given a large amount of its controls are based on WiiU's tablet like controller such as the scan function, where you look though the screen on the controller to look for and mark things of interest on your map(basically a survivor version of detective mode from the arkham games), or the no pause separate screen for your inventory ... would have to be recoded or removed... My guess it is ether a wholly new game or the older one rehashed..
(and for the record I have the game and the system, never beat the game its fairly hard.. not dark souls hard but still fairly diffcult)
