When Microsoft was gearing up to release the Xbox 360, one of the biggest questions was whether or not the console will feature backwards compatibility of Xbox games. While it took Microsoft quite some time to make the announcement, Mortal Kombat: Deception was on the initial list of games to be backwards compatible and playable on the Xbox 360.
However, no news has been released on when Deception is going to return to the compatibility list and it may look like it may never make its return. Peter Moore, Corporate VP of Microsoft's gaming interests, mentioned that "nobody is concerned anymore about backwards compatibility" in an interview with Kikizo Games. Moore also mentioned that Microsoft has actually "under promised and over delivered" on the backwards compatibility front for the Xbox 360.
It appears that Microsoft is no longer focusing on backward compatibility with the Xbox 360 and it might well mean that Mortal Kombat: Armageddon has practically no shot at being playable on the Xbox 360.
