Microsoft has recently updated their Xbox 360 backwards-compatibility list and has added
Mortal Kombat: Deception. Deception was originally on the list, but was removed due to gameplay and graphical issues.
Since
Mortal Kombat: Armageddon uses the same gameplay engine as Deception, hopefully it will be added to the backwards-compatibility list in the not to distant future.
