Many "MK9 PSP" downloads found on forums and third-party sites are actually modded versions of Mortal Kombat: Unchained (the PSP port of MK: Deception ) or Mortal Kombat: Shaolin Monks . Modders often swap character skins and menus to make the game look like MK9. While these are impressive technical feats, they are not the actual 2011 game. The gameplay mechanics, fatalities, and graphics will be from the older PS2-era titles.
