Midway (and its successors) have always been fans of releasing various updates and ports of Mortal Kombat games. Mortal Kombat: Unchained is one of the most worthy handheld MK games, featuring all of the content from console versions of MK: Deception as well as 6 extra characters, 4 of which are exclusive. Unchained is one of the better titles to add to your PSP library.
