Mortal Kombat 11: Ultimate is a 2020 fighting game developed by NetherRealm Studios, available on PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PC, and Google Stadia. It serves as the complete edition of Mortal Kombat 11, bundling all previously released content into a single package. The game includes a 37-character roster, adding Rain, Mileena, and Rambo as new fighters. Two story campaigns form the narrative core, both centered on a time-manipulation conflict in which Earthrealm's defenders must prevent the villain Kronika from resetting history. The campaigns explore shifting alliances and personal loyalties among the cast as the stakes escalate to a threat against existence itself. Core fighting game mechanics combine with the expanded roster and story content to represent the fullest version of the base release.
