Mortal Kombat vs. DC Universe (MK vs. DC) is a crossover fighting game from Midway Games and Warner Bros. Games. The eighth game in the Mortal Kombat series, MK vs. DC was released on November 16, 2008. MK vs. DC contains characters from both the Mortal Kombat franchise and the DC Universe. Its story was written by comic writers Jimmy Palmiotti and Justin Gray. This was the last title to be developed and published by Midway Games, as it filed for Chapter 11 bankruptcy and sold the rights to Mortal Kombat to Warner Bros. (also owner of DC Comics). This was also the first console MK game to have an unrestricted rating by the ESRB as well as the first MK game to be published by Warner Bros. Games.
The story of MK vs. DC takes place after Raiden, Earthrealm's god of Thunder, and Superman, hero of Earth, repel invasions from both their worlds. An attack by both Raiden and Superman simultaneously in their separate universes causes the merging of theMortal Kombat and DC villains, Shao Kahn and Darkseid, resulting in the creation of Dark Kahn whose mere existence causes the merging of the universes that if continued would result in the destruction of both universes. Characters from both universes begin to have a flux in power, some becoming more powerful and others becoming weaker.
MK vs. DC was developed using Epic Games' Unreal Engine 3 and is available for the PlayStation 3 and Xbox 360 platforms. It is the first Mortal Kombat title developed solely for a seventh generation console. The majority of its ratings range from 7.5/10 to 8.5/10. Most reviewers agreed that MK vs. DC was entertaining and made good use of its DCU license; however, a lack of unlockable features as opposed to past installments and toned down finishers garnered some criticism.
