Download and Install Mortal Kombat Vs DC Universe PS3 - The Ultimate Guide for PS3 Gamers
According to interviews, the characters were chosen for their popularity, and for parallels between them from both universes.[3] Ed Boon, creative director of Mortal Kombat vs. DC Universe and co-creator of the Mortal Kombat franchise, has said that some of the characters' abilities, especially those from the DC Universe, had been toned down to make them balanced within Mortal Kombat vs. DC Universe. For example, Boon specifically mentioned that Superman became vulnerable because of magic.[28][29] Boon revealed that two new characters were developed as downloadable content, Quan Chi from Mortal Kombat and Harley Quinn from DC comics but had been discarded.[30] He had also hinted earlier at the prospect of Kung Lao and Doomsday being downloadable characters.[31]
The game's story involves an unintended merging of both Earthrealm (the setting for Mortal Kombat) and Earth (the setting for DC Universe) as a result of the simultaneous destabilization of both Shao Kahn's portal (as the result of a blast by Raiden) and Darkseid's boom tube (as the result of a blast by Superman). In addition, this merging causes numerous power fluctuations with the combatants of both universes (adding new strengths and vulnerabilities), violent "kombat rage" outbursts (which causes "good" characters to fight among themselves), and both Shao Kahn and Darkseid merge into a more powerful form (Dark Kahn).
