Nova planing to destroy New Earth, after recording all of it's knowledge and trying to make the knowledge more valuable, then travels to the other universes and do the same to them. The Avengers try to prevent this from happening but Nova frees Apocalypse from the Phantom Zone to stop them and in the battle with they get sent to the Netherrealm Studios universes and team up with the Mortal Kombat heroes and villains to stop the destruction of the Multiverse.

The rules for the game as fallowed.

The Street Fighters would have knowledge of alternate universes (Do to the events in the Marvel vs Capcom game series), the Avengers and Mortal Kombat would have trouble believing each other at times, leading to them fighting each other (Spiderman would be the most untrusting of the Mortal Kombat, especially of Scorpion). Because of their mastery of Ki "Life Energy" the Mortal Kombat are able to match the Marvel characters in speed, strength and power, (This is way Raiden could kill Apocalypse and Shao Kahn can hurt Hulk).

There would be three sub-plots in the game; (Spiderman and Scorpion would fight, with Scorpion turning in a flame demon and turns into "Inferno Scorpion" and tries to kill Spiderman.), (Doomsdays goes on a rampage and Akuma challenges him to combat and the Avengers and Kombatants have to stop Raiden form killing him or Apocalypse well return even more powerful then before), (Shao Kahn attacks Hulk in a decomposing clone body and tries to steal his and becoming a god).

The playable characters in the game as fallowed, (28 in all).
