Leaving aside the inter-dimensional diversions of the most recent Mortal Kombat vs. DC Universe, the game's unusually involving single-player story begins after the events of Mortal Kombat: Armageddon, but then returns to the events of the first three games to revisit the series' original lore. Gaining a trans-temporal awareness, the enigmatic thunder-god Raiden is central to the plot, but gamers take the roles of several different combatants as they progress through the campaign. In all, over two-dozen characters are playable in this edition of Mortal Kombat, each uniquely modeled and individually animated. Multiplayer fighting is thoroughly supported, in both same-console and online options, with a selection of competitive and cooperative modes.
