The new Mortal Combat for the Wii will have several new modes.

-Kreate a Fighter
Players can make their own character with over 100 different combinations. They can make the character at least 14 different classes which include humans, Tarkatans, Mercenaries, Black Dragon Members, Ninjas, Retro Ninjas, Geisha Assassins, etc. The clothing must be unlocked and is not preset. They have unique fighting styles in stance,moves, and the buttons that you attack with. You will need to purchase some of these with coins.
Kreate a Fatality

Also new to the series is the ability to create a Fatality. These custom fatalities are a constant series of commands that players input until the Fatality ends. This method of performing Fatalities replaces the character-specific Fatalities of previous Mortal Kombat games, where gamers would simply enter one input and view the Fatality cinematically. As the player adds each input, less time is allowed for further inputs and some moves cannot be repeated. There are ten levels that can be achieved with Kreate a Fatality (novice gamers average 4 or 5 inputs, achieving a "Bloody Fatality" or "Mortal Fatality", while an expert may reach 11 inputs and achieve an "Ultimate Fatality"). It should be noted that custom-created fighters lack the ability to transition the opponent into another position during these Fatalities.
