Quite possibly Mortal Kombat: Armageddon's most controversial but unique new addition to the series is the Kreate-A-Fatality system. For the first time ever, standard character specific Fatalities have been abandoned and this time the player gets to choose how their victims die. Just how is this done exactly? Read the following for a detailed step-by-step walkthrough.
The Fatality Levels below determine how well you performed your Fatality. Refer to this list once you understand the KAF system and successfully receive a Fatality message on your screen.
There are different moves depending on the position of your opponent. The different possible positions are as follows.
FINISHERS - Last move, make it good!
Some moves can only be performed under certain conditions such as you holding or beating someone with their own arm - you have to rip it off first. These will be noted.
Additionally Boss characters (Motaro, Shao Kahn, Goro, Kintaro, Moloch) have their own set of moves that ignores all others.
Moves are listed with the current position of the victim ontop. Therefore a move that reads...
BEHIND
F, F, 1
...means that you will need to be behind your opponent to perform it.
