Mortal Kombat: Deadly Alliance Tips & Tricks

You can perform a fatality from anywhere on the screen. Y,B,X,A represent the attack buttons and when they must be pressed. Press the stance change button when the screen says FINISH HIM/HER to change into your fatality stance or you'll have to figure out the distance range manually.

Use Raiden and his staff then push Black repeatedly. You might need to step back to a decent distance for this to work. His fighting style is random and will fight differently often.
