To perform a fatality you must be at the end of a match and wait for the game to say “Finish Him!” or “Finish Her!”. You need to stand at the correct distance, so pay attention to which range is noted next to each Fatality. Close Range means to stand adjacent to the enemy, Mid Range means to stand half a screen length, and Long Range means to stand a full screen length.
The input needs to be entered quickly, which can make some combinations particularly difficulty. Thankfully, there is a Practice Fatality mode that you can enter within the Single-Player menu to get used to entering the codes quickly.
Note that while the below commands assume that you are on the left side of the opponent facing right. If you are on the right side facing left, then flip the Left and Right inputs.
