At the tittle screen, open "Killer Codes" and enter: A, C, A, B, A, B, B, A, C, A, B, A, B, B, A, C, A, B, A, B, B, A, C, A, B, A, B

Players one and two must enter these button combinations on the vs. screen with the A, B, and C buttons respectively. The number indicates the times you must press each button.

First you must go to the options menu. Then set your controller down and wait until you hear a laugh. Wait ten more seconds and it will go to exit by it self. Then start a tournament pick your fighter. Let the computer beat you then when the continue screen pops up press start on controller 2 but when it asks Mortal Kombat 2 on 2 or 8 player tournament go to Mortal Komabt and press start on controller 1.

On one of the "Endurance" or boss squares play the game but lose. Right before your opponent kills you, press Start on the second controller. At the Mortal Kombat screen, press Start on the first controller. Choose a character and start a game. When you play you will move above that square. This sometimes works on normal players but sometimes it doesn't.

Note: This trick always works if you select Shao Kahn. You will then play against several different characters endlessly. As a bonus, every time they win they will do a finishing move on you.

Plug in a second controller, but play a one-player game. When you lose, hold Down on both controllers and your opponent will kill you with a fatality or a brutality.

Select the robot Smoke on character select screen. Then, before the fight screen comes up, hold High Punch + Low Punch + High Kick + Low Kick. Continue to hold these until Shao Kahn announces the round. (A six-button controller might help...)
