Crispy

Frosty

When playing as either Sub-Zero (Classic or Unmasked), freeze your opponent while their health is in Danger and Dan Forden will pop out to say 'Frosty!'.

Play as Noob Saibot

To play as Noob Saibot, you must be playing against another human opponent. Pick Kano and, immediately before round 1 starts, hold Back + Low Punch + Low Kick + High Punch + Block. If done correctly, Kano should explode into Noob Saibot.

Play Forever

This code will allow you to continue playing Ultimate Mortal Kombat. The only catch is, you cannot die. When you beat the game, choose the goodie that lets you fight Ermac. Win the first round, and lose the second round on purpose. Win the third round and perform a mercy (hold Run, down, down, down, release RUN), and then perform your characters animality. You will be taken to the ''choose your destiny'' screen. Keep repeating the process, and you can rack up hundreds of wins.
Note: This was fixed in version 1.2.
