Fill your Ice Meter. Beat the Demon using Polar Blast.
Here are the passwords for each level.
Enter the ''Password'' Option and input the code:
Play the first level, when you get to Scorpion beat him. Do the fatality (F,D,F HP -one step away) and grab the scroll. Run to the rope and climb up. Pause the game, and exit. Go to the password screen and enter the code: RGTKCS. Fight the enemies and get caught. You will then see an F.M.V. with Scorpion's spirit instead of Shinnok. You must then fight Scorpion a second time, as the boss.
