Mortal Kombat II Cheats

This works in both 1 and 2 Player modes. During a match on The Portal stage, if you get the 'Toasty!' guy to appear, quickly press Down + Start. If done correctly, you will be transported to Goro's Lair to fight Smoke.

This only works in 1 Player mode. During the fight that is right under the '?' box, defeat your opponent by only using Low Kick. After the fight, you will be transported to Goro's Lair to fight Jade.
