Here are some codes for MK MYTHOLOGIES:

Ten Urns of Vitality: NXCVSZ ( Gives you ten urns on
your inventory.)

1,000 Lives: GTTBHR ( Pretty much what it says.)

Credits View: CRVDTS ( Lets you view the credits.)

Ultimate Cheat: ZCHRRY ( Takes you to the last level
and gives you all the experience points. Oh yeah, when
you die, just before the game loads, hit L1 to fight Quan
Chi and L2 and R2 to go to Shinnok. Well, thats all I know!
See Ya!
