Blood Code: At the story line screen, press: A, B, A, C, A, B, B. Cheats: At the "Game Start" screen press: D, Up, B, B, A, F, D. Reptile Code: Start a single-player game and fight your way to the Pit. If a silhouette appears across the moon, battle at the Pit without using the block button, completing a Double Flawless and then doing your character's Finishing Move. This means that only Sub-Zero, Johnny Cage, and Rayden can fight Reptile, as they don't use the Block button as part of the Finishing Move. Reptile fights with either Sub-Zero's or Scorpion's moves and moves two times as fast as either of them. Beat him, and you get an extra 10 million points!
