Unlock Evil in survival mode
At the character select screen, input the following: up, up, down, down, left, right, left, right. The character named Evil will then be unlocked for usage. The character disappears after quitting the game, so the code has to be re-entered when the player wishes to use him again.
Completing the conditions for certain medals will unlock characters. These characters can be used in survival modes and have different stats, however these differences do not carry over if they are used in story mode.
