Hidden Tofu Message
Near the end of the game in the Laboratory, you will reach a computer that you have to enter passwords into in order to progress through the game. If you enter the password "MOLE" from the original game, you will actually hear Tofu from Resident Evil 2 on the computer screen. Strangely, this only works on Easy Mode for some reason.
