Real Survival mode, known in Japan as the "Real Survival Mode"(リアル・サバイバル・モードRiaru sabaibaru mōdo), is a feature in the 2002 remake of Resident Evil and its HD remaster. It is unlocked after completing "Once Again...", which is itself unlocked after completing the game once, saving it, and starting a new game from a Cleared Save file. In this mode, the game is set to Hard difficulty, auto-aim does not work, and the item boxes are no longer interconnected.
