Resident Evil 2: DualShock Version

Several months after the original release of Resident Evil 2, a second version of was released known as the DualShock Version. As the title suggests, the game was modified to incorporate support for the vibration function and analog control of the PlayStation DualShock controller. The main addition is a new unlockable minigame, "Extreme Battle". The objective is to reach the police station from the underground laboratory and retrieve four anti-biohazard bombs located throughout the station. There are four playable characters and three difficulty settings. The Extreme Battle became a standard feature for subsequent versions of the game.

There are also some minor additions, such as ranking screens for the Hunk and Tofu minigames, a Rookie difficulty setting for the main game, as well as a "USA version" mode in the Japanese version, based on the North American version's default setting and a new cheat code that grants the player unlimited ammo for all weapons.
