The game supports the Rumble Pak and the Expansion Pak. Other features include an item-randomizer, violence control (allowing players to change the color of the blood), first-person controls and new unlockable outfits replacing the ones from the previous versions. The most prominent was a series of additional in-game documents known as the "EX Files" that connected the plot of the game with the other games in the series (including the then-unreleased Resident Evil Zero). While it was the only port of the game that did not feature the "Extreme Battle" mode, it did contain a slew of console-exclusive features. Released on Novemin North America, this version was ported by Angel Studios (now Rockstar San Diego) and features the most drastic changes. The graphics remain the same as in the original version.

The Japanese release also features a USA mode, which is similar to the North American normal mode. Also included with the DualShock version was a cheat code that could be entered to receive infinite ammo for all weapons and a grade for the 4th survivor scenario. In "Extreme Battle" mode, players have the ability to choose four characters (Leon, Claire, Ada, or Chris Redfield) to fight several enemies in different levels with a certain amount of time. Released on Augin Japan, the DualShock version also adds many more features such as an Arrange Game, which includes Rookie Mode (much like easy mode but with the Gatling Gun, MAC-11 SMG and Rocket Launcher in your inventory at the start of the game) and "Extreme Battle" mode.

Months after the PlayStation version came out, Capcom released the PlayStation DualShock version, which contains support for the new analog and vibration features of the then new DualShock controllers.
