that allows Super NES controllers to be used with the 3DO. Light gun The only light gun released for the 3DO was the Gamegun, a product of third-party developer American Laser Games. Despite this, no fewer than 10 games with light gun support were produced for the system. Most of these were arcade ports from American Laser Games (including Mad Dog McCree), but Virgin Interactive and Digital Pictures also released 3DO light gun games. The 3DO Gamegun uses the same design as the Gamegun released for the Sega CD: an orange "Old West" revolver.

Other popular titles included Total Eclipse, Jurassic Park Interactive, Gex, Crash 'n Burn, Slayer, Killing Time, The Need for Speed, Road Rash, and Immercenary.
