Pac-Man VR
Pac-Man VR is a 1996 video game by Virtuality set in the Pac-Man universe. The game featured play in a 3D environment from a first-person perspective. The game did not change any gameplay mechanics of the original game, except adding a multiplayer feature. The game cabinet itself was expensive, as was play which cost five dollars for five minutes. The cabinet was a 2000 SU series model, where the player stood in a ring set at the waistline. The player could turn his head and a tracking system built into the glasses would detect  it and turn Pac-Man's head in the game. Crouching and standing tall were also allowed and movement was done with a joystick. An adaption for the SU-3000 Systems was released, later on, making Pac-man VR the only non-shooting game ever released for SU-3000 systems. The promotional page that was originally on Virtuality's web site (which no longer exists), describes the game:
