Typically valued around $6000, the Sega R-360 does just what it says..moving the strapped-in player in full 360 directional spin on a two-axis movement.
More details and video…
For safety it has a harness similar to a roller coaster harness, two seatbelts which attached to the harness, and an Emergency Stop Button. An attendant monitors the game-play from a tower stand, which also has an emergency stop button.
Two games are compatible for the cabinet: G-LOC and Wing War.
