Cyber Troopers Virtual-On is a 3D action video game developed and published by Sega. A robot-themed shooter and fighter, it was developed on the Sega Model 2 hardware and released on arcades in January 1996 (or December 1995) before ports to the Sega Saturn that year and to Windows the next year. Initially the game was to be released under the title "Virtual-On" in Japan and "Cyber Troopers" in North America, but ultimately these two names were combined into a single title for both regions.

There were also two-player online versions of the game released in America and Japan for the Sega Saturn using the NetLink and XBAND services respectively. A twin stick controller was developed and released for the Saturn specifically to be used with Virtual On. The game was popular especially in Japan[13] and it led to the Virtual On franchise and a 1998 sequel subtitled Oratorio Tangram. In 2007, Cyber Troopers Virtual-On was remade for the PlayStation 2 and released in Japan, while later in 2013 the original version was released on Xbox Live Arcade and PlayStation Network, also in Japan only.
