Psyvariar (?????? ,Saivaria) is a vertically scrolling shooter arcade game developed by Success Corporation on Taito's G-NET hardware. Two versions were released — the original version Psyvariar Medium Unit in March 2000, and an updated and remixed version Psyvariar Revision in September 2000. Both were later ported for home release on the PlayStation 2 console.
Psyvariar Complete Edition was released for the Sony PlayStation 2 in Japan on 28 March 2002 by Success. It contains both Psyvariar Medium Unit and Psyvariar Revision on a single disc. The main additions are a replay mode and the option to use a separate button to spin the ship as the waggling motion is harder to perform on a joypad.
Two special editions were also available in Japan. The Special Sound Box included an audio CD of the game's soundtrack, and the Special Capture Box included a gameplay DVD of both games being fully completed by expert players. Both games were also released separately as part of Success' budget range in 2003.
Psyvariar Complete Edition was released in Europe on 26 September 2003 by Empire Interactive at a budget price under their "Xplosiv" label. This version retains all the features of the Japanese release and includes a 60Hz mode.
