Psyvariar is a vertical scrolling shooter released in arcades in 2000 by Success Corp. Revision is a remake of the original version and was released some time after. It featured the same stages, but re-ordered and some minor edits. In Revision, to be able to reach the harder stages, you are obligated to reach higher levels than before. The buzzing mechanic is almost identical. In this game, a bullet can be buzzed as many times as possible. This allows the player to reach higher scores and levels. This game also contains a 'Replay Mode', which let's you watch replays of stages and choose a stage to play. A replay is unlocked only if the player completes a stage without using up any continues.
