In this strange music rhythm game, you play Gitaroo-Man as you go against various music themed villains. The game puts a new twist on music games as you not only have to time button presses but you have to move the analog stick around in a radar circle to follow a line that passes through the center point. You can play up to 4 players using the multitap and choose from a variety of characters, songs, and locales. Along with local Ad-Hoc multiplayer and additional difficulty options, the game adds a new Duet mode, in which two players control Gitaroo Man and Kirah in two exclusive new stages, "Metal Header" and "Toda PasiĆ³n". These levels may also be played alone if the handheld's Ad-Hoc is activated.
