Grind Stormer, also known as V・V (ヴィ・ファイヴ 'Vee Five'?), is a vertically forced scrolling shoot 'em up developed for the arcade by Toaplan, and ported to the Sega Genesis in 1994 by Tengen. The game takes place in the year 2210 where 'the ultimate arcade machine' Grind Stormer/V・V has finally been released. A VR shooting game, Grind Stormer/V・V becomes so addicting that the government assigns a young man to investigate the arcade phenomenon in order to question its true purpose and to perform the impossible: to beat the game.
