Zero Racers (G-Zero) is a cancelled game for the Virtual Boy that was in development alongside F-Zero X that was close to completion. A prototype exists, since the game was previewed by Nintendo Power and has been seen at E3 1996. Gameplay differs in one important point from its predecessor and all F-Zero games released afterwards. In Zero Racers another dimension is being made use of. It is possible to speed through the three physical dimensions of space in the turning tunnels. – [source: Wikipedia]
