In addition to its original iteration in Sonic 2, Mystic Cave appears as a racecourse in Sonic Drift 2 for the Sega Game Gear.
This stage is the fifth track of the White Chaos GP (White being the intermediate of the three available tournaments), coming after Hill Top 2 and before Emerald Hill 2. Unlike the majority of races in the Chaos Grand Prix, this isn't a three-lap circular course; the objective is simply to get through the tunnel system ahead of everyone else. And the winning racer gets a Chaos Emerald!
The course is fairly straightforwards, with no track sides to fall off (although slamming against the wall will, predictably, slow you down). As in Quake Cave, the occasional stalagmite jutting up from the floor is the only real obstacle.
