Labyrinth of the Factory is the third zone of Sonic Labyrinth for the Sega Game Gear. An industrial maze with a modern-looking city in the background, is level includes a profusion of off gimmicks, including glowing floors that slow Sonic almost to a halt - he can actually walk faster than he can roll on such surfaces. Stand on star platforms for a ride, but dismount quickly upon landing or they're liable to disappear from right under your feet. Stand on flashing squares to warp to other portions of the stage.
Time limits are as follows: Zone 3-1 = 1:'30; Zone 3-2 = 2:00; Zone 3-3 = 1:30. The fourth-act boss is Needle Man.
||High voltage! Test your speed against the magnetic conveyor belts, and dodge power bolts coming from the ceiling. Centipede creatures ricochet around tiny, secret platforms - attack or use the square warp gates to get out of the way. Moving star platforms carry you from maze to maze, but beware - some of these platforms explode, leaving you to plummet to a terrible fate!
