Sonic 3D Blast
This mixed-up mechazone is chock full of pipes, tubes and wiring. Not to mention electrified floors, shocking beam weapons, and industrial fans that will blow Sonic away!
— Description, Sonic 3D Blast manual
Gene Gadget Zone is a fraction of Dr. Robotnik's base on Flicky Island. This zone has three acts. In Acts 1 and 2, Sonic must free captured Flickies from inside Badniks, depositing five of the birds into a Goal Ring to progress between sections of the level (usually three per Act).
Getting around the Zone involves large transport tubes and industrial fans that turn on conveniently as soon as Sonic steps on them. Electrified floors are also a problem here, but can be avoided with the Electric Barrier, which is less abundant than the Flame Barrier in Volcano Valley Zone.
Dr. Robotnik floats his Egg Mobile right above a conveyor belt and lets pattern-placed mines do his dirty work. Sonic must avoid the mines, as he cannot wait at the end of the belt for safety, since there are spikes back there. When Robotnik decides to swoop down and fire a brace of missiles at Sonic, Sonic can jump on him.
