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
Seemingly the power plant of Dr. Robotnik's base, this Zone features many mechanical gadgets including tubes, electrical conduits, cables, fuses, and round flasks containing an unknown yellow liquid. The machines are seemingly floating in a black abyss, similiar to The Final Fight. In the Sega Saturn version, the ground has a metallic, factory floor pattern to it.
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.
- Tails and Knuckles do not appear at this point of the game anymore. The player cannot try for the Chaos Emeralds, and no bonuses can be collected from Knuckles and Tails, and those bonuses are not even present at the end of Act tally.
