Gimmick Mt. Zone, or Gimmick Mountain Zone, is the fifth zone in the 8-bit version of Sonic the Hedgehog 2. Similarities with Scrap Brain Zone from Sonic 1 abound here, as do spikes. Count on everything in this strange, monochromatic level to explode. The boss of this stage is a Drillbot who tries to run you over until Sonic runs him down. A peculiarity of Act 1 is that it ends from right to left, as opposed to most other levels, where you end from left to right.
The Chaos Emerald in this stage is in Act 2. When a burrowing badnik comes out and attacks you, and you see some of those spinning discs above it, jump left into the wall. Try it from a couple of angles if you don't get it at first. Jump left on the tip of the slope leading to the discs and follow the obstacles through to get the gem.
||The inside of this metallic mountain is filled with moving conveyor belts, platforms and whining flywheels. Catch a ride on a wheel, and sling yourself along. Timing is very important! Walking Bombs and Burrowbots roam through this Zone, making your travels more treacherous.
- Drillin — Mole bots that leap from the ground and then simply move back and forth in a small area. Their drill bit noses give them away.
- Buton — Pig bots that hang around at the top of inclines. They just hop in place and roll flashing balls down the hill. Now capable of movement.
- Bomb — Mindless kamikaze bomb bots that walk back and forth along a short plane, either on the ground or ceiling. As soon as Sonic approaches, they stop moving and start flashing: after a few seconds, they explode into a small shower of flashing projectiles. Look out when they attack in groups.
