Underground Zone

This first zone in Sonic the Hedgehog 2 (Game Gear) certainly breaks the mould; it is not what you'd expect of the first level of any Sonic game. It takes place in a mine, where you ride minecarts to dodge spikes and lava traps. The infamous boss of this level is extremely difficult, and is actually one of the hardest parts of the game. You must use well-timed jumps to avoid both a meat-eating pincer and metal balls that Dr. Robotnik will toss at you.

Badniks

• Motora — Beetle bots that simply roll back and forth in a small area.
• Meleon — Chameleon bots that appear on walls, then transform into missiles and fire themselves on a horizontal path in Sonic's direction.
