Sonic the Hedgehog 2 (8-bit)
Under Ground Zone

Next zone >>

Hop on a runaway railcart for the ride of your life through showers of spikes and over daredevil jumps. Buzz-saw your way through to secret tunnels and hidden Monitors. Sometimes it's hard to get enough momentum for a good ground attack, but get a running start and keep trying!

— United States instruction booklet, Sonic the Hedgehog 2 (Sega Game Gear)[1]

Under Ground Zone (アンダーグラウンド[2] Andāguraundo?, lit. "Underground") is the first Zone in the Master System and Game Gear game Sonic the Hedgehog 2. As with all other Zones in this game, Under Ground Zone consists of two standard Acts followed by a shorter, third Act which contains the Zone's boss.


The Under Ground Zone is a hot, rocky Zone filled with rail carts and magma pits. Craggy mountains also rise in the background.



Under Ground Zone is filled with Minecarts which Sonic can ride, and damage-inducing magma pits which the Minecarts invariably dump the player into. There are also a number of spin-dash-able walls leading to hidden goodies such as extra lives.

The boss, 'Antlion Mecha'

During Act 3, and in a rather unlikely turn of events, Sonic is saved from a fiery death by Dr. Robotnik in his Egg Mobile, who decides he would rather watch his spiked adversary die at the mandibles of his latest creation, known as the Antlion Mecha.

Sonic has to dodge a variety of fatal bouncing rubber balls, while simultaneously avoiding the robotic claws that lie in wait at the bottom of the pit.

This boss is generally considered to be a lot more difficult in the Game Gear version of the game, as the smaller screen size for that system drastically reduces the time a player has to get out of the way of the descending kill-balls.
