This is not a shrunk-down copy of the Genesis game. The 8-bit Sonic the Hedgehog 2, developed by Aspect and released in 1992 alongside the Master System version, has its own story and its own zones. Tails has been kidnapped by Dr. Robotnik, and Sonic has to cross areas like Underground, Sky High, Aqua Lake, Green Hills, Gimmick Mountain and Scrambled Egg to save him. The levels introduce rides that never appeared in the 16-bit games, including mine carts underground and hang gliders in Sky High.
The Game Gear version has a reputation for difficulty, starting with the first boss in Underground Zone, which has stopped plenty of players cold. The handheld's small screen makes high speeds risky, and the game has no spin dash. Chaos Emeralds are hidden through the zones, and only collecting all of them reveals the full ending and a final zone.
Tips for Sonic the Hedgehog 2
Expect the Underground Zone boss to take several attempts; watch its full pattern before committing to an attack.
Search acts thoroughly for Chaos Emeralds, since missing even one locks you out of the good ending.
Slow down in unfamiliar areas, because the small screen gives very little warning of spikes and pits ahead.
