Sonic the Hedgehog 2

Sonic the Hedgehog 2 is a 1992 platform game developed by Sega Technical Institute (STI) for the Sega Genesis. It follows Sonic as he attempts to stop Doctor Robotnik from stealing the Chaos Emeralds to power his space station. Like the first Sonic the Hedgehog (1991), players traverse side-scrolling levels at high speeds while collecting rings, defeating enemies, and fighting bosses. Sonic 2 introduces Sonic's sidekick Miles "Tails" Prower, controllable by a second player. It features faster gameplay and larger levels, a multiplayer mode, and special stages featuring pre-rendered 3D graphics.
