Finish Sonic the Hedgehog 2

Green Hill Zone at speed; Sega's answer to Mario in 1991.

The two halves that lock together into one long game; the peak of Genesis Sonic.

Time travel through four versions of every zone, and two soundtracks depending on where you bought it.

The Genesis Sonic made by fans, officially; the best Sonic since 1994.

Six characters, a killer whale and the Dreamcast's launch.

Classic and modern Sonic through the series' best levels; the birthday game.

Two campaigns, the Chao garden, and City Escape - the last Sonic game Sega made for its own console.

Teams of three switched on the fly, speed, power and flight in one control scheme.
