Sonic the Hedgehog 2 HD (S2HD) is an ambitious fangame begun by a small group of people who wanted to create a remake of Sega and Sonic Team's classic game, Sonic the Hedgehog 2, with high definition (HD) graphics and music whilst at the same time precisely preserving the original gameplay (which continues to set standards to this day). S2HD is intended not to be limited only to presenting a graphically and musically upgraded version of the original game: it is planned to include possible new features after the original is recreated, such as online multiplayer modes, extra levels, and Knuckles as a playable character.
