Sonic the Hedgehog 2 (World) (Rev A) [Hack by Team Lost Land v2.0] (~Sonic - The Lost Land 2) is a ROM hack by Team Lost Land, modifying the original Sonic the Hedgehog 2 (Rev A) for the Sega Genesis. Version 2.0 indicates a more polished and developed state than earlier versions.  The original Sonic the Hedgehog 2, a 1992 Sega release, is iconic for its gameplay.  This hack, however, focuses on creating 'The Lost Land' storyline. This suggests a significant change to the game's levels, storyline, and potentially, characters or enemies to create a completely new adventure within the Sonic universe.
