About CorsixTH

CorsixTH is a community project that aims to re-implement the game engine of Theme Hospital and load the original game's data files. It is not a standalone game: playing it requires either the Theme Hospital demo or the full game, which the project notes is available for example at GOG.com. Once most of the original engine has been re-implemented, the project intends to serve as a base for extensions and improvements to the original game.
