Welcome to the 'unofficial' CorsixTH Steam group (we hope an official one comes soon, feel free to join to show your love of Theme Hospital and Corsix)

The open-source project CorsixTH aims to reimplement the game engine of Theme Hospital, with the capability of loading assets including graphics and levels from the original game. This means that you will need a purchased copy[www.gog.com] of Theme Hospital, or a copy of the demo[th.corsix.org], in order to use CorsixTH. After most of the original engine has been reimplemented in open source code, the project will serve as a base from which extensions and improvements to the original game can be made.
