    FreeCS

    FreeCS

    FreeCS is a free-software reimplementation of Counter-Strike 1.5.

    FreeCS is a free-software reimplementation of Counter-Strike 1.5 running on the FTEQW engine. All it is, is a game-logic re-implementation in QuakeC, an architecture independent programming language. FreeCS is not a game-engine as it relies on FTEQW (released under the GPL V2). All this makes it possible to play FreeCS on virtually any platform! No DRM! No third-party accounts! Just download, play, contribute. The game-logic is written by me with help of twhl.info's wiki. It has since been incorporated into the Nuclide project, which re-implements more than just CS 1.5.
