    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.

    Dungeon Craft

    Updated emulator of Forgotten Realms: Unlimited Adventures

    Up to date code, including latest engine and editor releases: https://github.com/grannypron/uaf Dungeon Craft Community Forums: https://forums.goldbox.games/index.php#c8 Dungeon Craft is an adventure creator that emulates the Advanced Dungeons & Dragons Gold Box RPG's released by SSI. Initially designed to be a "more unlimited" version of the Forgotten Realms: Unlimited Adventures (FRUA) game editor and engine, it has far surpassed the capabilities of the old FRUA system. The editor is used to configure art, items, monsters, spells, special abilities, classes and races.. Each adventure is self-contained and doesn't require the editor to be played. The editor is extremely versatile and the databases are completely designer created allowing easy additions and modifications to spells, monsters, items, classes, races and special abilities, and are exportable to be easily shared with others or used in other designs.
