During their Fall Special Event, CD Projekt RED presented a beta version of their development kit, called REDkit, a unique development tool that allows any player to create a "living world" with the use of advanced landscape design tools, 24-hour day-and-night-cycle simulations and thousands of ready-made assets used in The Witcher 2. It also makes it possible to modify the original game, a great opportunity for the modding community. During the conference, over 100 modding teams selected from a pool of over 600 squads were given access to it. These modders will assist in the development and perfection of the tools and the game engine itself.
Currently in the Closed Beta phase, the REDkit toolset will be available in the first half of 2013 for free and to everyone who owns a copy of The Witcher 2.
