CD Projekt RED has released REDkit, an official set of tools that allows amateur modders to make The Witcher 2 even witchier than ever before.
REDkit, originally launched as a private beta back in August, is a robust toolkit that lets users create new characters and quests within The Witcher 2. If you want to further tweak your mod's fantasy setting, REDkit also allows modders to edit terrain and plant virtual forests using the SpeedTree system. User-created content can be shared with fellow Witcher series enthusiasts at CD Projkt RED's website.
Would-be modders might want to check out REDkit's wiki before delving too deeply into the REDkit's world of character creation and tree-planting.
