The editor, formally known as The Witcher 3 REDkit, is described as a “comprehensive modding tool” that’s based on the same tools used by CD Projekt to create to Wild Hunt in the first place, and one that “should allow for nearly limitless freedom in modding it”.
CD Projekt’s official mod editor for The Witcher 3: Wild Hunt is now available for playtesting on Steam – albeit initially only to select registrants – ahead of its full release “later this year”.
In addition to the REDkit playtest, CD Projekt has launched a Steam Workshop beta for Wild Hunt, where mods created using the editing tool will be hosted.
Access will be granted in batches, after which the editor will appear in recipients’ Steam libraries – CD Projekt notes users must have The Witcher 3 installed for the editor to work properly.
