CD Projekt Red, developers of the Witcher series, has accidentally let their RedKit modding tool website go live, allowing those quick enough to grab the official toolset before it was quickly locked up.
According to a post on the The Witcher's official forums by community manager Marcin Momot, the team were apparently running tests on the website when it was accidentally made available for public. Momot apologised for the confusion caused but ensured that those who had downloaded the tools that they were legitimate.
Just a word of clarification.... We were running some tests on the website and it went public for a brief moment. Those of you who have downloaded the REDkit files - have fun - they are official so don't worry! Also, feel free to use the instruction posted by Kodaemon since it's legit as well.
Momot also advised that the official launch of the beta files will be on Monday, noting that the team will be ensuring that newer links will be made available for better performance.
