Later today on Steam we will be releasing the official tool kit for RAGE — the same tools used to create RAGE and it’s DLC, The Scorchers. From the game’s world building tool, idStudio, to game maps and assets, the kit provides everything you need to get started with modding the first-ever idTech 5 title.
Interested? Before you start downloading the hefty 35+ GB file, the RAGE team has provided some documents to read. As described in the welcome document, these tools provided are complex and aimed towards “technically sophisticated and adventurous” modders.
To download the kit itself, be on the lookout for the RAGE Tool Kit in the Tools section of Steam (the same place you’d download Skyrim’s Creation Kit).
