As John Carmack promised back in October 2012, id Software's released mod tools for RAGE onto Steam.
RAGE's release is still a bit of a sore point for PC gamers that have grown up with id's games. Creating classics like DOOM and Wolfenstein, id could claim to be "PC first" and mean it. Yet, RAGE's release was a step back for the company and enraged PC gamers. Not only did RAGE not launch with mod tools as id had promised, the game wouldn't even properly run for some depending on PC configuration.
Now, almost a year and a half after RAGE's release, id's finally released the promised mod tools on Steam. The download is a hefty 35 GB, and Carmack warns that it's not for the fainthearted."The toolkit release is not something that we consider consumer friendly," stated Carmack via Twitter, "but it does let you get a look inside the construction process."
For those who aren't daunted by the warning (and this is a warning from John Carmack), the tools are available for download under the obvious name of 'RAGE Tool Kit.'
