Here are 183 custom maps for Red Faction. Yes, as in OG RF. JeTbike Extreme has a map or two in here, as there are many maps from the old community as well.
Turns out I still had them on an old hard drive. Mirrored and ready for your downloading pleasure. An image map of the contents is attached to this post.
183 RF Maps for your pleasure. Right around 200 MB for the .rar archive.
According to the file info, these files are circa 2001 – 2003. Also tipped off by the terrible.jpg compression from when I made the image of the contents.
