rp_pripyat_fixed
Does not require CS:S or Episode 1/2.

Some people are reporting that this crashes their Garry's Mod, I have no idea why this is happening.
All I can suggest is that you unsubsribe from it and delete it from your Garry's Mod folder.

You can also try downloading the map file directly from http://www.underdone.org/downloads/rp_pripyat_fixed.zip
Extract that file into your garrysmod/maps folder.

The map rp_pripyat with all models/textures packed into it so that you don't need to go download all the Stalker addons required to see them.

Note: A couple of sound effects are missing from the map and your console will warn you about them, join the above server to get the files.

If you are using this on a server you will need "+r_hunkalloclightmaps 0" in the command line.

You can find the Nav Mesh here:
