gm_beta_citadel by Jaycie

gm_beta_citadel combines several maps from the Half-Life 2 Beta into a single, large map.


- A large map that combines many different Citadel areas
- 3D skybox.
- Consul's office
- Several areas from the Half-Life 2 concept art
- Cell block/prison area


- the soundscapes don't really work if you noclip around, so watch out for that.

This download looks like an addon. You need to extract the downloaded zip and put the addon folder in your Garry's Mod addons folder. You should end up with a directory structure similar to below:

  • steamapps
    • common
      • garrysmod
        • garrysmod
          • addons
            • gm_beta_citadel <-- Addon folder!
              • e.g.
              • lua
              • maps
              • materials
              • models
              • etc

Don't know where the Garry's Mod folder is or how to extract zip files? See more useful installation tips.
