The gamemode "Aftermath" is developed by Silverlan, he is the only one who owns and works on this gamemode. This gamemode is based on the game "Fallout3", but using different ideas from The Hl2 Renaissance pack (Created by the same author) and Hl2 and others games. "Aftermath" is a Rpg-like gamemode in which you (will be able to) interact with other players, kill creatures to gain experience, skills, and complete quests. This Gamemode is currently in beta, and is open to the public for now.

Instruction how to download the gamemode:

In Order to download the gamemode (takes about 2.6 Gigabyte memory) you need to get the Programm Tortoise SVN

After installing it go to your Garrysmod steam Folder usually located at
C:\ProgramFiles\Steam\YourUsername\Steamapps\Garrysmod folder and in that garrysmod folder, there should be another folder called also "Garrysmod", right mouse click on it and look for the Tortoise SVN button and then go to SVN checkout, now a Window should appear
Then you just copy and paste this Link:

into the Url bar and press ok, the download should start now. (May take some while since it is 2.6 Gb)
Updating works the same, since we are updating this Gamemode also with that tool.

You need Also the map gm_atomic which you can download HERE

It is recommended that you have 2 Gigabyte RAM or more.

Error: When Connecting to the Server it says "You do not have the correct Content to get on this Server"
Fix: Try to locate in your steam/steamapps/Yourusername/Garrysmod directory a Folder called Aftermath-RPG (or something similar), then copy the Content of this Folder into the steam/steamapps/yourusername/garrysmod/garrysmod folder and overwrite if it asks (and it should ask usually)
(Thanks to EvilAngel)

Thank you for your attention and we will meet us on the server.


couldn't you just up load it as a .rar on a file share we site? It would make installation so much simpler.
