We are running standard Starsiege v1004 in WAR Mode. So you will not need to download any addons to play on the server.
A copy of Starsiege is all you need to get going with the latest patches and master-server fix which is all located in the linked file below. Simply download and extract to C:\
- Starseige (Full Version, Patched & Ready To Play)
If you already have Starsiege you can download these updates/fixes for online play, all files should be extracted into your C:\Dynamix\Starsiege folder while retaining the Zip File directory structure.
A note on the Windows fix, you may need to right click on the Zip file after downloading and then click the "Unblock" button as this file contains a DLL.
