By default Exterminatus (EX) features space marines from the Bloodravens chapter. Chapter packs allow you to customize your EX to feature the chapter of your choice instead of the Bloodravens.
Exterminatus has had chapter packs before (you can find them on the downloads page), but they were only built for the EX Beta, scattered files all over your EX install and were missing skins for new classes an some weapons.
This new Ultramarines skin pack is the first of a new set of skin packs, to take advantage of better support in Source 2013 for customization and all the new classes and wargear in EX.
Installation- Locate your "ex" folder, this will usually be C:\program Files\Steam\SteamApps\SourceMods\ , but can vary depending on your Steam installation.
- If you already have an "ex/custom" folder delete any chapter pack folders inside it. You can only install one chapter pack at a time.
- Extract the "custom" folder from the zip file inside your "ex" folder.
These packs work for alpha or beta versions of ex, just replace the "ex" folder name with "ex_alpha" in the instructions above.
If you would like to assist with updating chapter packs for the other space marine chapters, bellow is a link to download the source files and instructions necessary to make your own chapter pack.
If you've decided to make a skin pack for a well known chapter it's probably worth dropping in to the Discord and asking if anyone else is working on the same chapter. When you're done making your skin pack feel free to get in-touch via
