This is for all of you new people who are struggling to actually find how to install and run Colts Halo Factions for Call to War.

1. You subscribe to the mod

2. Once it's installed you open the game and go to the home tab. In the top left, right underneath the version number, there will be a sub-tab called 'workshop.' Click it.

3. You click on Colts Halo Factions and activate it.

4. NOW IS THE IMPORTANT PART!!
...ready?
You click apply at the bottom of that tab.

I spent over an hour trying to figure this out and I'm sure I was not the only one to be confused with CTA mods (maybe). Enjoy! :D
