This file adds new scenario Galaxies for the mod, just uncompress it in the folder where you installed the Polaris Sector Alliance overwritting all files. These files will work with the version 1.06e and probably with versions before 1.06d (non tested). Only if you have the Lumens DLC, you can play the First Order Scenario. But remember, I have not added the Resistance yet.
If you have any question, go to Firefoxccmods.com , I sorry but I will not answer you here.
