3 0 2just gain friendship from a few outposts, get rid of the prime on the planet and make sure you have at least 1 armoury. This seems to be safe approach to 100% allianceShowing both comments. Leave a comment. I am not sure what I am doing wrong, but I have every planet at 100% alliance, but I still haven't earned this achievement. I have at least one of all the building types, and there are no enemy structures or vacant build spots. I can't figure it out.Posted by Trout Juice on 09 May 20 at 17:23 If you have 100% then it should unlock. Its only a single planet required.Worth trying a new game and going straight for that single planet dominance to see if it unlocks? Assuming that save game you have already thinks its got cheevo unlocked so it doesn't trigger again... just guessing...Posted by Jdobem on 10 May 20 at 14:27 Leave a comment
