Did you complete it via the campaign? Skirmish mode won't do it.

Hi, I tried and I got the achievement already. Thank you very much! :D

Hey I know this is an old thread, but I too can't get the achievement to unlock. I did it through the campaign several different times, and different difficulty settings as well. Anything special I should be looking for or do?

Which mission are you playing?

I am playing through on Story mode, and according to the achievement list, this one should be unlocked by beating all the hives on the Abyss map. That is the map I am doing. Am I missing something or not doing it right?

Is it a raid map? The achievement is only tied to the raid mission type.

It says the maps are random when I choose Abyss, but all I ever get are the "Capture All the Enemy Points" missions

The mission type depends on which hex you click on the campaign map. If you want to do raid missions, look for the hex that says Raid.

Random mission just means that the map is procedural vs hand-made.

OK I feel like an idiot. I didn't realize that the first two "side" branches were the same name, but the first set of levels were all raids. I kept playing the second branch where none of them were raids. Thanks for making me look at it again and realizing my error. Got the last achievement. Thanks.
