27 1 2Actions Report Solution This is a story-related achievement and is unmissable. Just beat all the missions in sequence 5 (3 missions, no optional objectives required). Unlocked after you finish the mission "Unmanned".Showing both comments. Leave a comment. Is anyone else having issues with this achievement (and a few others) not unlocking? I've 100% all the main missions and have 3 of these sequence ones that just won't unlock. Have hard reset the console, reinstalled the game - all that and nothing. Don't really want to play again as one of the achievements is the one for getting all the stelae which is playing 95% of the game..Posted by DukeØMercury on 28 Oct 22 at 10:36 I am, yep. Did you end up unlocking it?Posted by HaIfaxa on 05 Nov 22 at 04:36 Leave a comment
