So, in mission 11 we're supposed to do some extraction thing on the broodlord or something, but it doesnt seem to be explained very well.. for starters, I was already about half way through the mission before it decided to even pop-up the mission 'help' telling me what I needed to do, and even then the popup says 'press m to go to mission objective', but all pressing m does is open the map.
I couldnt find any objective to extract, and the only objective on the map was the exit point, and predictably moving all my guys there just ended the mission in defeat.
I suspect maybe I killed the broodlord on overwatch with assault cannon (I only know this because the achievement unlocked while the assault cannon was firing), there were no corpses left on the ground that looked like I could perform an extraction on.. do you just have to pay really close attention during overwatch fire and try and figure out exactly what square it dies on, and then stand on that square or something? Or now that genestealers pop other genestealers corpses when they walk over it can the corpse be destroyed before you can do the extraction?
This mission could have done with a lot better explanation... so what have I missed?
