I have also seen that if you spawn in the mission. If you look on the other side of the ......lets call it a feeding beam.....there are a few cabal on the other landing platform that have nothing to do wth the mission i think. But you can still shoot them. 1 with a shield...a few with shields and a few psions. Why would they spawn there for no reason?
I managed to parkour my way over there, there are invisible walls and the troops disapear so i dont think your meant to go there.
Didnt mean you should go there. Just wondering why they spawn in an area you never go to.
