I am in the banshee, where they tell me to open the gate. I do, kill everybody but the phantom does not follow. stays airborne outside. when I go inside, the second gate is closed. no enemies left. is there a way to open the second gate. I watched in youtube and it seems it opens up automatically, not for me though. I am stuck. any idea?
I had this happen to me a couple times. I fired a few banshee bombs, maybe 5 or 6, at the Phantom and it eventually moved on. Hopefully that works for you
