I am doing the marines campaign. I am at the 'unwelcomed guests' level where you have to go down to the cacoon to rescue the female marine, cacooned on the wall. You first walk through a darkened room with computer monitors on the walls. I enter a new room with a huge hole in the floor from acid. From there, you get in an elevator and it takes you down. That is where you find the female marine. When you find her you have to kill her and all that. Well, after i did that, it says I am supposed to go back to the apc. I go back the way I came. I go back up the elevator and kill the alien waiting for me, and then when I get to the door I came from it wont open. I cant use my welder or my hacking tool and there are no other ways to go. No other doors or anything! What the hell do I do!?
Are you sure you are going to the same door from which you came from?
Yeah, I have been wandering around these two levels forever, there are no other doors. The door I came from instead of saying "closed" in the control panel, its now just an open circuit board. But the hacking tool doesnt do anything. Does anyone remember this level?
Ok, I found out what the problem was.. I guess earlier in the level I closed the door behind me. Well I guess you're not supposed to do that because it wont re-open. So I had to restar the whole level and when I went through it again, I just ran out the door. So my bad for closing it but that seems like a glitch on the programer's part.
