you need to load or replay before the part where you fight the hunter and you need to be still in the carrier then go to the lab then it shouldn't be locked anymore
Well I loaded to the part, right after you get out of that chair. I tried to get it but it wouldnt let me.
You have to go watch the atomic bomb, and then go back to get the TAC gun, after the aliens invade the ship.
yes I tried that aswell. But the only door that has not been shut and locked is the one leading outside.
What I mean is, you have to go back to a point before the atomic bomb goes off, after that you should have to run around the ship in order to complete various objectives to keep the ship afloat. After you help repair the core, then you should start to head back up to the top of the ship, on your way you have to pick up the TAC cannon. If you get to the point where the Admiral dies, then you have gone to far.
ah ok. Yea I just went through it again. I missed it the first time I went through all that. I keept going to where the admiral dies. Thanks for the help :)
