Well, this oneâs embarrassing: trapped in a lab.
Found a lab, went down despite having only 1 computer skill at the time. Fight my way through everything, but find myself stumped by the computer-locked doors with hidden goodies beyond. Lacking a digging tool, I happened upon a teleporter and, after a few tries, managed to beam myself into an armory. Loot in hand, I tried to teleport out - and landed back in the armory. I tried again - landed in a locked cell right outside the armory. Again, again, again - each time into the armory, or somewhere just outside the armory but in a locked space. Eventually, my teleporter ran out of charges with me still stuck inside, with no tools strong enough to break through the walls (MGs, no explosives). After exhausting my ammunition and attempting to build a bomb out of the stuff I couldnât shoot, I had to abandon the poor chap to his doom.
