Warzone Secret Room underneath BUNKER 11 (drone glitch) (Death Gulag)
We managed to get through the second door in bunker 11 with the drone glitch, at first i thought it was empty as all other bunkers before but then i saw that unrendered area on the left.. it might be an unused room model left there by devs or it might be a secret area hiding something, maybe the NUKE itself, who knows.. we might try doing it again with a bit more time to try to get into the actual room..
EDIT: i went back in there and it's just a gulag model left abandoned by devs, i managed to clip into that, that's where we get sent to when we die..
