Ive never seen this before. One large square. Spooky. The one-wide corridor goes all the way around it (but doesnt quite fit on screen)

what all was in that vault, as far as the items go

jack sh*t. Was a pretty depressing vault, loot wise. Oddly spooky tho, to be in a space that wide open at the bottom. Alls it would take is one Q to spawn in and it would be game over.

I've run into those a few times, as if it's not bad enough with the long corridor around it... it has to have a giant room inside too. Rarely worth the risk, though a bit safer with a geno'ing mage  ::)
