So I just got into Vault Hotel and I've run across an unused section in the very back of the vault (south side). I had to tcl through an inaccessible door to get over there but there seems to be an incomplete stretch of hallway. I just thought it was weird to see. I wonder if there was plans to make the vault bigger. In convo with the proprietor she mentioned something about the rest of the vault being closed off. Could be a hint into the development cycle of the game! haha
