Mod:Vault 120

Vault 120 is a mod that restores the cut underwater vault into Fallout 4.

About
''While the cells were removed entirely from the game, when Fallout 76 was released, Bethesda left the cells made for Vault 120 in the 76 game files, leading to them being datamined. Ladle was able to backport these cells back into Fallout 4, allowing everyone to enjoy what this cut vault had in store!The vault was host to a number of ambitious features and ideas, such as: A sub battle resulting in a crashed Yangtze, Captain Zao, escape pods, a giant squid overseer, walking around underwater in power armor, dolphin/aquatic life experiments, robot ambush attacks and some guy named James!''
