Securitron vault

Before the Great War, Mr. House built this bunker under Fortification Hill and filled it with a reserve army of Securitrons and the means to make more, sealed so that only the platinum chip could open it. Benny learned of it through Yes Man, which is part of why he stole the chip. The Legion, Mr. House and Yes Man paths all send you here, and the whole place gives off 1 rad per second.

Past a room with a small copy of House's terminal, protectrons and automated turrets guard the halls, and terminals can shut some of them down. Windows look out over rows of dormant Securitrons. Below is an engine room with doors to three generators and the systems room. For the Legion you destroy the three power regulators, which floods the vault with radiation and brings it down, while House and Yes Man want the platinum chip installed at the console in the systems room.

A side room behind a door that needs 60 Repair holds four sentry bots, which stay calm unless you start destroying generators. Mr. House speaks to you through the terminal near the entrance, with special lines if you show up before ever visiting him at the Lucky 38. Once you leave after finishing your task, the vault locks for good.
