There is a doorway there you want to go through. Head through the door and down the stairs.Īt the base of the stairs, go to the West and turn to the South. A number more of the Mole Rats will emerge from the ground at the base of the ramp. This will lead you to a door with some downward stairs beyond to the South. Continue to the East through the security door you need to open. On the top level, turn to the East and head into the room labeled "Research".

Try to keep some distance between you and any Companion you have with you.

There are a number of hidden Mole Rats here, so move forward carefully. Go to the Southeast and take the next two ramps up to the higher level. This will last until you take the Vault 81 Cure. If they bite you, you will get Mole Rat Disease that reduces your HP by 10. Be very careful here because Vault 81 Lab Mole Rats start showing up in this area. In the red room, head to the Southeast to get through the corridor and into a wrecked part of the Secret Vault. Take the stairs down then through the red corridor which is to the South. On the lower level, you can head to the East to find a Terminal (Novice) you can hack to access the nearby Protection. Head into the South down the corridor there. From there, go down the nearby stairs to the lower level to the West. In the next room, go through the hole in the wall to the West.Įxit the room you arrive in to the North. Be mindful of the Protectron Watcher that is patrolling nearby this area. Turn to the South at it to continue forward. You will encounter a pair of Machine Gun Turrets on the roof of the corridor. In there, turn to the West and head toward the blocked doorway. Go straight through the room beyond it and into the corridor.

Turn to the East and then go through the first hole in the wall on your left. Inside the Secret Vault 81, you will encounter a lot of bugs ( Radroaches, Bloatflies etc). Bobby will go to a panel of the wall underneath the stairs to reveal the entrance to the Secret Vault 81. In the Reactor room, take the stairs down then immediately head under them. This will lead you into the Reactor room. Go to the North and head down the corridor to the left of the class room. Bobby will head to the South from the Doctor's office.
