Fallout 4: Vault 75 (Malden Middle School)
There you will find a group of shooters and turrets. This is also where the quest will start. Run to the elevator ahead. Ride down to lower floor. There you will have to face another group of opponents. Keep going through the main corridor. After a while you will reach a large dining room. Enemies are waiting for you on the balconies as well, so be careful. Walk through the door and go to the end of the corridor....
