Walkthrough

1
Harbor Grand Hotel: Head east from Southwest Harbor to the Harbor Grand Hotel. Clear out Super Mutants on the exterior and roof. Enter the hotel via the pool entrance. Navigate through the hotel rooms to find a keypad that opens a secret room. Inside, find the “To Franny” Holotape, an [Expert] wall Safe, and an [Novice] locked Ammo Box. Interact with the terminal to hear the holotape and obtain the launch code “4467512”. Eject the “Safe Room Security Tape”, which updates your objective to “Obtain the Nuclear Launch Key”.
