The Maxson bunker entrance is a district of the Maxson bunker.
This is an outdoor area, mostly rocky in appearance. To the north is a small cliff wall, where built into the cliff, is what appears to be a partially concealed hangar door. This door provides entry to the motor pool on the first level of the bunker (the door cannot be opened from the outside). To the right of the hangar door is a small cave mouth, where the main entry to the bunker can be found within the cave.
The entry door is a standard Vault-Tec model with an access computer just to the left. If the Prisoner tampers with the computer, a pair of guards will come to investigate. They will be invited into the vault after a brief questioning. They will then be immediately escorted to the medical center for disease testing, and upon passing the test, they will be given partial access to the base.
