The San Francisco Brotherhood outpost is located inside the Chinatown of San Francisco.
Access to the bunker is granted by Matthew upon successful retrieval of the vertibird plans from Navarro for the Brotherhood of Steel. If the Chosen One has obtained the plans, he will find an impressive amount of loot within the bunker (see below) and may also wish to make use of the ACE computer to boost their SPECIAL stats.
Enhancing the SPECIAL stats requires the memory modules in order to use: blue for Charisma, green for Perception, yellow for Intelligence and red for Strength.
The San Francisco Brotherhood outpost appears only in Fallout 2.
