Sierra Army Depot
From FOnline: 2238 Wiki
The Sierra Army Depot (S.A.D.) was built in 1942 as a storehouse but later became renovated into a research facility, in the year 2050. After the war, only the robots survived, there. Located in the desert above New Reno, it is home to an important device for crafters : the Ammo Facility Terminal. It features four underground levels, haunted by powerful security robots.
Be wary of this area as it is sometimes prone to player-killing and there is only one entrance to it at the moment.
