Bunker Gamma

Bunker Gamma is a base of operations of the Eastern Brotherhood of Steel, located northeast of St. Louis and Mardin. After the Brotherhood defeated the psychic Beastlords, this new bunker was constructed south of Bunker Beta, to firmly establish a secure area of operations.

After Gammorin's super mutants were defeated, the command center was moved to Bunker Delta, constructed in the west. General Simon Barnaky stationed here before he was taken prisoner by Toccamatta. He was replaced by general Dekker.

You can find an easter-egg object (more credits comment on it) in a locked locker, and the quatermaster will gamble with you.
