The Keep is a food and munitions supply base for the Usean Rebel Forces. It located in the hilly region of Amber Mountains.[1]


Before being seized by the rebels and dubbed The Keep, the building was an old, abandoned castle.[1]

Usean coup d'état

On April 14, 1998, the Usean Allied Forces launched an operation to wipe out enemy presence within the castle's walls. The Scarface Squadron was dispatched to Amber Mountains, where The Keep was located, to destroy all rebel presence in the area. With the supply base captured, the Allied Forces were able to regain control of Amber Mountains.[1]
