After getting the key card from the Wang Fou Incident you most likely went to Asylum Aftermath to collect your Mini Gun. After that continue thru the level and when you get to a large room with windows and the door ahead… STOP! One patient will be walking around and on your right will be steps leading down to a door with red lights over it. Enter that room with the key card. Walk forward until you find the Gold Desert Eagle Guns right under your nose!
Unlockable: Mini Gun:
The mini gun is held by a patient who is behind the locked doors of a basement room in Mission 1: Asylum Aftermath. The keycard that unlocks the doors can be found during Mission 9: The Wang Fou Incident. It is called Orthmeyer?s Keycard and is on Lee Hong?s desk in his office on the second floor of his mansion. After finding the card, finish the mission and save your progress. Quit to the main menu and replay the first mission.

Pass through the west door and dispose of the patient in order to collect the mini gun.
