| Go to level nine, The Wang Fou, incident and go in the restaurant. Hop on the elevator on the first floor and take it down to the basement.

Head up to the mansion's first floor and flip on your night vision goggles. Wonder around in the dark until you find stairs that go up to the second floor. Once upstairs find the office and on the desk you will find Orthmeyer's Keycard. Go back down to the basement and head back upstairs to the first floor of the restaurant. Finish the level like normal and save. Now exit to the main menu and start Mission 1 - Asylum Aftermath. Now find the first key card door. There will be a patient pacing back and forth with the mini gun, kill him and take it. You'll be walking much much slower now because it weighs so much. Find the second keycard door in the basement to get the duel gold desert eagles and finish the level with those two guns in your inventory. Now sit back and enjoy the fruits of your labor. | |
