Go back into the elevater room, and kill the people if you already didn't. Climb the ladder and then jump or push A. If you jumped, keep going forward. This is the fast way because ounce you get in the middle you see a symbol, push A and push down. Fisher should connected a wire to his harness. And then he'll drop down when you push down. Then you end up on a platform. Wait for the elevater to come up. Jump on it. Stay there until it goes down. Keep doing this until you see a window on the wall of the window. Push down the anolog stick and fisher will go against the wall. Make sure you're not kneeling. Go up to the window until Fisher looks inside. Then push X an fisher will stick in his pistol. Shoot the man in the window (make sure iits a head shot or he'll go in alert and attack you. But theres more. Jump in the window and pull out a machine gun and shoot all the gaurds you see own the hallway. Go into the room with an open door. That should have 2 people in the west room and to in the east room. Thats Dr. Aswats room! Good luck!
