Open the door in front of you. Run to the north of the next room, and hit the switch. Go through the tunnel with the armor bonuses, and hit the eastern switch. Run back to the north of the room, and go through the opening. Drop to the ground from the walkway, and run through the southern door. Open the next two doors to the west. Go around the curve, and open the eastern door. Press on the lift in the south, run in the alcove, and hit the switch. Take the lift up, and hit both switches in the newly-revealed closets. Head north, and through the eastern door. Run east until the walls open to the north, east, and south, and then grab the blue key in the east. Flip the switch behind it, enter the southern alcove, and go through the western opening. Take the northern lift, hit the switch, and quickly run to the southern lift. Take it up, hit the switch, and then dash over to the western lift. Ride it up, open the blue door, head north, and open the northern door again.

Jog to the blue door in the west, go up any of the rocky stairways, and head to the switch in the southeast. Hit it, go down the stairway, and enter the eastern tunnel. Take the teleporter, and then jump to the teleporter in the northeast. Go back in the teleporters you arrive in three times, and grab the yellow key in the next compartment. Enter the teleporter, and return to the western, blue door. Go up the stairway again, and open the yellow door. Go up the next staircase, run to the east, and flip the switch in the northwest compartment after it opens. Once the southern wall is lowered, enter the hallway, go up the next stairway, and open either of the doors. Flip the switch to the west to raise "steps" at the edge of the platforms in this area. Go into the teleporter and run southeast until the northeast wall lowers. Open the doors, go down the stairs, and trigger the western switch. Go back out, take the southeast teleporter, and open the southeast doors. Open the eastern door, take the lift down, and flip the eastern switch. Return to the outside, drop back down, and open the eastern, blue door.

Go across the bridge, open the door, and run to the switch in the east. Flip it, and run up the southern stairway. Open the door, head over the bridge, and flip the switch on the other side. Return to where you came from, and head up the stairs to the north. Flip the switch to lower the pillar. Grab the red key sitting on it, and leave through the next two doors to the west. Head through the red door at the north, and go under the skylight to open closets to the east and west. Hit the switch in the northwest compartment, go through the doorway, and go into either one of the northern corners in the next room. Hit the switch.
