 * 2) In the room where you are to press switches to raise a bridge to the north, you will eventually open up the room to the south. This room counts as two secrets. (sector 49)
 * 3) See Secret #2. (sector 61)
 * 4) Flip the switch where the blue key is to lower the key, and then walk over the blue key to the wall to the north. Doing so opens two closets, each containing monsters and each counting as separate secrets. (sector 140)
