Secrets

 * 1) When you teleport to the yellow key room, open the wall behind where you teleported to find health bonuses and a switch. This switch lowers a teleporter in the building to the east, where you can get a BFG9000. (sector 105)
 * 2) At the top of the building which is just south of the red door, press the lion switch, then drop off to the north and quickly enter the alcove near the red door before it rises to obtain a berserk pack. (sector 153)
 * 3) Head for the building at the north end of the map and get to its right side. Open the recessed wall here for a teleporter, taking you to the top of the wall from before. You can grab armor bonuses on the wall, as well as a soul sphere from the tower where the revenant was. (sector 170)
 * 4) In the southwestern building with all the crates, go to the southwest end of the room and flip the switch, then quickly reach the northwest corner to get boxes of rockets and a rocket launcher. (sector 221)
 * 5) To reach the megasphere in the northeast building, head into the building just south of the fort-like building (using the steps from the slime below that building). This room has several satyr switches on columns, and only the lit one works. Use it, then backtrack to the beginning of the slime tunnels and enter the passage on the right side to get the megasphere. (sector 475)
 * 6) In the northwest building, get on the high ledge and jump down in between the stacks of crates at the northeast side, acquiring the blur artifact in the corner. (sector 498)
 * 7) Take the door on the same high ledge mentioned above, and shoot the barrel in front of the damaged wall on the east side. Open the wall and the next wall to reach the platform with chaingunners, where you can get a box of shotgun shells. (sector 533)
