Secrets

 * 1) Just before the yellow door is a secret door (marked with a different texture) to the south leading to a room with some health and armor. (sector 8)
 * 2) After going through the various locked doors in the northeast, there is a switch that raises a staircase. The wall opposite the switch has a secret door further north leading to a room with nine health bonuses, nine armor bonuses, two medikits, and some ammo. It is also possible to reach this area by teleporting into the maze near the end, then heading south then east. (sector 66)
 * 3) After the aforementioned staircase is a passage with some lost souls. There is a secret door to the north here, leading to another lost soul and a chainsaw. (sector 54)
