MAP31: Secret Facility (Hell To Pay)

MAP31: Secret Facility is the sixteenth map of Hell To Pay. Despite the map slot, it is not a secret map: the previous map only has a "secret exit", making progression through MAP31 the only way possible.

Secrets

 * 1) In the room after the starting area, there is a radiation sign on the wall where three Hell knights were. Open this up for goodies. (sector 133)
 * 2) See secret #1. (sector 132)
 * 3) In the room with the nukage, opposite the yellow door, use the elevator and ride it up. The wall of the left side can be opened up for a partial invisibility and a box of bullets. (sector 56)
 * 4) In the same room, there is an indentation on the wall with a radiation sign. Open this for a radiation suit. (sector 84)
 * 5) Whilst the suit is active, open up the wall in the top left of the nukage room and halfway down the first hallway is a wall with a skull on it. Open this to lower an elevator with a stimpack. (sector 86)
 * 6) Continue through secret #5 and you will reach a soulsphere. (sector 129)
