MAP31: Monster Mansion (Eternal Doom)

MAP31: Monster Mansion is the thirty-first level of Eternal Doom. It was designed by Jim Flynn and uses the music track "UAC 5-0". It is the sixteenth level in overall megawad progression, because MAP15 can be exited only via the secret exit. Likewise, you must exit this level to Map32.

Like Map15, this level was part of the Eternal Doom III upgrade, but twelve levels (Map32 and Map16-Map26) from the Eternal II section still remain.

Secrets

 * 1) The fountain north of the start with the soul sphere counts as a secret. (sector 4)
 * 2) In the guard control room, head between the second and third monitors and look for a switch behind the third monitor. Then, use the switch in front of the first monitor if you have not done so already and enter the monitor by pressing use on it. You will appear in a prison cell. Grab the soul sphere in front of you, then open the door ahead. Take this passage through the cell gates until you reach the computer area map. (sector 364)
 * 3) In the northern portion of the mansion, use the outer edge of the steps to climb up and go east, as if you were going towards the hidden wall on the east side. When you see the warehouse portion of this area, jump to the railing where it is, then jump to the railings to the west. Open the wall to the west to find two chaingunners guarding a megasphere. (sector 584)
