Map of Mausoleum
Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.



  1. The lava lake on the west side of the map has three branches that go to the east, each of which leads to a secret door Undead warriors inside: the further south contains a shadowsphere.
  2. Like the secret # 1, the branch of the medium has some Quartz Flasks.
  3. Like the secret # 1, the northern branch contains ammunition and a Mystic Urn.
  4. In the eastern room with long stairs, the southeast landing has a blue banner that hides a door to a secret chamber, with health, ammo and the Wings of Wrath.
  5. After entering to the exit room, and push the switches, go back to the starting room. Go east to the first intersection and then turn south. Enter the door on the right and go to the northwest corner of the room and push the switch. This will reveal another Iron Lich and an Enchanted Shield.


In case the Firemace has appeared at the level startup, you will find it from one of four different positions. In order of appearance, they are located:
