Secrets[edit]

  1. At the start, open the wall in the northwest corner for shotgun shells and a switch. (sector 501)
  2. The switch in Secret #1 lowers a lift leading to a soul sphere. (sector 505)
  3. Enter the tunnels in the center of the map and go until you reach a cave with a stimpack (not on Ultra-Violence or higher), a green armor, a chainsaw (only on Hey, Not Too Rough or lower), and a box of shotgun shells. You can enter this tunnel complex from the room with lava by examining the broken wall with the cacodemon corpse behind it, just make sure to look back as soon as the path turns to the north. (sector 98)
  4. When you head outside from the tunnels in the center of the map, climb the rocks up, but do not go all the way to the top. When you are at the left side, you can jump through an opening down onto a rocky ledge. Go along this ledge to a cave containing some ammo and a soul sphere (or a backpack on Ultra-Violence or higher). (sector 314)
  5. In the same area as the previous secret, enter the lava which will cause a rock to the east to lower. Ride this rock as it goes up and drop off onto a ledge southwest of that rock. On that ledge, enter the cave to find a box of rockets. (sector 380)
  6. Outside of the central building, at the south side, head west across the lava towards the green armor. Since this secret is in a cave past lava, you will need some protection, so head north from the satyr switch here and collect the invulnerability. Afterwards, head west around the wooden structure and into the cave, waiting for the rock to lower. When it lowers, go across the lava to reach an energy cell pack, a soul sphere, a megaarmor (not on Ultra-Violence or higher), and a computer area map. (sector 817)

Bugs[edit]

There are 2 untextured walls near the eye in the balance section, resulting in a Hall of Mirrors effect.
