Other points of interest[edit]

  1. The non-secret computer area map is on a damaging pedestal.
  2. The trap in the red key room has a chex armor, simply go through the slimed wall the flemoids came from.

Secrets[edit]

  1. The bookshelves at the very first chemistry room need to be pressed to open up a secret with a computer area map. (sector 125)
  2. The vents in the first gray non-secret area are passable through, simply go through the vent opening and crawl into a transport area, jump into the teleporter pad to get launched back into the very first chemistry room. (sector 231)
  3. The vents on the central pillar in the key-locked door hub area have the same effect as the second secret, go through the vent opening to get a chex armor. (sector 149)
  4. The room after the full potion room needs to get its right glass cupboard pressed to open up and reveal a zorch propulsor and a zorchpak. (sector 203)

Bugs[edit]

  1. Some walls are shootable through.
  2. There's a common flemoid outside the map.
  3. There's a flemoidus cycloptis stuck in the exit room.
  4. There are two computer area maps in the map, thus making it impossible to get 100% items, since the player can only pick up one map per level. However, some source ports allow picking up both computer area maps.
