Other points of interest[edit]


  1. At the south end (where you land the first time), jump to the west corridor, then go north, open the northern wall at the end, and follow the path to a blur artifact. (sector 26)
  2. In the area with green and brown walls (eastern part of the map), open the part of the east wall that is greener and jump to where the box of ammo and box of shotgun shells are to get a megaarmor. (sector 401)
  3. In the northeast arena area that has spider mastermind in the middle of it, head to the north hall and open a wall to the north to get a megaarmor. (sector 240)
  4. Somewhere around the northwestern part of the map, there is a water corridor between the low-gravity lava area to the north and a water tank to the south. Head to this corridor and when it widens, surface out to get a berserk pack and bio-suit. (sector 183)
  5. This secret is just a thin sector east of Secret #1, but it is inaccessible due to being too thin to reach. (sector 297)
