Walkthrough
  1. 1
    From the Elevator to Main Sector, head left into the Crater Interior.
  2. 2
    Climb the slope to the launch module and return to Crater Control.
  3. 3
    Head outside to Crater Approach. Cross the first two breaks in the bridge, then use a Shinespark to cross the largest gap.
  4. 4
    In Floor Observation Room, defeat the Asborean, use the terminal to unlock the elevator door, and retrace your steps, Shinesparking over the broken bridge.
  5. 5
    Exit the Elevator to Main Sector to the right, entering Furnace Entry.
  6. 6
    Witness Anthony's fight with the Rhedogian. Target the red module hanging from the ceiling and use the Grapple Beam (A while targeting) to swing to Anthony. Jump off (A or 2) to join the fight. Defeat the Rhedogian.
  7. 7
    Proceed through the next passage into Molten Passage.
  8. 8
    Defeat the Magdollite, then swing across the Grapple Points.

    Before the door at the end, jump down a small blue passage to find an ENERGY PART.
  10. 10
    Return to the upper floor and proceed into BLAST FURNACE OBSERVATION.
  11. 11
    Drop down the hole to your left, use the Grapple Point to reach a ball tunnel. Roll through and Bomb away obstructions.
  12. 12
    Roll to the other end and use the terminal to open the furnace hatch. Enter the furnace and use the Grapple Point.
  13. 13
    Boss Fight: VORASH
    • Avoid the Vorash's lava attacks.
  14. 14
    Blast its obvious weak spot when possible.
  15. 15
    When it roars, target the Grapple Point in its mouth and use the Grapple Beam to pull it from the lava, exposing its underbelly for Missile attacks.
  16. 16
    After half health, the Grapple Point is destroyed. The Vorash will crawl onto the rocks; attack it with beam shots to finish it off.
  17. 17
    Exit the furnace, climb the shaft, and head out the door to find a Nav Room.
  18. 18
    Adam instructs you to head west, but you must finish the current area first.
Tips
  • Use Shinespark to cross large gaps in Crater Approach.
  • The Vorash fight requires precise use of the Grapple Beam to expose its weak points.
