 After all, Grievers are defeated, continue ahead. Scan membrane blockages to direct VUE-995 to destroy these. Keep going onwards until you reach an area with a Mining Cannon hanging above; use Morph Ball to travel along the walls and power the two mechanisms with Boost Ball. This will drop the cannon and attract the attention of more Grievers. |
| 5 |
 With the Grievers gone, direct VUE-995 to break the frame with a scan. Blast the frame with a charge shot, then obtain the Super Missile. Defeat another wave of Grievers. ┗ How to Use Super Missile |
| 6 |
 While at Easing Tunnel, destroy the Koornicite Ore with Super Missile and take the Missile Expansion in it.

 In the next area, you will need to get across the room. Aim your Psychic Grapple at the hook in a hidden path located above the door entrance on your right. Double jump to reach the distant platforms until you get to the other side. Direct VUE-995 to burn down the path blocked by a membrane to get to the next area. |
| 8 |
 Use the Psychic Grapple to destroy the lock going to the next area. Keep directing VUE-995 to break down the membranes by scanning them as you go further. Watch out for the Goura Ghaspores in the area that will aim their sporangium towards you. These sporangia are impenetrable, so you will need to deflect them by shooting them. Make sure this is directed back to the Gouora Ghaspores to defeat them. |
| 9 |
 Continue to the next area. VUE-995 will be incapacitated after attempting to break down a membrane. Fend off the Grievers and the large mutated variant. VUE-995 will free himself afterwards and destroy more membranes. Run through the tunnels to evade the Grievers before facing them. |
