Metroid Prime/Morph Ball Bomb

Gathering Hall

Proceed out of the Save Station to the Gathering Hall. Directly to your left is a ledge. Jump up on it, turn to your right and begin working your way up the room along the ledges around the perimeter of the room. Various hazards will present themselves. Proceed to the Energy Core (Path: East Atrium, Energy Core Access, Energy Core)

Energy Core

Scan: Stone Toad

Upon entering the Energy Core there is a toxic pool ahead, and a tunnel to both left and right. Take the left tunnel, get the Stone Toad scan and roll through the Morph Ball tube.

Burn Dome

Proceed through the Morphball tunnel and get ready for another fight.

Miniboss: Incinerator Drone

Scan: Incinerator Drone, Barbed War Wasp

This is actually a two-party miniboss: the first party is the Incinerator Drone. It shoots fire in opposite direction from its location in the center of the room. Occasionally it pops up a red electric 'eye' which is its weak point. The second party is a massive War Wasp Hive (there's no way you can get rid of it with mere missiles).

Avoid the drone's fire by focusing on the center and circling in sync with it. When the eye pops up, refocus and fire; there are two eyes that face opposite directions and only the eye itself is vulnerable. Once wounded, the drone sends a blast of fire directly at the hive, damaging the hive, and sending out angry War Wasps. Now you have wasps to fight and a blowtorch to avoid. Wash, rinse, repeat. Eventually you'll finish off the drone (4 rounds of eye pop ups), and coincidentally, the hive will be destroyed at the same time. All that's left is to collect your Morph Ball Bomb upgrade.

Don't forget to use your new upgrade to blow a hole in the Morph Ball tube, and roll through for an easy Missile Tank upgrade. Exit back to the Energy Core.
