Metroid Prime Hunters/Return to Arcterra

Arcterra Gateway

Once you exit your ship, drop down to the ground floor and head through the door to Sic Transit.

Sic Transit

Head out of the hallway into the main area of Sic Transit. You will see a door sealed with an Orange Force Field. Switch to Magmaul, blast it open and head into Fault Line.

Fault Line

Scans:
 * Lore: Alimbic War 09
 * Lore: Seal Sphere 01
 * Object: Shock Barrier

When you step through the door, you will find yourself in a small cave. The cave is crawling with Quadtroids, to make it safely through the cave, kill the Quadtroids long distance with your Missile Launcher.

Fault Line

Scans:
 * Bioform: Artic Spawn
 * Equipment: Imperialist
 * Lore: Alimbic Prophecy 08

When you come out into the next area, an Artic Spawn will attack you. Use similar tactics against the Arctic Spawn as you did against the Fire Spawn. Take cover behind the slab of rock leaning against the wall, and when the Artic Spawn dives down into the snow charge a Magmaul shot and wait for it to come back up. Fire the charge shot into the beasts mouth right as it opens to score an amount of damage. Once you have slain the Artic Spawn, you will be rewarded with the Imperialist. Once with the Imperialist, you can take a practice shot on the Imperialist switch, which will activate a platform to the upper levels. Ignore the platform for now and blast open the door with the Red Force Field. Head into the next room and enter the Frost Labyrinth.

Frost Layrinth

When you come out into the Frost Labyrinth, make your way through the maze to the upper area. Head through the tunnel and into the small room. Blast the Red Force Field and step out into Santorus.
