Metroid Prime Hunters/Oubliette

Once you exit your ship head onto the elevator. At the top take the portal. Through the portal you will come to a chamber with the lores Sealing Gorea 1-5. Scan these and take the door to the left of the portal. The door at the end of the massive hallway leads to the battle against Gorea, but a quick detour will prove worth your time. As you enter the room turn to the right and go through the Morph Ball tuunel to it's end. As you exit the tunnel be prepared, because it exits to a small ledge. Switch out of alt-form and jump to the platform to your right and go through the portal to get the seventh and final energy tank. Return through the portal and jump down and go through the giant doors to the final battle. When you enter, walk to the center of the room.

=Gorea= The battle with Gorea shouldn't take long if you are experienced with the game.
