Metroid Prime Hunters Planets

In this game, there are a total of five areas you can explore in the Alimbic Cluster, including Oubliette which holds the Omega Cannon. Now, as you should have figured out by how there are 8 octoliths, there are two per planet. Oh, and there are two bosses in each area (except Oubliette), which means one Cretaphid battle and one Slench battle in each of the areas.

Celestial Archives

Log book information: This space station, in orbit directly above Alinos, is the primary repository of the combined knowledge of Alimbic scholars, scientists and historians.

Information: This space station was a centre for resarch in various fields including science and research, and has been damaged by an unknown object, probably causing all users to flee the place. There are many different rooms related to various functions, and many areas near outer space which have been blown apart by the impact. It is crawling with Guardians, Psycho Bits and various other mechanical threats.

Alinos

Log Book Information: The once beautiful planet of Alinos, home to the Alimbic Elders, has fallen into disrepair since the explosion of the planet's core.

Information: This planet was once home to an alimbic civilisation, and there was clearly a city on this planet. However, something went wrong with the planet's core and it is currently in ruins, with lava flowing both on surface areas and underground caverns. There are many relics of the Alimbic Civilisation here, and as well as the usual mechanical monsters, it is home to various pests such as War Wasps, Geemers and The Fire Spawn.

Vesper Defence Outpost

Log Book Information:

Vesper Defence Outpost is situated on the outer edge of Alimbic territory, serving as a refueling station and munitions dump. Subzero temperature is maintained to prevent overheating of the fusion-powered weapons systems. Structural failure of fuel containers has resulted in a vast radioactive spill into space, leaving toxic and explosive fuel frozen to the sides of the structure.

Information: Once a re-fuelling station and a small defence base floating in the depths of space, the area has been abandoned for an extremely long period, leaving toxic waste to freeze over the area. There are many highly mechanical rooms in this area, and the area is heavily guarded with advanced technology.

Acterra

Log Book Information:

The outmost planet in the Alimbic Cluster, Acterra is an inhospitable wasteland noteworthy of tunnels and caves within it's frozen interior.

Information: A icy planet with many caverns beneath the surface, it is situated at the far end of the galaxy, and the temperatures are often below zero degrees. The power is currently out at the moment for an unknown reason, and there is a minor problem with various monsters lurking around the area, and more.
