Biodefense Chamber A

Biodefense Chamber A is a repeating, circular room located on the Celestial Archives, Alinos, the Vesper Defense Outpost, and Arcterra. It appears in Metroid Prime Hunters. The chamber is always the ultimate room of every first Stronghold Void on all four of worlds, and is the location of all Cretaphids.

Description[]

Biodefense Chamber A is intricately designed in the typical Alimbic style, with numerous patterns of circles and spirals on the walls, and shades of pink and light purple. The walls are divided into segments that join in a circle in the center of the ceiling, with the gaps between each segment glowing purple. A light purple spiral extends from the ceiling around the circumference of the upper walls. Rubble lines the bottom of the walls, and three large structures are positioned around the room, forming a triangle. These sculptures feature a purple crystal that protrudes upward, and is surrounded by a rising spiral that becomes thinner the closer it is to the end.

Destroying the Cretaphid within causes the Octolith and numerous Energy Capsules to appear. Once collected, Samus can leave the Stronghold Void.

Items[]

Octolith: Samus must defeat the Cretaphid to obtain this item.
