Dark and desolate, this primary section of the BOTTLE SHIP is too quiet for comfort. It acts as a gateway to the more chaotic sections of the ship.
Sector 1 of the BOTTLE SHIP is known as the Biosphere. The lush, tropical environments are home to all kinds of jungle creatures, like Rios, Keyhunters, and mobile flytraps. Almost all seem aggressive and hostile.
Sector 2 of the BOTTLE SHIP is called the Cryosphere, a chilling place covered in snow drifts. Its sub-zero temperatures sustained many recognizable Zebesian life forms.
The Pyrosphere, a simulated volcanic area encompassing Sector 3, is predictably awash in magma flows, lava pools, and a host of beasts adapted to extreme heat. A pyroclasmic volcanic eruption necessitates the Varia feature of Samus' suit.
