Sector 2 / Cryosphere(セクター2・クライオスフィアSekutā 2 · Kuraiosufia), is the arctic environment on the BOTTLE SHIP. The Cryosphere is a frigid environment created to sustain life for the various creatures of the BOTTLE SHIP that are adapted to live at cold temperatures. Many species such as Volfons, Gigafraugs, Himellas and even the plant-like Groganch are seen here. Rooms in the sector include the Water Tank, the Sector Generator Room, the Experiment Floor, the Materials Storehouse, the Materials Transfer Lift, and Nightmare's Room. Adam authorizes Samus to use the Speed Booster and Shinespark simultaneously and the Wave Beam here.
