Crater Interior

Crater Interior is a room in the Pyrosphere in Metroid: Other M. When Samus enters the room, the Lava will begin to rise. Samus must run through the room and reach the top. The fact that she does not have her Varia Suit coupled with the lava make the journey very difficult. Samus is authorized to use the Varia Suit at the top of the room, where she fights ULF 39.
