Materials Storehouse

The Materials Storehouse is a room in Cryosphere in Metroid: Other M. Samus Aran encounters MB, who refuses to believe that Samus is trying to rescue her. She also states that "her troopers are killing each other", showing a cutscene where Maurice Favreau is shot to death by another soldier. MB continues to run, but Samus pursues, until they meet a trooper (presumably Maurice's killer) utilizing a power loader. Samus deactivates the loader, and descends an elevator shaft to Pyrosphere.
