The Undersea Volcano is Master Albert's underwater hideout, which can only be accessed from a Transerver in the Bio Lab. All pieces of Biometal Model W collected by Albert are kept in this area. After finding Albert, Prometheus and Pandora suddenly kill him, and they fight against Ashe/Grey. After Pandora and Prometheus are defeated, Model W absorbs data from them and they collapse. Albert appears and reveals that they had killed a decoy, and Model W begins to merge, forming Ouroboros. The hideout is destroyed during Ouroboros' rise, and the Undersea Volcano can't be accessed again.
