Ballista Storage

Ballista Storage is a room on SkyTown, Elysia. It appears in Metroid Prime 3: Corruption.

Description

The room's entrance hallway leads to a unique, spherical elevator that quickly descends to the room's lower floor. This floor includes a ledge and a large communication panel on three of the room's sides. The fourth side is adorned by a statue of a Chozo head. Under this statue, a locked door, powered by two turbines, is in place to prevent access to an Energy Cell. The turbines may be damaged if excess energy is supplied via the Grapple Voltage. The Defense Drone is battled here, and when defeated it rewards the Boost Ball.
