Brinstar Depths is a stage in Melee that can be unlocked by playing 50 battles in Versus Mode. It is also one of Samus's home stages.
The stage is a giant meteor that has one platform at the top and one at the bottom. Often Kraid, the giant monster in the background, will rotate the stage. The stage will then be at a different angle when it is rotated. This stage has no ledges no matter how it is rotated.
Brinstar Depths is illegal in both singles and doubles tournaments.
