Brinstar Depths
Brinstar Depths is a part of Brinstar in the game Metroid. It was the location of Kraid's hideout. It also appears as a stage in Super Smash Bros. Melee. As the name suggests, it takes place underneath Brinstar. The stage starts off on a large floating rock type platform (players stay here the whole time). This main part of the stage is surrounded by a few smaller floating rocks, which players can jump onto. However, this may be dangerous, as the rocks are small.
Every once in a while, Kraid will come into the background. He will knock into the platform, making it turn. This can be very dangerous, as the player could end up falling off by accident. Very rarely, the platform will tilt all the way around in one go. Kraid can also rarely hit a player if he or she is in the way of the slash. Other than that, there aren't really any other gimmicks worth of note.
