Brinstar

Brinstar is an underground complex of caverns and jungles on Zebes that appears in most Metroid games. Home to many creatures, Brinstar is used as a Space Pirate base. It is relatively easy to navigate. The area appeared in Metroid, Zero Mission and Super Metroid. It is also where Samus battled Weavel, severely injuring him.

Map
=Subareas= -Note- These names are only conjectural. They are for designating the different portion of Brinstar.

Upper Brinstar
The Jungle part. Home to many species of flora and fauna. Also the most maze-like. Home to Spore Spawn.

Lower Brinstar
The more straight forward part. The soil is red possibly because of the fiery heat of Norfair below. The main shaft of this area faintly pulsates a violet color, the source of this light is unknown. Also contains Kraid's Lair and Kraid himself.

Old Brinstar
The part where Samus enters in Metroid. The smallest part, it is explored early in the game. It is composed mostly of blue rock and ruins and is almost completely desolate. The security systems here detect Samus' presence after arrival and alerts the Space Pirates.
