The "twin hill corridor" is a room in Norfair. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission.


In Metroid, this is one of two corridors connecting the east and west green bubble shafts.

Similar to other corridors in Norfair, including the one directly above this room, it consists of midair platforms above a pool of lava that engulfs the floor. Most platforms are low enough that Samus can jump to them if she falls in. There is one elongated platform in the center of the room, consisting of two brownish red rock platforms joined by a patch of green bubble-like material. Atop this is an Air Hole that spawns Gamets. The ceiling is also partly constructed from the bubble material, with two stalactites formed out of the red rock tiles hanging from it.

In Zero Mission, the room's appearance has been significantly altered due to the increased memory of the Game Boy Advance. The lava has been reduced in level, and it is not possible to fall into it except for two Fake Blocks in the floor. A long walkway extends over the lava with two hills that sink into their center, and embedded into the center of each hill and the center is an Air Hole. Samus can run through this room in order to activate her Speed Booster, and then Shinespark from the base of the "east green bubble shaft" into the adjacent corridor.

This room, along with much of Norfair as it appeared in Metroid and Zero Mission, is no longer accessible in Super Metroid.
