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


In both games, this room leads to the Screw Attack. In Metroid, the room is visually identical to the "Hi-Jump access corridor". It features a large lava pool with three midair platforms of metal brick suspended over it. Crawling along two of the larger platforms are a pair of Sovas, and Dragons inhabit the lava below. Their spitting projectiles make it harder to cross the room. On the other side of the room is a Red Hatch leading into the Screw Attack's chamber.

The corridor makes a brief appearance in the manga-strategy guide for the original game, Victory Techniques for Metroid.

In Zero Mission, the room has been significantly overhauled. It no longer contains any lava, and is set in a cave with partially constructed Chozo architecture. The floor has a pit in the center with a slight encroachment of cave rock in the middle, and a tall brown pillar on either side. A pair of pillars hold a Missile Tank above the pit. While the lava is gone, navigating the room is still a challenge as there are now rapidly-moving Ripper IIs flying through the room, which cause damage to Samus if they hit her. After she collects the Screw Attack, she can use it to kill the Ripper IIs, and break through the blocks in the ceiling to collect the Missile Tank.

This room is no longer accessible in Super Metroid. The Screw Attack is now obtained in the lowest part of Norfair, behind the Golden Torizo's chamber.
