Corridor No. 3

Corridor No. 3 is a room in Brinstar in Metroid and Metroid: Zero Mission.

Description
In both appearances, Corridor No. 3 consists of green blocks and metallic structures. With the higher graphical detail in Zero Mission, the green blocks appear artificial compared to the natural blue rocks of Brinstar. There are several long horizontal silver tubes infested with Zoomers, which Samus Aran must carefully navigate in Morph Ball mode.

Corridor No. 3's most significant feature is a small room located about midway through the corridor. Samus can shoot straight up to break through the ceiling, leading to a hidden room above Corridor No. 3 that contains the Varia Suit. The High Jump Boots are normally required to reach the Varia Suit, though Samus can prematurely acquire the Varia Suit by Bomb Jumping or freezing an enemy with the Ice Beam to use as a platform.

At the far end, Corridor No. 3 connects to a vertical shaft, where Samus can enter Corridor No. 4 or the room containing the Bomb.
