This is a large room in the middle of the Chozodia ruins. It is a long corridor with a low hanging ceiling, that drops into a lower vertical shaft. The room's central feature is a "pit" of four Zebesians, pacing back and forth below a bridge of Pit Blocks that have a delayed crumble. Samus must quickly crawl across the bridge, shooting Fake Blocks in her path, to avoid falling into the pit. If she does, she can climb out through the far right side of the pit after shooting a block. After the pit, Samus will run across a floor of Pit Blocks dropping her into the shaft. An alcove on the lower right of this drop has a fifth Zebesian in it, who may spot Samus. On a Perfect Stealth run, Samus can quickly shoot the left wall below the Pit Blocks and grab the ledge, then drop down when the Pirate is facing away from her and stun it. A demonstration of this can be viewed here.
The lower left floor of the pit is composed of Screw Attack Blocks, so Samus can also escape the pit that way once she acquires the Fully Powered Suit.
The room appears in a Japanese commercial for Zero Mission, showing Samus crawling through the pit with a Zebesian behind her.
