Generator Shaft
From Wikitroid, the Metroid wiki
The Generator Shaft is a long shaft below Generator C in Metroid Prime 3: Corruption. It is where Samus fights Meta Ridley. The battle is timed and if the player doesn't beat Meta Ridley on time, Samus will die. It is located on Norion, and it is roughly 16,400 feet long, and the fall takes just over 4 minutes. If the player defeats Ridley in the alloted time amount, then Rundas catches Samus, and saves her while Ridley falls to the bottom of the shaft.
