The Generator Shaft is a long shaft (roughly 16,700 m) below Generator C in Metroid Prime 3: Corruption. It is located on Norion. After Meta Ridley surprises Samus in the Generator above, the two fall down this shaft, where they battle each other to be the last to die. The battle is timed, and if Samus does not defeat Ridley before she reaches the bottom of the shaft, then a Game Over will result. Samus, however, does successfully defeat Ridley, and jumps off of his body as Rundas saves her from a certain doom.
