Cargo Hub

The Cargo Hub is a very large room on Norion in Metroid Prime 3: Corruption. It connects to a few different rooms, one of them being Control Tower Access. It has several dead Galactic Federation Marines in it. A small hatch can be opened by a Hand Scanner, which leads into a maze underneath the floor.

Trivia

After getting the Missile Expansion and leaving the ventilation shafts, Samus can become stuck in opposite wall if she un-morphs at the correct time. Samus will be unable to move from the position and will be dealt continuous damage.
