Environmental Test Floor

The Environmental Test Floor is a room in Pyrosphere in Metroid: Other M. It is a desert environment, and contains two Dessgeegas as well as a worm creature, presumably a Fune or Nahime. There is a large crane that can rotate a [{Grapple Point]], by taking damage from Missile fire at the end. Samus must use the Grapple Point to reach a platform with a Holographic Generator. This will reveal a door.
