Piston Hall

The Piston Hall is a room on SkyTown, Elysia. This room leads from Turbine Access (Which leads to the Turbine Chamber) to underneath the Concourse. In the middle of the room there is a gap, which will hurt Samus if she falls through it. On the other side of the gap is a wall which rotates around a small circular section of the room (In Metroid Prime Trilogy, the rotating wall is replaced by an energy field). The wall alternates between blocking Samus from reaching the other side, or blocking samus from leaving the section of the room. Samus must time a Screw Attack carefully in order to avoid hitting the wall and falling into the gap.
