The Piston Tunnel is a tunnel in the Chozo Ruins. It is accessed from the Training Chamber and leads to the Main Plaza. The tunnel can only be accessed in the Morph Ball. Throughout the tunnel, there are a number of pistons which can lift Samus up or crush her. This tunnel lets out into the Main Plaza in an area where a Missile Expansion can be obtained.
