Echo Gate

Main Research

An Echo Gate is a device in Metroid Prime 2: Echoes that uses a sonic security system. In order to open these, the Echo Visor must be acquired, as well as the Annihilator Beam. The locks are easily recognized by a "key" symbol while using the Echo Visor, and are in the shape of small terminals.

To unlock the Echo Gates, Samus can first shoot the Echo Gate itself to release several "echoes" of different pitch. Samus must then find and shoot the Echo Key Beams in the order in which the "echoes" sounded. Each Echo Key Beam has its own "echo" corresponding to the ones made by the Echo Gate. However, if one lock is unlocked out of order, Samus must restart the unlocking sequence.
