Phazon Site

The Phazon Site was a room in Metroid Prime 2: Echoes. The Site had an abundance of Phazon as its name suggests. The Site also had a large number of Dark Metroids. The room was connected to three other rooms, one of which housed the Sonic Boom upgrade. When Samus Aran first visited the Phazon Site, it was infested by Inglets. There were several scannable switchs in the room that Samus needed to deactivate in order to proceed to the next room. The room was located in Dark Agon.

Trivia
In the New Play Control! Metroid Prime 2: Echoes, the Impact Crater music plays instead of the Dark Agon Wastes music heard in the original version of Metroid Prime 2: Echoes.
