The Main Reactor is a room in Agon Wastes in Metroid Prime 2: Echoes.


The Main Reactor is located in the Space Pirate base on Aether. It is where the Pirates keep most of their Phazon. The Main Reactor is where Samus engages Dark Samus for the first time. Dark Samus was absorbing the large Phazon crystal in the central Kellium energy reactor when Samus entered the room. During the ensuing battle, four of the tanks in the room (not the formerly mentioned tank) were destroyed. After the battle Dark Samus turned into Phazon particles and caused the covers of several tanks in the back of the room to come off, so Samus can see the Phazon within. Also the elevator in the room activated. To the left of the remaining tanks was a Spider Ball Track and a dead Luminoth, B-Stl. There is another Spider Ball track to the right of the former one that leads up above the tanks in the back of the room. The Dark Aether version of this room is the Dark Oasis.

Connecting roomsEdit


Missile Expansion
Samus must go up the Spider Ball Track that leads up above the tanks to the end of the track, and then use the Boost Ball to reach the tracks on the moving mechanisms above the tanks. Once Samus reaches the end, she must use a Bomb, Power Bomb, or a Missile on the hatch on the ground to destroy it. Inside is the Expansion.
