Metroid Quarantine A is a room in the Phazon Mines. It appears in Metroid Prime.


This room contains multiple Space Pirate terminals. Its main purpose is to quarantine Tallon Metroids. A large Force Field blocks off two-thirds of the room. The scannable switch in near the door to Quarantine Access A. The opposite side of the room contains four Tallon Metroids and large amounts of Phazon. There is a large gap near the Force Field. Samus must have the X-Ray Visor to be able to see the two moving platforms. There are many fungal growths which have been mutated by Phazon. When first entering the room from the Quarantine Access A side, a short cutscene will play, in which the camera pans to the Force Field. Two Space Pirates and two Tallon Metroids are visible.

On visits after the Force Field is deactivated, the room will become dark.

Connecting rooms[]


Samus engages a Metroid at the room's entrance.


Missile Expansion
After crossing the two invisible platforms across the gap, Samus must jump onto and off of another invisible platform to a Bendezium wall. After Samus lays two Power Bombs (There are two walls), Samus reveals a Spider Ball bridge. After following this and another invisible platform, she can get the Missile Expansion.

  • Near the entrance of the room, there is a console that is able to be scanned that releases the Metroids. If Samus hasn't killed the Space Pirates in the room yet and scans it, the Metroids will kill the Space Pirates. Metroids will also seek out and kill Space Pirates in some areas when brought in contact with them, like in the Phendrana Drifts Pirate base.
  • Near the large console below the entrance door, there appears to be a Hand Scanner similar to those found in the Pirate Homeworld.
  • An unused version of the room contains Phazon Blastcaps, which are never used elsewhere in the game.
