The Air Lock is a room found at the start of Metroid Prime, the Frigate Orpheon. It is a small room connecting the exterior landing dock of the frigate to its interior. When it is entered, Samus must scan a panel to pressurize the room in order to proceed to further rooms. Later, while escaping during the reactor meltdown, the room depressurizes before the outer door becomes usable. When the frigate crashes on planet Tallon IV, this room is inaccessable along with many other rooms.

Dead Parasites can be seen floating in the Air Lock, along with other debris. They can be shot and destroyed, but not scanned. Pressurizing the Air Lock causes these objects to fall, indicating that the room and all others inside the frigate have an artificial gravitational field in place.

Trivia[edit | edit source]

  • Air locks are common plot elements in the Alien franchise, a series that influenced Metroid. In three of the films (Alien, Aliens and Alien: Resurrection), the protagonist Ripley flushed a stowaway Alien out an air lock during the climax of the film.
  • The "Intro Space" theme plays in this room.
  • Somehow, Samus does not seem to be affected by the lack of gravity in the room unlike the rubble and the Parasites, despite not having the Gravity Suit at that point in the game.
  • In Metroid: Other M, there is a room in the Biosphere which has a similar premise to the Air Lock. In this hallway, the door is locked, and when a Sensor is shot, the room is repressurized and the door unlocks.
  • When Samus enters the Air Lock for the first time, and the room pressurizes, she can still turn around and walk right back out to the depressurized areas. A more egregious case is during the escape sequence. The doorway to the Deck Alpha Access Hall is blocked by fire which somehow persists after the room is depressurized.
