Now you're gonna have to go outside of the ship. I know it looks scary, but that's the only way to the top. Oh! Make sure you wear a spacesuit before you go out there or you could die! Don't forget!Sally

The space walk is a location outside of Mothership Zeta in 2277.


The space walk cannot be entered without the spacesuit being worn. The player character cannot use the Pip-Boy or use any weapons on the map. There are no enemies, although the Lone Wanderer can see some aliens scurrying around the corridors below them. The player character must locate three panels that stand out slightly from the ship's hull. They are emitting a yellow glow to make them obvious. Activate all three panels and the transporter to the next portion of the ship will become available. The transporter is located directly in the center of the circular hull the player character is traversing.


  • This is one of many areas of the ship that will not be accessible after the player character has completed the main quest This Galaxy Ain't Big Enough....
  • The space walk is a one-way trip. The player character cannot return to the airlock they emerged from; they must use the transporter to proceed to the next level.
  • If the player character attempts to walk off the edge, they can see an animation of the Lone Wanderer floating off into space while trying to grab onto the ship's hull.
  • The Earth below the player character cannot normally be seen from the space walk, although they will have an opportunity to view it through a floor window later. The only way to see the Earth from this vantage point is by using the console command tfc. The sun cannot be seen anywhere, despite being visible from one of the windows inside the ship.
  • If the player character has a drone following them it will not follow them on the spacewalk. Once they have reached the final teleporter, it will teleport with the player character.
  • A second before the player character starts walking, it will show their oxygen level and say 1 rad p/s.
  • If the player character looks through the transparent parts of the floor, they can see two aliens running in a continuous loop around the ship. They can also hear their shoes squeak, even though there should not be any sound in space.
  • The Pip-Boy and Pip-Boy glove are visible in third-person.
  • If the Pip-Boy glove is removed via console, the spacesuit glove appears larger on the left hand than the right.
  • While outside, the player character can turn the Pip-Boy light off, although they cannot turn it back on.
  • Normally, the Pip-Boy, and with it the local map, isn't accessible. It can be activated by a console command though. On a PC, type enableplayercontrols 1 1 1 1 1 1 1.


The space walk appears only in the Fallout 3 add-on Mothership Zeta.


PCPC After re-entering the ship through the top, the compression chamber may display "This door cannot be opened until the decompression sequence in completed". Every time the player closes it, it pops up again preventing action such as forward movement. If one comes across this, keep closing it while pressing forward, get to the activation panel ahead and activate it, just keep pressing okay to close the pop up, once the room fully is compressed the pop up stops.
