Pretty obvious, wasn't it? They're putting on a big show, trying to scare us. Means we're getting under their skin. That's a good thing. Of course, now it looks like we've got a big Death Ray thing we need to take down before they blow up the whole damn planet. But it's nice to know we're having an effect, don't you think?


The Death Ray control is a location on board Mothership Zeta. It is a single large room serving as the control center for Zeta's death ray.


There are four power generators in the corners of the room. The player has to destroy them as a part of quest This Galaxy Ain't Big Enough.... The Death Ray itself is visible beneath the glass floor. The room has two teleporters leading to the living quarters and the Death Ray hub area.

The Death Ray can be fired from this room by using the buttons on the two consoles. The two buttons on the right aim the Death Ray to one of two pre-targeted locations. The buttons on the left (as the holographic "signs" appearing above them signify) bring one of the four generators out of the floor (button to the extreme left) and fire the Death Ray (second button from the left).

The generators rise out of the floor in sequence around the room starting at the left of the consoles. It apparently only takes one generator to power the Death Ray, as the other three do not rise when the Death Ray is fired (and the Death Ray will fire with only one generator left).

The Death Ray can be re-aimed at an unspecified target in Canada and fired multiple times, producing a spectacular mushroom cloud. Firing the Death Ray at Earth has no effect on Karma.

  • This is one of many areas of the ship that will not be accessible after the player has completed the main (This Galaxy Ain't Big Enough...) quest.
  • After destroying the 2nd generator in this room, approx. 5 aliens will appear from the teleport pad in the corner opposite to that generator.
  • When fired, the death ray initially strikes the Northeastern Great Lakes region, though as the resulting dust cloud expands, it eventually covers the general region of South Eastern Ontario, Western New York, and most of Michigan. The major cities of Buffalo and Toronto as well the natural landmark of Niagara Falls would be the closest to the devastation, assuming they still exist.
  • Despite no Karma being lost when the Death Ray is fired, it can be assumed that the player just committed an act that killed thousands of people.
  • When all 4 generators have been destroyed, the force-field door to the Living Quarters is opened.
  • The player can fire it multiple times at the same place and the crater gets no deeper, but dust still flies around the general area.


Death Ray control appears only in the Fallout 3 add-on Mothership Zeta.
