Death Ray

The death ray is the giant alien raygun attached to the underside of the Mothership Zeta. It appears to be its main offensive weapon. The Lone Wanderer uses the ray to destroy an alien enemy ship, which begins to attack Zeta shortly after the hero hijacks the vessel.

History
The Lone Wanderer first encounters the death ray when he reaches the observation area. A giant alien head will appear as a holographic display, speak angrily, then a little while later a very loud noise will be heard and if one looks down they will see a large beam cross the see-through floor.

Shortly after, the quest This Galaxy Ain't Big Enough will begin and the destruction of the death ray will become your major objective.

Use of the Death Ray

 * Shields: Most of the ship's energy is dispensed to the shield, giving you extra protection but weakening your Death Ray.
 * Intermediate: The ship's energy is dispensed equally amongst the shields and the Death Ray. This is the initial stance.
 * Powerful Ray: The ship's energy goes to the Death Ray, severely weakening your shields but giving your Death Ray much more power.

The options are, respectively, from the right to the left on the console. Use the button in the middle to fire. It takes roughly five seconds to charge each time and its ability to fire will be shown through the button lighting up and spinning.

Appearances
The gun appears in the Fallout 3 add-on Mothership Zeta and is used in the quest This Galaxy Ain't Big Enough...
