Zeta gun

The  is a unique weapon in Fallout 4 and a possible reward for completing The Secret of Cabot House.

Characteristics
The is specially modded Gamma gun that does a low amount of damage without any special radiation poisoning effect. It is also significantly weaker than the Lorenzo's Artifact gun that can also be gained as a reward for The Secret of Cabot House. Because of these facts, it appears that this weapon might be an intentionally weak weapon to be used as a "consolation prize" of sorts for siding with Lorenzo instead Jack (though siding with Lorenzo also gets the player a replenishable supply of the powerful Mysterious serum, which may more than compensate for the weakness of this weapon).

Like the Lorenzo's Artifact, this is actually a normal Gamma gun with a unique mod (the Zeta dish); it is possible for the player to build the standard dish mod to restore the Gamma gun's original power.

Variants

 * Gamma gun
 * Lorenzo's Artifact

Locations

 * If the player sided with Lorenzo, this will be found on Jack.
 * If the player sided with Jack, a Zeta gun can still be found in Cabot House.

Bugs

 * It is possible to get multiple Zeta guns by taking it the moment you enter Cabot House for the first time, then returning to the lab after being awarded Lorenzo's artifact and collecting another Zeta gun from the table. Following a period of time the Zeta gun reappears at the bench in Cabot House allowing you to acquire multiple Zeta guns.
