The Thirst Zapper is a weapon in the Fallout 4 add-on Nuka-World.


The Thirst Zapper is a water shooting weapon, in the shape of a Nuka-Cola bottle. This weapon is needed for shorting out Colter's power armor.

It can also be used in three of the Nuka-Cade games as the weapon for the Bandit Roundup game, Whac-a-Commie or the Nuka-Zapper Race.

The basic Thirst Zapper has unlimited ammunition in a sense, unequipping and re-equipping the Thirst Zapper adds a bottle of ammunition to the Sole Survivor's inventory. Upon re-equipping the Thirst Zapper, they can then fully reload it with a bottle that appears similar to the ammunition produced for modified Thirst Zappers.

Finding the Project Cobalt schematics will allow the Sole Survivor to upgrade it into a functional and deadly weapon.

The weaponized Thirst Zapper, when used in V.A.T.S., will home in on enemies as if it had the missile launcher's targeting computer.
