Drone Cannon

The  is a weapon of alien origin which is added to Fallout 3 in the Mothership Zeta add-on.

Characteristics
It is the removed arm cannon of a Guardian Drone. It fires a ball of energy that acts as a grenade, bouncing and then exploding after a period of about 3 seconds. The projectile has the ability to move buses and cars before exploding. This weapon is hard to use at first, but once you understand its operation, it becomes an extremely devastating weapon.

When fired into water, the projectile will continue normally, bouncing off any obstructions under the water. It will explode normally like other explosives.

Variants

 * Drone Cannon Ex-B: It has increased range over the Drone Cannon, and the projectiles fired from it explode on impact while still arcing, unlike the bouncy Drone Cannon shot.

Locations
This gun can be found on Guardian Drones along with Alien Power Modules to power them. The cannons can also be shot off the drones and picked up like other weapons.

Appearances
The appears in the Mothership Zeta add-on for Fallout 3.

Bugs

 * When taking the cannon from a drone, it has no icon (PipOS Error - 404 [File Not Found]).
 * When examining a cannon dropped by a drone in the normal worldview (not by searching the drone's inventory), it will always show a value of 999 caps (app. half CND) regardless of the weapon's actual quality.
