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 - While the Ex-B does not have increased damage over the Drone Cannon, the projectiles fired from it travel in a straight line and explodes, unlike the bouncy Drone Cannon shot.

Obtaining
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])./ This may be a subtle hint about how the pip-boy 3000 cant scan alien technology. While in the Drone's inventory. However, the Drone Cannon Ex-B does have a picture.
