Drone Cannon

The Drone Cannon is a weapon of alien origin in the Fallout 3 add-on Mothership Zeta.

Gameplay
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 one understands its operation, it becomes an extremely devastating weapon. A direct hit from the ball of energy will also deal high damage, and hitting a target's middle to upper body will usually result in the ball dropping straight down before exploding, making it a good way to hit specific targets with the explosion.

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

Durability
The Drone Cannon can successfully fire about 417 times from full condition before breaking.

Variants
Drone Cannon Ex-B - it has increased range over the Drone Cannon, and the projectiles fired from it explode on impact, unlike the bouncy drone cannon shot.

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

Bugs

 * When taking the cannon from a Drone, it has no icon (PipOS Error - 26 [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.
 * When examining the Drone Cannon while in a Guardian Drone's inventory, the condition, damage, and value is at its highest (Full CND,152 DMG, Value:1999 caps) but when examining the Drone Cannon in the Wanderer's inventory, it will show its true statistics e.g. 3/4 CND,129 DMG, Value:1357 caps.
 * If one equips a Drone Cannon while wearing Enclave Tesla armor, the coils on the back of the chest piece will disappear.
