Drone Cannon Ex-B

The drone cannon Ex-B is a unique weapon added to Fallout 3 by the Mothership Zeta add-on and carried by experimental weapons drones.

Characteristics
The Ex-B is apparently an alien experiment in equipping the guardian drone model with a cannon that fires energy balls that explode on impact, instead of bouncing around. The Ex-B has a very long range if you manually angle the shot correctly. For example, you can be well outside Evergreen Mills and still hit the trapped super mutant behemoth. The Ex-B can also work underwater.

The drone cannon is an ineffective V.A.T.S. weapon, as the fired projectile will arc towards its target; since the game doesn't compensate for gravity in V.A.T.S., this can leave the projectile several meters away from its intended target.

The Ex-B can fire 417 orbs before breaking, the same amount of orbs needed to break a normal cannon.

Variants

 * Drone cannon

Location
In the Weapons Lab, there is a room where you can spawn brahmin for the drones to kill. Enter the room and kill the drone for the weapon. There is also a second one in the same room that is automatically activated when the first is destroyed.

Bugs

 * When shot, the projectile will occasionally pass through walls or the floor and do nothing.
 * In some accounts, when shot the projectile will just disappear as soon as it hits the target, damaging it but not exploding.
 * When shot into deep water, the projectile will disappear, and then reappear and seemingly "float" in place on the surface without exploding.
 * In V.A.T.S. mode, the Ex-B seems to aim like a normal drone cannon, landing short of the enemy as if expecting the projectile to bounce.
 * The Pip Boy recognizes the Ex-B as an unobtainable (obtainable only through console commands) weapon, evident in its picture (which is also missing).
