Drone Cannon Ex-B

The  is a weapon which is added to Fallout 3 in the Mothership Zeta add-on. It is a unique Drone Cannon used by Experimental Weapons Drone.

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 short range because of that, and has no other features that differ from the usual Drone Cannon.

The Ex-B can fire the same amount of orbs as the regular Cannon; 417.

Locations
In the Weapons Lab, there is a room where you can spawn Brahmin for 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.

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

Bugs

 * When shot, the projectile will occasionally pass through walls or the floor, doing nothing.
 * In some accounts, when shot the projectile will just disappear as soon as it hits the target, damaging the target, but not exploding.
 * When shot into deep water, the projectile will disappear without exploding, 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.
 * Sometimes, the game screen will freeze when the cannon is looted from the drones.
