Drone Cannon Ex-B

The drone cannon Ex-B 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 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 Drone Cannon Ex-B can be used against targets underwater. Making effective sinking bombs against cowardly Mirelurks. It however is a uneffective VATS weapon, as the game dosen't compensate for the attacks following gravity. So if you target an enemy a distance away, it will explode half way there.

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

Variants

 * Drone cannon

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.

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.
 * The pip boy recognizes the ex-b as a unobtainable (obtainable only through console commands) the picture is the same.
