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.



  • When looting this weapon from the Experimental Weapons Drone, the weapon's icon will not show an error (like the regular Drone Cannon) but will instead be correct, showing Vault Boy wielding it as seen in your Pip-Boy, unlike the regular Drone Cannon.
  • The Drone Cannon Ex-B energy spheres do not bounce off walls. They will instead explode on impact, like missiles fired from a Missile Launcher, although they still fire in an arc.


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. NOTE: If you are having trouble finding this, do not be confused. There are, in fact, two places in the Weapons Lab where you can spawn Brahmin. The one with the Drone Cannon Ex-B is west, next to where the Alien Captive Recording is, not where the Weapons Lab teleporter is. Looking on your map the room is a triangular shape, with the top of the triangle facing west. There are three buttons in the room, one spawns the Brahmin and activates one Experimental Weapons Drone, the second button is located right next to the first and activates a second Experimental Weapons Drone (and in turn, spawns a second Drone Cannon Ex-B). The final switch is located next to the door with the force field and opens the room for you to go in. The Experimental Weapons Drones will drop a normal Drone Cannon on the ground, and have the Ex-B in their inventory.


  • When picking up another Drone Cannon Ex-B while having one in your inventory will sometimes turn both Drone Cannon Ex-Bs to normal Drone Cannons (Xbox 360, confirmed)
  • When shot, the projectile will occasionally pass through walls or the floor, doing nothing. (Xbox 360, PC, PS3 confirmed)
  • If the Console Command no clip (TCL) is enabled, firing the Drone Cannon Ex-B will result in the projectiles staying stationary. Because of this, it is possible to move around and place large amounts of projectiles for a larger impact. When no clip is disabled, the projectiles will then continue to travel to their point of impact. It is untested as to whether this works with the normal Drone Cannon.
  • When shot into deep water, the projectile will disappear without exploding, and then reappear and seemingly "float" in place on the surface without exploding. (Xbox 360)
  • 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. (Xbox 360)
  • In some accounts, when shot the projectile will just dissapear as soon as it hits the target, damaging the target, but not exploding. (Confirmed, PS3, PC,360)
  • On some occasions, the cannon will fire the projectile but will bounce of surfaces and not explode. (PS3)


The Drone Cannon Ex-B appears in the Mothership Zeta add-on for Fallout 3.
