Tesla Cannon (Fallout 3)

The Tesla Cannon is a weapon which will be added to Fallout 3 with the release of the Broken Steel downloadable content pack in May 2009. The quest line of Broken Steel includes having to find the parts for this weapon in order to help the Brotherhood of Steel build it.

Characteristics
The Tesla Cannon fires extremely powerful blasts of electricity, apparently capable of knocking aircraft out of the sky with one shot, balanced by a long reload time. It is likened to Quake's railgun, vaporizing enemies in a puff of smoke on contact. Judging by pictures of it, it seems it will use ECPs.

Trivia
The Tesla Cannon was also to be featured in the canceled Fallout: Brotherhood of Steel 2, bearing a striking resemblance to the weapon in Broken Steel. Described as a "high-powered mass-cannon throwing tesselated plasma forward in an orgy of death and destruction" in the FO:BOS2 design document, it was to be the so-called "uber-weapon" of player character Maxus. "Uber-weapons" were to be unique weapons for each PC which had to be assembled from 5 parts over the course of the game. One of the five parts for this weapon was a Tesla Coil; in Broken Steel a Tesla Coil is where one or all parts for the Tesla Cannon are supposedly found.
