Although only five versions of the BFG exist, we here at the Union Aerospace Corporation’s Advanced Weapons Division have gone through countless different blueprints and design plans, the following are the only versions that have been built so far.
Fires a large blue ball of plasma capable of melting even the strongest of steel, but is big and bulky, has a nasty kickback and takes too long too reload.
Rapidly fires many small green and red ball of plasma and had a similar design as the 3.14, but was scrapped before it left the drawing board. However, before the blueprints could be destroyed, a civilian somehow got his hands on them and -- ignoring laws -- decided to build it. The civilian fixed the problem of the nasty kickback by giving it a new body. The barrel had been drastically changed and the solid stock replaced with a collapsible one making it a little less bulky. The collapsible stock acts like a shock absorber when locked in place, reducing pressure on the user’s shoulder. However when fired, half of the shots would miss the target completely, rendering it not cost-efficient, which is the reason why it was scrapped in the first place.
Combining the best of the 3.14 and the 2704 models; this one fires a large green ball of plasma capable of eliminating all targets within the 7.5M blast range. Unfortunately, due to an unavoidable flaw in the design, it takes too long from the time the trigger is pulled till the time it charges the shot and finally fires.
Although it still takes too long for it charge the shot and fire, it makes up for it by having no stock, and being a little more durable, compact, and lighter than previous models.
Currently the latest model out, it’s the most durable and lightest of them all and gives the user the option of firing four uncharged or one charged shot(s). At the core of the plasma ball is a microchip with sophisticated Friend or Foe technology that sends a charger beam at nearby targets, softening them before detonation. Anyone within 15M of the blast range is not likely to survive. The only problems with this model are if something were to destroy the microchip before detonation, it will result in a less then optimal explosion and over-charging a shot which will result in the weapon exploding and killing the user and anyone near them.
