The BFG9000 (initials for "Bio Force Gun" or "Big Fucking Gun") of Doom 3 is one of the weapons created by the Union Aerospace Corporation under its weapon research program, and is considered the most powerful weapon of the game, capable of causing damage to a single enemy for more than 1700 hit points. It is first introduced in UAC Administration, when Campbell opens his suitcase to an unknown green glow (green being associated with the colour of the BFG projectile). It is seen being used in Alpha Labs Sector 4 and Communications by Campbell, however the player only manages to wield it at Delta Labs 2A. It is lost during the transit to the Hell level (where it is available as a pick-up), but the player manages to retrieve it in the CPU Complex from Sabaoth, who had killed Campbell and taken it from him.
The BFG in Doom 3 mostly functions in a different way from its Doom counterpart, as the projectile exists in the form of a computer chip contained within a ball of relatively slow-moving green plasma. The newer version also follows a charge-based system; holding down the trigger causes the weapon to charge up for a more powerful shot (up to 4 levels of charge), the status of the charge being displayed on a small monitor (which also displays the ammo count and dispenses the game HUD, just like newcomer Machine Gun, the Chaingun and Plasma Gun). The chip identifies and shoots rays at opponents that will debilitate them prior to the explosion of the plasma projectile. The damage of these rays is 200 (over 10 points per second). The effects of the weapon are devastating; a single-charged projectile can obliterate any weaker monster, whereas a fully-charged shot will kill any monster up to a Vagary. "Elite" monsters with a lot of hit points such as the Hell Knight or the Mancubus generally require a double or triple-charged shot to kill, and this weapon is ideal for taking out Arch-Viles quickly, when the Soul Cube is not available.
Unlike in the classic Doom and Doom II, the BFG9000 in Doom 3 no longer uses the same ammo as the Plasma gun, but its own type of cell instead. The BFG Cell exists as a green cylinder with an actively vibrating sphere inside (similar to an atom), and holds 4 charges. Unlike in Doom II, BFG cells are very hard to come by and are placed in relatively obscure locations, and it is therefore recommended to use the weapon sparingly.
Based on security chief's report, this BFG is lighter than "previous version" (hinting an older version or a predecessor). The weight saving may be credited to reducing the projectile energy capacitor or containment field. This noticeably reduces weight but also makes the user more vulnerable as excess energy may detonate should the containment fail. The ammo is reloaded from a magazine compartment located on the left side of the weapon. The green plasma orb serving as the weapon's power source may be related to the green glowing chemical dump of the energy production (fusion process in this storyline produce steam and green sludge) process utilized in Mars. This is starkly different from the energy canisters used on the plasma rifle as it stores a glowing bright blue mass of energy, which is presumably a main product of the energy facility (EnPro), explaining the abundant supply of plasma energy bottles in the EnPro facility. The BFG ammunition itself requires specialized chips to control detonation, preventing mass production of the BFG cell. It is possible that the Mars facility was planned to be designated as the BFG's ammo production plant (one of the reasons why Swann was authorized to have a "hard hand" policy on Betruger).
The weapon is recommended for medium to long-range combat, as firing at a monster up close will severely damage the player due to the weapon's blast radius. Moreover, the longer the projectile exists undetonated, the longer the time it will have to attack other enemies within the vicinity with its rays. The BFG is also recommended for usage in areas with heavy enemy presence due to its targeting system, as the other weapons specialize more in single-enemy combat. It is also advisable to deploy the weapon for boss fights, such as in Caverns 2, due to the heavy premium on the ammunition. Do not overcharge the weapon, as it can overheat and explode, killing the player instantly.

Informational video on the BFG 9000
Representing the pinnacle of UAC research and design, the BFG 9000 is the most advanced firearm ever designed. Fully self contained and deployed is a handheld platform it is capable of an excessive amount of fire power. The BFG 9000 contains sophisticated friend or foe technology that discriminates targets in real time.
Each projectile contains a small but very powerful computer core that actively maintains targeting and delivers a stream charge down each beam to soften targets before detonation. The detonation stage of the projectile is devastating. Targets within 15 meters of the flashpoint are not likely to survive.
While not recommended for small quarter combat, the BFG 9000 is ideal in the field and against movable targets. The only foreseeable defense is small arms ballistics. If the projectile is destroyed before exploding, the computer core cannot process the final fusion reaction, resulting in a less than optimal detonation. For more information contact the UAC's Advanced Weapons Department.
- Be careful when using the BFG in narrow areas. The blast from a direct hit will injure the player if too close, and is more damaging if charged.
- Strangely, when shooting at the floor, wall or obstacles, the player won't take any damage from its blast. It's very common to shoot there if you feel you're afraid of it.
- Sabaoth's BFG cells' impact against a wall doesn't deal blast damage to the player.
