Template:Doom 3 weapon also in The BFG9000 is the ultimate weapon to be found in Doom. It appears as a large, silver metallic gun with a dark gray aperture similar to the plasma gun, and fires large spheres of green plasma. In general, it can be considered the most powerful weapon in the game; it is capable of destroying nearly any player or monster with a single shot, and can disperse damage over a wide area to multiple targets simultaneously.
The abbreviation "BFG" canonically expands to big fucking gun, as explained in section 14 of the Doom Bible. Other expansions of the name were attributed to it before that document was made public, notably "big fragging gun", which still retains some usage in settings which require politically correct language. Characters in the Doom novels refer to the BFG as a "big freaking gun". In the Doom movie, BFG is said to stand for "Bio Force Gun" , although Sarge refers to it with much relish as a "big fucking gun". It is also sometimes called the "Blast Field Generator."
When the trigger is pulled, there is a pause of 30 tics (approximately 0.857 seconds) before a large, relatively slow moving green and white plasma ball is ejected. If this plasma ball hits a solid object, it explodes and randomly deals between 100 and 800 hit points of damage to the target, in round multiples of 100.
After a further delay of 16 tics (approximately 0.457 seconds), additional damage is calculated: 40 invisible tracer rays are emitted from the player in a cone-shaped volume (about 45° half-angle) in the direction the plasma ball was fired. If the player has turned around, the direction of the rays does not change — they are still traced in the direction of firing of the original plasma ball. If he has moved to another location, their origin moves along with him. Each of the rays causes random damage between 49 and 87 points if it hits a solid object within 1024 map units. Even cyberdemons and spiderdemons, which are immune to blast damage, are affected by these rays.
Therefore, the minimum damage of the weapon is 49 points if an object is hit by one ray and not the plasma ball. Hypothetically, the maximum damage is 800 + (40 × 87) = 4280 points, which assumes the plasma ball hits an object for full damage, and all 40 tracers also hit the object for full damage. However, even should all 40 rays and the energy ball hit a single target, this theoretical maximum damage can never actually be inflicted due to the periodicity of the simplistic pseudorandom number generator used by the Doom engine.
Contrary to section 3H of the BFG FAQ, the tracer code does not include horizontal auto-aiming (although, like any bullet attack, each tracer can auto-aim vertically).
Despite its tremendous power, the weapon can only be used to its fullest effect with practice, due to its staggered firing sequence and the unique behavior of the tracer ray cone. The BFG FAQ includes an extensive section on deathmatch tactics.
- As with the rocket launcher and chaingun, the full BFG sprite (after pickup) is slightly too large for the screen, and can only be viewed with a level or resource editor; the lower edge of the sprite includes a BFG logo.
- In the Doom Bible, the section on weapons (14) describes the BFG 2704, a highly destructive weapon which would damage the wielder a bit, pushing him back. That same entry unveils the politically incorrect meaning of "BFG". Tom Hall later used the number 2704 as the year of the setting for his game Terminal Velocity.
- By the press release version of Doom, the BFG was a functional, albeit completely different, weapon: each shot in that version releases 80 regular-sized green and red plasma balls (spending 40 cells per shot) which can bounce off ceilings and floors. This version was scrapped because, according to John Romero, it "looked like Christmas" and severely slows the game down due to the large number of sprites on the screen. MBF, a source port that can play the press release levels, includes a working restoration of the press release BFG.
- The BFG9000 has a "safety catch" similar to the rocket launcher. When selected while the fire key is still pressed, the BFG will not begin firing immediately like other weapons, but only when fire key is released and pressed again. The safety mechanism was likely implemented to prevent the player from wasting 40 cells by accident.
- To determine the damage of a BFG tracer, a random number between 1 and 8 is generated and repeated 16 times. This makes the total damage vary from 16 to 128 (due to the "bell curve" phenomenon, the value is weighted towards the middle of the range). However, due to the pseudorandom number generator of Doom, this never happens in real gameplay, and the damage is limited to the range of 49 to 87.

- This table assumes that all calls to P_Random for damage, pain chance, impact animations, backfire checks, and muzzle lighting are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as flickering lights). It is also assumed that all projectiles are launched at nearly the same range, so that the various procedures call P_Random in the same sequence each time. Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
- Assumes that direct hits are possible, which does not occur in any stock map.

The BFG in other id Software games
- Doom 64 includes a slightly revamped version of the BFG. Its modified damage characteristics and timings are inherited from the Atari Jaguar version of Doom.
- Quake II features the BFG 10K. In addition to the direct impact damage, its slow moving plasma projectile shoots green beams which lash out at any enemies near it. The projectile sprites are exactly the same as Doom's.
- Quake III Arena included a new version of the BFG 10K that works considerably different from its previous incarnations. It fires explosive plasma projectiles in a high rate of fire and has a more streamlined shape.
- Doom 3 includes a redesigned version (see BFG 9000 (Doom 3)). It can be charged up for a more powerful shot, and the plasma projectile shoots rays at nearby opponents in a manner similar to the Quake II BFG 10K.
- The BFG also appears in the Doom RPG, where it is named BFG-9000.
