BFG9000



The BFG9000 appears as a large, solid metal gun which fires large balls of green plasma. For general purposes it can be considered the most powerful weapon in the game.

Combat characteristics


When the trigger is pulled, there is a pause of 30 tics (about 0.857 seconds) before a green and white plasma ball is ejected. If it hits a creature, when the creature is close to other creatures, the plasma ball won't only kill the creature the BFG9000 is aimed at, but also kill the creatures the creature is close to. If the large plasma ball hits a solid object, it explodes and causes 100-800 hit points of damage to the target, in round multiples of 100.

After a further pause of 16 tics (about 0.457 seconds), additional damage is calculated: 40 invisible tracer rays are emitted by the player in a cone-shaped area (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 &mdash; 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 ray causes 49-87 points of damage 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 minimal damage of the weapon is 49 points (if an object is hit by one ray and not the plasma ball) and, hypothetically, the maximal damage is 800 + (40 &times; 87) = 4280 points (if 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, that much damage can still 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).

Tactical analysis
Despite its tremendous power, the weapon can be used correctly only with practice, due to its staggered firing sequence and nonstandard blast damage. The BFG FAQ includes an extensive section on deathmatch tactics.

Data



 * 1) 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.
 * 2) Assumes that direct hits are possible, which does not occur in any stock map.

Appearance statistics
The IWADs contain the following numbers of BFG9000s:

The BFG in other id Software games

 * Doom 64 includes a slightly revamped version of the BFG. Upon being fired, it will make a computerized whirring sound increasing in pitch until the projectile is shot out. When the projectile hits an enemy or wall, it will create a cone-shaped field of damage from its detonation point back to the player, killing or hurting any monsters in its path.
 * 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. Unlike Doom's BFG, however, a point-blank blast will kill the player as well as his intended target.
 * Quake 3 Arena included a new version of the BFG 10K that works considerably different then 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 (similar to the Quake II BFG 10K).
 * The BFG also appears in Doom RPG, where it is named BFG-9000.
 * Rage includes a weapon called the Authority Pulse Cannon, which normally acts as a sort of energy-based minigun, but also features the ability to fire an alternate ammo type called "BFG Rounds", which do devastating damage to targets within range.

Other appearances and homages
Many subsequent first-person shooters implemented similar weapons, but few were quite as notorious as the BFG9000. In addition, due to its reputation, the BFG has been referenced or parodied in many other places:
