The BFG in Doom 3 functions in a largely different way from its Doom counterpart. It is lost during the transits to and from Hell (where it is available as a pick-up), but the player manages to retrieve it again in the CPU Complex by taking it from the corpse of Sabaoth, who had stolen it from Campbell after leaving him fatally wounded. It is seen being used in Alpha Labs Sector 4 and Communications by Campbell, however, the player only manages to wield it starting from Delta Labs 2A. 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 considered one of the most powerful weapons in the game, only rivaled by the Soul Cube or the Artifact in Resurrection of Evil. The BFG 9000 (initials for ' Big Fucking Gun') of Doom 3 is one of the weapons created by the Union Aerospace Corporation under its weapon research programme.
