BFG9000/Doom 3

The BFG 9000 of Doom 3 is the ultimate gun. Based on Quake II’s BFG10K, the BFG (acronym for "Big Fucking Gun") shoots a slow-moving ball of green plasma that contains a small computer chip. This chip identifies and shoots rays at opponents before the initial explosion that will kill most demons near the blast. Shooting the chip induces a less than optimal explosion. This version of the BFG can be charged up (consuming up to all four charges in the gun) to deliver an even more powerful blast essentially capable of destroying any non-boss monster it makes contact with. If charged for too long, the gun will explode, killing the player. The ammo counter is located on the weapon.
