BFG

Noun;
"Big Fucking Gun" (also may be referred at the Bio-Force Gun). A fictional weapon that can be used in the Doom and Quake series, both developed by id Software. The weapon is capable of dealing massive damage to a high volume of demons. In Doom: The Dark Ages, it's counterpart is the BFC (Ballistic Force Crossbow), which retains the same ability as Doom 2016 and Eternal's BFG9000.

The Slayer's affinity for guns is so apparent, that Dr. Samuel Hayden knew he'd take the BFG9000
