The BFG ("Big Fucking Gun")[1] is a fictional weapon found in many video games, mostly in id Software-developed series' such as Doom and Quake.

In that version, the BFG9000 released a cloud of 80 small plasma balls (randomly green or red) per shot, which could bounce off floors and ceilings.

However, it was scrapped as developer John Romero stated that it "looked like Christmas" and severely slowed the game down due to the large number of on-screen sprites.

In the Doom movie, the "bio force gun" fires a bright blue projectile that appears to burst on impact and spray a caustic substance over its target and the surrounding area.

[citation needed] The BFG is featured in Doom's 2016 reboot, but unlike in its first two appearances, it follows the mechanics of its Quake II rendition, firing a projectile that shoots beams at enemies.

[3] In that game's pinball adaptation, it is called the "Big Fancy Gun", and is the most powerful weapon that the Doom Slayer can obtain;[4] collecting it will grant the player an extra ball.

When the trigger is pulled, there is a pause of 30 game tics (≈0.857 seconds) before a large, relatively slow moving green and white plasma projectile is ejected.

The direction of the cone corresponds to the original shot, but it radiates from the player's current location at the time of the main projectile's impact.

[7] The behaviour of the weapon is similar to Doom 3's BFG: it can be charged in order to release a sphere of energy strong enough to vaporize a horde of soldiers.

[15] However, Elon Musk has explained that although BFR was the code name, he drew inspiration from the BFG weapon in the Doom video games.
