The BFG 10K or simply the BFG is a firearm that can be accessed by pressing "9" on the NumPad or scrolling manually. It is essentially an upgraded version of the Plasma Gun. It hurls giant slugs of Plasma at enemies, usually killing in one shot. Despite this, it isn't automatic and takes half a second to recharge. It isn't as flexible as the Plasma Gun, but a lot more deadly. This is one of the rarer weapons, and usually isn't found at startup.
