BFG-9000 (Doom Eternal)



The BFG-9000 returns as a weapon in Doom Eternal, looking similar to its previous appearance but with more exposed parts. In this incarnation, it shares many similarities with its previous design, but lost the red colored areas on the top of the weapon. Unlike its previous appearance, it is now part of the wheel as a normal weapon. As far as it has been shown, it was heavily nerfed in both the campaign and Battlemode, being unable to kill a revenant player in the latter and an arch-vile in the former, but is still highly potent. Its targeting reticule appears to have a counter that keeps track of how many monsters it kills in a single blast.

The BFG-9000 is obtained in Mars Core as part of the BFG-10000 orbital defense weapon system.

Battlemode
The BFG is seen in Battlemode as a special weapon the Doom Slayer can use against the player-controlled demons.

BFG-10000
A BFG-10000 orbital defense weapon is present on the moon of Phobos. According to the codex, Samuel Hayden sent the BFG to the Phobos base for additional study, and it inspired the team there to create this larger weapon.
