The flame belcher is a shoulder-mounted side-arm weapon occurring in Doom Eternal. It shares its shoulder mounting point—one of the game's new features added to the Praetor suit—with the grenade launcher. It fires a short burst of flames that sets enemies ablaze, doing damage over a long period of time and stunning the enemies while they burn. By turning left and right while the flames are firing, the Doom Slayer can spread the damage out across multiple targets with a single use. As with other "third-arm" weapons that fire from the shoulder mount, killing enemies with combo attacks using the player's main weapon will reward the player with armor shards.
