Frag grenade (Doom Eternal)

The grenade launcher (also known as a grenade cannon) 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 flamethrower. It fires a primed grenade that explodes, dealing splash damage. 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.
