The BFG 9000 fires a green burst of plasma, damaging enemies near the projectile during flight and vaporising targets upon impact, as well as causing significant splash damage to enemies standing in the vicinity of the projectile's explosion. The BFG 9000 is the most powerful weapon in the game, as it is able to kill any non-boss creature in a single direct hit. However, bosses can be stunned with one direct hit for a few seconds, which can be used to break up an attack. The weapon is very useful in dangerous situations or against a large group of powerful creatures.
