Instructions
Throw the Bowie knife and the Ballistic knife at the Hellhound when it stops momentarily before lunging into an attack. Throwing both knives will kill the Hellhound.
Equip the Trench Gun. This gun kills the Hellhounds on the first hit. Small packs of Hellhounds may be destroyed with quick aiming.
Use the Ray Gun on small packs of Hellhounds. This gun is very effective when Hellhounds are at a distance.
