Defeating ImpsIf the Imp is jumping at you, blast it while it is in the air with the shotgun to kill it in one shot. This is slightly difficult to time.
Additionally, as soon as an Imp has thrown a fireball at you, strafe around it with your shotgun equipped. Get very close to the front of the Imp and blast it in the chest.

Shoot it with the rocket launcher. Do this a few times and he will die easily.
