conserve ammo get a hand full of wooden stakes and a garlic neckless or was that vampires ?
that how you kill vampires in the day time when there sleeping. At night on any vampire besides a master class reg . ammo will work just take more of it. dead sea or blessed salt shells ,silver bullet blessed by a priest,holy water or holy earth shells(eath from a holy site like places of worship) all will help out on any un-godly things you run across. It the god/ Faith and confident belief and trust that give it power over evil. God has no religion blocks, it does not matter if it's Baha'i, Buddhism, Christianity, Confucianism, Hinduism, Islam, Jainism, Judaism, Shinto, Sikhism, Taoism, Wicca, Zoroastrianism, or Druidism.
If it's of the light then it will work on the evil as long as you belive in it. Also head shots are always best and after you kill it or it's down use fire to make sure it down for good. Zombies head shot or cut off the head. Rember this If You Kill the Brain,Then You Kill The Ghoul And It's Motor Functions. Aim For The Head. Other then a head shot even if it hits a land mine or bio weapon it not going to stop. It only has one goal in life and that is the need to feed. It's a meat seeking missile.
