"When it appears that you have killed the maniac/spirit/demon/creature, DO NOT check to see if he/she/it is really dead. Keep hacking at it until it is in pieces small enough not to be a threat to you. If you've shot at it, shoot it again in the head, and remember, shoot till it stops moving, and then keep shooting till you're out of ammo. Then reload and shoot it some more. Then set it on fire and burn it up, this works with everything except demons and spirits. Then get the heck out of there..."

All of that didn't seem to work on Jason, he just kept coming back, half melted hocky mask and everything...
