Time to cut this mother up, old school style.
You go back to your room and get your chainsaw. You make sure it's gased up and ready to go.
You kick the door down again and find the deadite twitching in the middle of the room. You turn on your chainsaw and grasp it tightly, ready to fight.
"You don't look so bad now, do ya?" You kick him in the gut and he spits up a white, vomit like substance. "Do you guys like fuckin' with me? Is that it? Do ya get off on it? Do ya? Huh?" You punch him on the back of the head and then lower the chainsaw, ready to slice yourself some meat.
As pull back your arm to make the deathblow the deadite quickly shoots it's arm up into your crotch.
You drop the chainsaw and fall over, holding onto your wounded groin. You look back over at the deadite and see him run out your front door. You grab the chainsaw and instinctively run after him. As you reach the door you see him taking the staircase.
