Blood Oath

Jacob was a normal boy with a (somewhat) normal life. That is untill he found a mysterious rock. When he touches it, he bonds with a demon. Now he must find a way to remove the oath while he combats other demons. Accompanying him are his friends:

Michael
Main weapons: Dual pistols and Heavy Assault Rifle.
Bio: A kind hearted guy who you do NOT want to get in the way of when he's angry.

Meagan
Main weapons: Shotgun
Bio: Jacob's girlfriend with a knack for the shotgun.

Austin
Main weapons: Sniper Rifle
Bio: A prankster who is both loved and hated by the rest of the group.

Will they make it? Or will they perish in the heart of Hell itself?
