I was recently looking into old games i use to obsessively play and vampire slayer(mod) for half life came to mind. Two teams, vampires vs. slayers. slayers have weapons but have to down and stake vampires for points while vampires have no weapons but speacial abilities, plus the usual drink blood for life and light hurts them. check it out food for thought.

I remember someone made a mod like this years ago, specificaly where you had to kill to stay allive.
