I was just throwing Ideas out there.
Ok, so we have a Vampire bandit Chieftan who we've been hired to kill. Is the leader a he or a she? Are the blood bandits holed up in a cave, fort, ruin or abanoded Village? Do we want to just charge in and kill everyone? Or just kill the Vamp?
Once we know that, we can start RP'ing. Also, I vote a cave. Vampires and assasins both like to fight in caves.
Also, these bandits. Let's assume they have Near human AI's. No "Oh, I got shot in the face, but I don't see anyone, so i won't tell my buddies to look for an assasin". Stupid Computers.
