Vamps = Join for sure
Wolfs = Join if there are no vamps
Undead = Kill on sight. More fun if they don't move fast. I'm thinking sniper rifle, case of beer, pizza, roof top, lots of ammo. LoL
Make a stand and fight. My friends and I have our exit plans and defense plans all ready just incase. Now if vampires came around that would be a different story. I'd join them.
