You are now playing the Vampire Academy game. You should also play one of the other Thinking Games at GoodGame.co.in !

Transform all human beings into vampires by moving vampires to strategic spots. Each vampire moves in a certain direction, so that you use their direction optimally. Watch out: when a vampire runs across a priest, he'll stop.
