A suggested Zombie game, which I think is fun

The Game is a bit like an RPG (Role playing game) or something along those lines. What you do is think of a scenerio, like My 4 friends Sam Mark Lucy and John are all hanging out in my apartment with me when all of the sudden we see a broadcast on the tv and hear sirens and gun shots outside, what do you do? And you usually you pick a good story teller or something like that to tell you whats happening in the scenerio. Like lets say John says "ok, I'm gonna go effin run for my car in front of the apartment." and the leader or story teller has to tell you what happens, because you have to be specific with your decision. "ok, you get effin mauled by a horde of the undead, and you ran outside so fast that no one followed you. John your the undead, your out." or something along those lines. the teller pretty much decides your fate and your surroundings and the consequences.

And this is mainly fun to play with a bunch friends, all making there own decisions. I'm not sure what the name of the game is but, some how it was named 'What if Zombies...' but I think there could be a better name. Tell me if you have made up your own zombie game or something a bit like this one.
