The world has been taken over by a virus. Not a virus, but a huge danger. Zombie apocalypse. Not everyone managed to stay alive. But fate did not let you down.

So. Now we know that you are alive. But are the others alive? Let's find out. You climb onto the roof of the 4th house, it is completely clean, and is your refuge camp. There on the roof you see four guys.

Bill, Tom, Gustav, Georg. Georg is 18, Gustav is 17, Tom and Bill are 16. You are also 16 by the way.

The choice is yours, call them or refuse the opportunity.
