Ok, here's the drill. Your sitting at home, watching Sponge Bob, when suddenly, a news bulletin cuts into your program. It tells you about a pandemic going on, and to stay inside while the situation is being handled. The visual cuts out, and you hear a loud scream, and some other weird noises before Sponge Bob comes back on. You go to your window, and look outside. Everything appears to be normal, when a bloody body smacks your window, trying to get in.
The rules of all standard RPG's apply here, accept there are millions of zombies, so I'm allowing most auto hits on them. No catastrophic explosions that wipe huge numbers out. Also, these zombies are acquiring knowledge in fighting forms. They will soon know how to use weapons, and other strategies to combat humans. They can bite most anyone, and people immune to most diseases will not be affected as much from the zombie bites. Also, zombies can infect you by getting bodily fluids into you. These zombies are super powered in all normal functions, and once they bite a super human, they will eventually gain those powers. They can only get your powers through biting. Also, once bitten, you only have about an hour before you zombify.
Goal: Try to find a cure to stop the spread of infection. There is also a rumor that the souls of the people are being held somewhere. If you can free those souls, it might reverse the affects. Good luck!
