Don't be tempted Nekro!!!!!
Anyone had a look at this?

It's a zombie outbreak simulator which uses GOOGLE EARTH!!!! You can change the amount of zombies/citizens/police, the speed of infection and the zombies, and lots of other things - it's really quite good.
I believe that they are also trying to make one using the entire earth rather than just one part! How cool would that be!!!!!!!
