If you’ve ever wondered what variables would affect your town during a massive brain-hungry undead attack, look no further. The Class 3 Outbreak uses Google Maps to simulate the spread of the undead virus. Just wait for it to load, add your town’s population numbers, pick how many citizens are armed, how many police, and how good of a shot everyone is. Then, sit back and watch the magic unfold. It’s free, and it just might save your life. Or it could show you that you don’t have a chance.
