This simulates a zombie infestation in a city. You can control some factors such as whether zombies can break throuh walls, randomly drop nukes on zombie infested areas, and increase/decrease population and military (controls for these are on the right side) http://www.sothisisacomic.com/Zombie/zomb3.html I like to wait until there are only about 200 humans left, then start dropping nukes, and seeing if they can survive :lol: there are also some mods half way down the page. One of them lets you choose where to drop bombs ^_^ I only wish that there was a screensaver version of this...
At school we had a game along those lines, but it was foxeses and rabbits but almost exactly the same!
