Undead Labs, developer of Class3, the code name for an upcoming zombie game on the XBox live network, has released an interactive zombie outbreak map using MapAList. There are pins on the map showing locations where a zombie outbreak has occurred.
Interestingly, the source of their data is voluntary submission of a form on their website, which is still open, so go ahead and add your location to the map. Class3 is a kind of proving ground for the development of Class4, which is going to be a massively multiplayer game set during the zombie apocalypse. Players in Class3 will provide feedback and statistics to further the development of Class4, which is slated to be a stand-alone game on various platforms. Concept art for the game is on Flickr.
