Android Zombie Outbreak, just in time for your upgrade to an Evo 4g.

Pixelated of course, this neat little active wallpaper for your Android 2.1+ phone will keep you guessing just how much longer you have until you, the lonely green pixel gets devoured by a nasty little red one.

Able to set your desired population numbers (zombies, people, defenders) and view stats in real time, this neat little $1 outbreak will have you staring at your wallpaper for hours trying out hundreds of different configurations to find out just how you might survive the next zombie apocalypse yourself. Of course if things don't turn out how you like them, you can just destroy the entire population by dropping a nuclear bomb, or an icon.
