You are an inventor and engineer in a small rural town. When news comes of a wave of zombies sweeping over the region, you immediately turn to a way to stop them. By creating the Zombie Attack Prevention and Extermination Machine (which, with your characteristic acumen for catchy names, becomes the ZAP ‘EM), you have enabled your town to weather even the most severe zombie invasion. Unfortunately, the ZAP’EM is rather expensive to run, and after building it you are pretty short on cash. You decide to turn your ingenuity into a money-making scheme. By renting out your zombie-slaying capabilities, you can become one of the richest and most respected people in town. That is, assuming you can kill all these zombies in the first place... At the beginning of the game you will place tiles representing homes, buildings, and terrain features-and, of course, zombies. As the zombies spawn and move around the board terrorizing (and killing) the inhabitants, you must chase them down and ZAP 'EM! If you are lucky, you may even earn some cash! Win the game by killing every zombie in town. You can also keep track of your high score (the amount of cash you have at the end of the game.) Other options include varying difficulty levels and a campaign system that allows you to string multiple games together.
