A bomb went off, the radiation did the rest, and now the whole town wants a piece of you. You are a kid on a watchtower with a rifle and a wooden fence, and that is all you get. Drag to aim, tap to shoot, keep the barricade standing. Collect the coins they drop, plant mines where they walk, and save up for the shotgun. Six stages, six waves each, and a boss waiting at the end of every one. The airport is where it gets nasty.
