Kill all the zombies to beat each level. Protect your civilians and don't let the zombies get them otherwise they die and are turned into zombies. If all civilians die you must restart the level. Be careful not to hurt the civilians with friendly fire! Collect cash and use to purchase upgrades in the upgrade store. Very well done overhead shooter. The only funny thing about the game is some civilians are lemmings...?
Instructions: Use arrow keys or WASD to walk. Use the mouse to aim and shoot. 1-4 to select weapons
