CityDefender (ste17001813)

You are a soldier in an apocalyptic world where zombies are rising in numbers as each vehicle accident occurs. No one knows why people are turning to zombies - all they can put it down to is a virus. All you know is you need to  protect your city and keep your people safe, as it is the most important thing right now. 

Not gory. Basically a kid's zombie game with squares chasing you.
