City Zombies

Story I'm 15 and I'm a major! My parents are very rich and they have given me the most modern computer, a large number of games and the ability to sit at the PC indefinitely that I do not meet with the cruel world. So I was locked in my room in captivity and my servants brought me food and everything I need for a `normal` life. I spent in the virtual worlds of shooters most of my time. So it was all my adult life! One day my servants stopped to bring me food, answer the calls and then I left my room to eat… There was nobody in the house. All of them were infected with a virus that turned them into bloodthirsty zombies! There was the same situation on the street. The zombies had a keen sense of smell so it was no point in hiding. And I had to find weapons and confront them, beating their brainless heads off. But how long can I survive?.. Feature of game: Endless waves of zombies; Various of weapons; Leveling of weapons; Nice bonus for mass killings; Three different worlds; Steam Achievements.
