I don’t know what the developer was thinking when he created this game, but he did a good job to say the least. The funny thing is the game has become an addiction, for many people. Because it is entertaining, and a little fascinating, you will almost always play this game after school or work. In this game, you are a zombie – a dangerous zombie – and that’s pretty much a tough spot. But you are a highly motivated zombie. You have to spread infection in as many cities as you can, whether large or small. What’s more is that you can upgrade your disease as you continue the game.
