Plants vs. Zombies: City Defender

Plants vs Zombies: City Defender is a spin-off version of Plants vs Zombies. It is similar to Adventures in one aspect: it involves a city. Unlike Adventures, you are an anti-zombie army taking over zombie-filled territory. Unlike regular Plants vs Zombies, there are no truly defined "areas", just plots of land to take over. Area difficulty is measured in Brains. It scales from one Brain, "Brainless", to five Brains, "Impossibrain". The art style for battle is that of the original Plants vs Zombies. Most plants and zombies from previous games make a return.
