The maps, though simple, are huge and have death lurking around every corner. I was happy to see a good variety in the types of zombies that were coming after you. I am sure the full version will have more, but there were normal meandering zombies, poison gas-filled ones, and athletic, fast zombies, just to name a few.
The entire look of the game is simple and streamlined, as are the controls. This just leaves you to shooting, sawing, and burning your way out of the city. One of the weapons is a Molotov cocktail that you target and lob. This took a little finesse to master, but was very fun to watch. The reason I mention this is that it showed more depth to the game's weapons than just shooting pellet looking bullets towards zombies and hitting them enough times to kill them. You were capable of sometimes scoring heads shots, which dropped the zombies faster. But, I noticed that this didn't keep them from reanimating if you decide to hang around and sing songs together.
