When you think of this game, think of a B movie, because thats what this is. It's based on a B movie, with a cheesy story line, but that' what makes it good and very funny you just keep laughing at the 2 characters lines.
This an arcade style zombie shoot-um up and you don't have to worry about moving your chacter around because the computer does that for you. This is the kind of game you can go on for a short game without having to spend hours trying to find a place to save or stop. I also find it good to get my frustratings out on if I have a bad day, especally now Ive unlooked better weapons. You always have something to aim for on this game, from high scores to more money or just pointless shooting. You also have a few side games which are very good as well.
Remember treet like a B movie or game to take your temper out on by pointless shooting of zombies, and you will really enjoy this game.
