Fun, but hard
I would definitley recommend this game to anyone who likes zombies, but man is it hard to play. You would think that with only four levels, it would not be much, but boy was I wrong! There are just hordes after hordes after hordes of monsters coming at you! Don't even think for a moment that a $3,000 attack will ensure victory. It is definitley complicated and it was weird to see that one giant zombie attack you. The graphics were really good and the gameplay was pretty straightfoward.
