Sorry, but this is a terrible port from the arcade. There is nothing to recommend this game---absolutely nothing. Sadly, I was one of the unfortunate ones who bought this product. We had a users group where each month there was a drawing for "Dog of the Month". The 'winner' got the 'dog' that month. It seemed that this one was always recirculated because no one enjoyed it. What a shame because the premise of this shooter was good, and the arcade version was first rate. Keep truckin'.
