I always wanted to own this game but I kept seeing it for $40, used, so I just avoided it. I finally saw it for $15 and had to buy it. It's a short game, only 7 levels, but there is some replay value. You can choose to play each level on its own, fight just the bosses, or do the regular mode. There's artwork to unlock as well and it's some pretty good material to look at too. I haven't passed this on Very Hard yet, and don't think I well, but it sure if fun to just blow the shit out of everything with a Level 8 spread gun!
