I've played plenty of shooter games like this before but this is, hands-down, my favorite! It's a very clean, straight forward design and I've spent hours on it! The best part is that the kids love it, as well! It really helps pass the time in waiting rooms and in traffic. As any parent will tell you, silence in the backseat is golden! As for me, nothing beats the pure satisfaction of knocking a big chunk of balls down.
