I have to praise you for having decent graphics. At the same time, I just didn't think this held up on numerous levels. I didn't like it how it was just the same place over and over. A lot of the effects even looked a bit too cartoonish, even if it was overall good. I appreciate how popular this has become. I always try to acknowledge that, even in something I don't like.
The music is fairly decent. I've never cared much for the Call Of Duty games in the first place. I've become familiar with them due to how popular they are. At least it wasn't too hard for me. It was a good idea to have modes.
