In my opinion, this is one of the best games out for Xbox. There are many good qualities about this game that make this game that make it better then other games. The sound effects are absolutely fantastic. I enjoy shooting the machine guns on the planes and just listening to the beautiful sound effects. The graphics like the sound effects are also every well made. They are no glitches or any other problems in the graphics. The gameplay is good all by itself. There is a good selection of airplanes to use. There is also a good amount of different enemies and bosses. Each boss has a different way that they can be defeated and you have to find out how to kill each boss. Everything about the gameplay is great, but the one thing it is missing is the ability to go co-op. The best thing about this game is the defiantly the storyline. The storyline is very good and it gets the gamer hooked into the game and keeps him/her hooked until the end of the game. The replay value is not that bad either. The ability to play this game on Xbox Live is awesome and entertaining. It really keeps you playing the game way past the story mode. Overall, this game is what can I say it is a must have for any gamer with an Xbox. I recommend that you go out and get this game right now in fact.
