First off let me say that I haven't completed the game yet so there could still be more for me to experience.
My first impression of the game was that it is a combination of Brothers in Arms meets Medal of Honor meets XIII. By this I mean that it's a war game with realistic weaponry but it has a cartoony exterior which I think takes away from the game a little. Also, the story description on every site is rather lacking and in fact, inaccurate when you start to play the game. When you start playing the game you are told a different story which again, is in very little detail which is a bit annoying.
Interesting quirks to the game are the "special powers" that you have which range from being able to stop bullets and time and other similar Max Payne abilities. These are in fact a nice addition to the game and are combined with gaining experience in order to further improve your skills.
Overall it's a reasonable game and at this price you can't complain. The gameplay is reasonable although a bit wooden from time to time and the character voice overs and animations leave a lot to be desired. Generally however, quite entertaining!
