This game has most definitely earned my praise of being the greatest coop game I have ever played. This game will bring a new concept to all that you have ever experienced with multiplayer first person shooters.
The graphics are, as would be expected from a Playstation 3 anyway, amazing. Dazzling detail with everything in high definition, wonderous character detail, and flawless firearm detail. This game has really nailed the potential of modern graphic design. Secondly, the gameplay is absolutely fluid. All the melee attacks and continuing on through the basic movement are absolutely amazing when it comes to the fluid motion of each action.
The storyline itself is also a really wonderfully designed piece of work. It will continually make you guess what will happen, and the gameplay is changing throughout the story just enough that it never seems like you are doing the same thing over and over.
I did, unfortunately, have to rank this game only four out of the five possible stars due to a repetition when you are upgrading weapons to play again. In this game, it is designed to keep funds and weapon upgrades and allow you to play through the game again to earn further upgrades. Unfortunately, this means that you will be playing through the story eight or nine times in order to have a complete arsenal. After having beated the game for the first time, it does give you all the primary weapons; however, any secondary weapons or upgrades will cost you.
Other than a mild repetition of gameplay, this game is flawless. I easily rank this game as a 9 out of 10 and also label it the best cooperative game I have played.
