I originally gave this game a 6, but gave it an extra point for personality. It's not technically great, has bugs, at times too hard, at others too easy, and is very very repetitive. However, I moderately enjoyed it. The cover system works well. There are some funny moments. Trophies are pretty easy to earn.
I liked the lightheartedness feeling of the game. With all these incredibly serious titles that really pressure you to do specific tasks and put you down for not accomplishing them, it was fun to...well....have fun. Check it out.
I rented this game with huge expectations. Thinking it would be a fun hilarious game as fun as Uncharted, man was I wrong. I mean, it's funny. Matt makes funny comments, weapon selection is really good, good voice talent, and just okay graphics. But this game can not, and never should compare to Uncharted: Drakes Fortune, which I think is the greatest PS3 game out there! I recommend that one instead of this one. But if you have a weekend of boredom, pick it up and you'll enjoy it until you realize that it's kind've lame.
Pros: Funny comments, good voice talent, graphics are pretty good, awesome weapon assortment, and aiming in and out of cover works really well.
Cons: Weird storyline, bad level design, horrible A.I. and camera view is stupid.
I would recommend this game for a weekend of fun, and then not much else, I give it a 7.5, so and 8 is decent. Go and play Uncharted right now and you will have the time of your life, and when you beat that, then play this game for a few days.
