Fun..But can use some work...
Ok, now the reasons for the lower score.... First, has to be the annoying enemy UI. I am really surprised that the GameSpot video review did not focus on this short-coming. Enemy mafia guys will always spot you, even when hiding behind a tree. Always snipe at you, even though they are so far away from you that they would never be able to actually see you thru the bushes and trees. But most disturbing, is that the people will run straight for you, and thus, let you mow them down nice and easy. I suggest choosing the shotgun, or machine gun for fighting in a building, because they will just run at you. I must have killed close to 15 guys on the stairwell. I simple stood a little lower on the stairs, and they just kept running at me. Secondly, the game is a little short. You will be asking yourself after the last battle; "Is that it????". I think it was a little too short. Howvever, the game did cost less, so it is not a real problem. Overall, the game hints at what the 360 can do graphically. I have to disagree with the reviewers that say that it really pushes the new system. I think that it merely "meets" the lower end of what the 360 can do.
I think that it is still a good game to buy. However, since it is such a short game, it is also good for renting. If you have some people come over, you can rent the game and finish it in the same day.
