The game is a lot of fun. I've only been playing it for a few days so I really can't offer much of a review. If you want a real review, check
this one out at
GameSpot (my favorite games review site). Really, I just wanted to enter my one gripe with the game. It doesn't offer a multiplayer co-operative mode where you can work through the single player missions. That's really limiting because most of my friends don't own Xboxes and don't have the experience using the controller that I do. That means in all the shooter multiplayer games where it's me vs. them I win all the time and they're super frustrated b/c they never get a chance to learn. Another annoyance - when you ARE playing multiplayer in a deathmatch or team deathmatch, the machine doesn't spawn any AI bad guys. It's just me vs my buddy. That makes the game boring.
However, the single player and the Xbox Live games with 8 people in the game are fun. More players in the games are required. The original Xbox sported games which could host up to 32 players in a single online match. What's up with the ultra-powerful Xbox chaining us down to 8?
