The game to get this year!!
First to answer your question alaneo2012, yes this game will work for your European 360, if you get a game that says No Region Protection which is both the US addition and the Asian in this case.

First off I have to say that this game is absolutely worth every bit of money. This game is so much fun, from the Campaign to the Multiplayer and the new Special Ops. If you're thinking about getting this game don't think, just do. MW2 is basically CoD4 just enhanced with steroids. It's almost perfected for those FPS lovers. The Multiplayer is great, the maps are significantly larger and much much more fun with many more weapon attachments to unlock. If you don't have this game already, just get it already and stop reading reviews.

HEY ALANEO 2012
HEY MAN BUY THE NO REGION PROTECTIO GAMES AND U WILL BE ABLE TO PLAY ANY GAME U WANT TO

Call of Duty: Modern Warfare 2
GET THIS GAME!

If you love this genre then MW2 is the game for you. Multiplayer is the best I have played and this game will become a classic! Best game of 2009!

Well worth the wait
With the first Modern Warfare game so good, the sequel had large shoes to fill. However it delivers a great game, with a very compelling story, and a fantastic online gaming experience. The game could have been a bit longer, but I imagine the online game will continue to eat up all my free time.

Excellent game
Modern Warfare 2, though having one of the shortest Single-Player campaigns in the series, is also one of the most exhilarating and terrific titles to date. I had very high hopes from the game and it truly gave me more than I asked for. Although the Single-Player experience may not give you too many incentives to play through again, the Special Ops and Multi-Player modes will keep you hooked for a long time.
