basically wat da subject says...cant explain any better than that.  im hoping 2 get some good info, and then maybe buy it this week.

Sorry, what?

It has co-op, for one. If that's what you were asking.

25 kill streak and you can drop a nuke for insta-win.

As if the MW Helicopter, WaW Dogs and KZ2 bots weren't deadly enough...

ya, thats it.... err not.

 And I have played for 10 hours or so online and have not seen a nuke they are really rare. There is tons more about 2x as many total weapons, 5x as many challenges, 10 attachments for all ARs, 8 for SMG, 8 for LMG and 6 for Sniper Rifles. Maps are MUCH better than MWs. Co-op mode. A ton of collectable in MP (that u dont lose when you Prestige)

If you enjoyed MW then I highly suggest you upgrade. Yea, it is not an entirely new experiance. But it is like a windows upgrade from 98 to XP (WaW was ME, lol) there is just so much more to the game.

everything on mw... is much better on mw2

The guy that said there is so much more in MW2 is right. However he forgot to mention the fact that IW clearly spent all their time making crap to add instead of trying to perfect and balance out and make sense of what it was that they did add.

It costs 10 pounds more :D
