I almost completed the campaign when essentially everybody on my friends list wanted to play multiplayer. The game is what to be expected, a beefed up CoD4 that expands on what they "perfected" in the first game.
One thing I must say is they really did a better job on the maps this time around. In the first MW the maps were small and if they were big they often had many dead ends. The majority of maps I played last night you could essentially go 360 degrees around the whole map and the maps were on a much bigger scale.
It's one of the best first person shooters I've ever played, but not the best game I ever played. It is worth a pick up of you're into a short 4-5 hour campaign experience. If you're into online gaming on consoles, you should probably pick this game up right now or you will be playing your games alone for awhile.
