It's almost exactly the same, but there have been some changes over the years. I've definitely received my money's worth of entertainment for what I paid. I think my favorite change in MW3 is that you can select exactly which one of your kill streaks to activate (5,6,7) instead of having to use them in reverse order of when you acquired them. I do miss the grenade launcher being awesome, it just made people so mad. The new Drop Zone game type is pretty much the best thing ever. So much fun! The single player was alright, standard fare at this point. I mean it's basically the end of the story that started with CoD4, and I'm alright with that.
