Whats the Story?

Wrapped up Modern Warfare on hardened the other night. Thoroughly enjoyable romp with the exception of the endlessly spawning enemies that had me gnashing my teeth on several of the stages. Oh, and don't even mention Mile High. Still, like the sucker I am, I will now go through it again on veteran to see if I can earn some extra points. Won't be for a while though as I have Assassin's Creed to work through first then Mass Effect and Blacksite after that. Oh Xbox joy!
