The ability to select your fire mode between semi-automatic, automatic, or three round burst. Or a two round burst in the case of the AN-94, which they should probably add. Basically the entire game is sound, just a new story, some added weapons, and maybe a few more diverse locals. The thing I really liked about the first COD was the fact that you played as Americans, British, and Russian characters. The first two have been done, but up to that point I had never played a game that let you play as the Russians in WWII, and I think the multiple sides were kind of ignored in COD4. Yes you have the Brits and the Americans, but they all end up using the same gear, and they play pretty much the same. Another side to it would be really interesting. If they keep with the same Middle East based idea, which they probably will since it's really the only modern war theater, maybe playing as a Pakistani, Afghani, or Iraqi soldier would be interesting. Basically though, they have what they're doing down, they just need to expand on it, make it a bit more varied, and hopefully make the single player longer.
