I've had this game for the past two days, yay Bolivian black market! Unfortunately the game is pretty mediocre.
I can't really put my finder on it but this game lacks heart. There is no story! You get a lot of fast camera cuts and fucking numbers popping up everywhere during flashbacks. The games cutscenes just feels very fast paced without reasons.
You have your typical CoD hollywood type scenes like riding a motorcycle and escaping a Russian POW Camp, or defending a huge onslaught of vietnamese soldiers in Khe Sang. But like I said you don't know why you're doing these things.
The framerates are spectacular as the previous game. Solid 60fps ALWAYS. No gripes there. The character models look even better than before.The guns 'feel' light. I guess this is for most CoD games, but I prefer it when bullets are heavy. One hit or two and the enemies are down, and likewise for yourself. Like FEAR. But hey, not every gamer has the same tastes on this particular area. Your weapons in this game almost always start out with 900 bullets, giving you quite the message to just spray and pray. :/
All in all I'd recommend a rental at best and then judge the game for yourself.
tl;dr: Very good technical accomplishments, but lacks heart of previous games.
