Ok i played the game and it is my thoughts :

The massacre scene playing it, had no impact and no immersion at all on me :
level , characters looked like in a video game, not immersive !
i think that seeing the video before , put away the discover effect (when you don't know what will happen) !

Even screams , where very standard screams played by actors!
You'll never earn real screams mixed with crys where you feel really bad or they (or they need to go to a real battlefield)!

Sure it's a game it's so totally irrealistic : shooting all special forces so easily :
Speacial forces have Snipers and Commandos that you won't put down like that

Another point : they should avoid putting so much videos, caus it you loose all discover effect about half of the game.

I've done some levels (not finished) :
The levels are short sometimes, lot of guerilla and goals in a same zone ! No connexion between levels !


Personnaly for me :
It's another war FPS GAME ! very far far far away from what you feel when you look at a documentary with people crying the dead of a member !

But Big game : very good sounds compared to MW1 , very smooth, better detailled levels and characters. Big game indeed.
And Multiplayer is fun as hell
