Roughly 1/3 casualties in war are soldiers and the rest are civilian. Such is the world I'm afraid and its not like you're not able to kill innocents and civilians in other games as well, shooting doctors in the head so the skull fragments fly all over in Half-Life, random beat downs in GTA as mentioned and countless other games feature this possibility.
I haven't really seen a game with a level where the objective is to actually kill innocents though.

PS: I was truly shocked to learn that the evildoers were Russian, very original...

I already beat it and the game give you the option to skip this level and turn off gore if you choose

they are not russians, YOU are russian.

he killed you to blame russia for doing that.

he told you to not talk russian at the start to make you feel like he is defending russia  but he betrayed you and got away with it, now america will blame russia because they found your body and you are russian.

now your dead is the message he is trying to send. got me?

no offense, but why are you guys so lame?you sound like sucker moms.it's just a freakin game.

Shooting unarmed civilians.

MW2 IS FUCKING CASUAL!

no offense but not everyone is a spartan.

Actually you play as a CIA agent infiltrating the Russians. So it's US & Russia vs Russian civilians? WTF?

wow, looks like a really good game. I like the idea of putting you in the shoes of the villian so you understand better why you are fighting. This happens all the time in movies and it makes even more sense in games.

No offense, but why are you so much lammer?

Your discussing if a video game for the Xbox 360 video game console will outsell a proluge of a series of high selling

games on a differnt system.

That sounds way more lamer then this thread.
