Played it the first time I played the game, currently working on Hardened mode, played it then too. Once I go to Veteran, Ill play it there too. And it's called "No Russian".
Honestly, it's really stupid to say it shouldn't have been in the game, or, it's horrible to do. what's the difference between killing a bunch of people in an airport, than killing a bunch of militias in Rio later on in the game? Occupation? Not a single person will play that level and say "Wow, now I know how to carry out a terrorist attack". Pointless controversy started by useless media. Yet again. How pointless? Apparently, Mass Effect 1 doubles as a full fledged sex game according to many main-stream media outlets, yet, if you actually play the game, it's only one scene, and barely anything is shown.
I'm really getting sick of people taking a game, and blowing a small part of it WAY out of proportion and then thinking, "Well hey, if this is in the game then the rest of it must be just as horrifying." Well, if you think about it, yeah. War is horrifying. Don't like it? Put down the controller.
