Using the Yes it offends me option was a good idea.  It will tone it down but since I haven't played on that option I don't know for sure if you have anything more to worry about.  I know on the standard play there are quite a few F bombs.  I don't think that there was anything in it that I'd classify as gore particularly.  Lot of people dieing for sure and the end of the last mission would probably be the most disturbing part.  Hopefully, someone whose been through the Campaign on the "it offends me" setting can be more helpful.  In the meantime, welcome to the game.

Well all the mission have cuss words in them for the most part i would play with the sound low since you have kids just make sure your kids arent around abd if they are keep the sound off or play with headphones

A little word of advice. Stick with the wii mote and nunchuck. DO NOT BUY A ZAPPER. Its a piece of plastic. Worthless and stupid. A nintendo gimmick to up their sales.

Also, if strong language is of concern,i strongly suggest turning off voice chat in multiplayer. What's worst than a voice actor dropping the f bomb? A 12 year old child dropping the f bomb and saying he has slept with your mother while squeaking many other sexual things his 12 year old mind should not know about.

I dunno...there isn't really tons of F-bombs in MW campaigns..Black Ops destroyed Europe with the amount of F-bombs f**kin dropped. Treyarch doesnt censor their games- they're all out with the language. You dont have to worry about language in MW3. As for gore...well, there's none. But there is people dying pretty disturbing deaths, if thats bad enough.

IW is pretty clean with their language and gore. But to be honest, if i was trying to kill a big name terrorist on the top of a hotel- in which this terrorist is responsible for the lost of COUNTLESS lives -including my best friend- i'd cuss like mad.
