I think you have to make a new account.
You cannot turn off the blood but you can turn off the gore. If you turn off the gore it doesn't work in online play
I don't know how but you definitely can. Probably in the options menu.
sorry to say this but you can't, once you press ready you can't turn back.
I personally don't believe that cod black ops should be an 18. I have played it and i don't think it is actually bad enough to be classed as an 18. if you are concerned you can turn off the blood and gore at any point and if you believe it is too rude you can just turn down the volume. Multi player has reduced blood anyway so i think if you take all that into account it is not an 18.
No, you cannot turn off blood in CoD: MW2. Infiniity Ward made it there to make it look 'realistic.'
Well Actually you can't turn of Blood and Language that's why it's Rated M for Mature.
CoD black ops :)
Yes, go into the option menu and turn the graphic content off.
i would like to say cod black ops has better graphics. because there is actual blood in black ops. mw2 just has money fly out of the person when they die.
Rated M for blood gore and strong language
MW3 is after COD black ops.
you can its called muting ur tv
