COD 5 content filter

HI i was just wondering if the contennt filter in COD5 filters gore and language and if so in what modes?

I was also wondering if you could use the same serial for 2 pcs to play lan or coop?

i have heard that there is a blood and language filter, and it gets rid of all blood and language in the singleplayer, but multiplayer i'm not sure if there is blood. If language bothers you online, than you can unplug your headset and just play the game.

Hope this helps ;)
