I heard from somewhere that Bungie said there were no f bombs

Does it have any bad language in it?

I just played Halo for the first time and I don't think it is really that bad. There is a little blood, but thats about the only bad thing I saw in it. I have Call of Duty 2 and it has a lot more blood and language in it, and it got a teen rating. What do you guys think?
