Bungie recently let a few press people into their studios to show off the Halo 3 single player campaign, and Sympatico just published a very in depth article about what they were able to get their hands on. The number of reveals in this article are quite impressive. Our favorites?
The Scarab Conflict (where you take down an actual Scarab in one of twelve different ways), a small part of the 4th level "The Storm", has more enemies and allies involved in it that the entire first mission of Halo 1.
And gay Brutes. Yes, we're serious. Hot Brute on Brute action.
Read it all on Smypatico, and try to keep your tongue in your mouth.
Update: Fixed the link. And figured out how to spell tongue.
