All of the info Scotty has posted can easily be found in the Bungie Weekly Update. Although there is a chance that Scotty played some Halo 3, there is no chance it was the Beta. The only build that is playable right now is the Alpha. Which I'd like to add is supposed to only be available to Microsoft employees, and any talking about it would violate the confidentiality agreement that goes along with the Alpha. I know I have seen a person on my friends list that was playing "Pimps At Sea", which is the code name the alpha. They wouldn't say any thing about it, because they're not supposed to. If Scotty wants to mess up a good thing he has going, go ahead. Otherwise I'm calling shenanigans!
