It gets better!
From what I have been reading, its sounds like we will be able to play HALO Anniversary at the event.
How sweet is that?
it's going to be a awesome weekend. On Microsoft's web site they talk about HALO fest, and they said we get to play the campaign and the mutiplayer there it keeps looking better and better. Defiantly the year for HALO fans at PAX. Since we are going to be in armor I figure they will hook us up with some cool swag hopefully.
