Across the street from PAX Prime this year is a floor completely dedicated to everything and anything Halo. HaloFest basically is a musuem containing cases full of history, the WETA designed Warthog and even an entire section where people can play with Halo MegaBlocks.
Of course, Halo: Anniversary is playable during this weekend's festivities and players can get in on the new multiplayer maps or the newly revealed Firefight content. And hey, if you happened to be around last night, you could have gotten a piece of this insanely designed Halo cake. It looked awesome and so gross!
