Along with the revelation that Grifball will be making its way into Halo 4 multiplayer, a number of other exciting tidbits were revealed by 343 Industries at PAX. First up is a brand new ViDoc which takes a look behind the scenes of Halo 4 and at the emotional growth of John 117 himself. Of particular interest are the bits showing off Halo 4's motion capture setup, which appears to be borrowing a page from Naughty Dog's playbook and capturing the full physical performance of the game's actors.

Next up is a first look at the multiplayer map, Exile. Check out some screens below, featuring a verdant canyon setting and one guy being really mean with the flag.
