Last week at Microsoft's Spring Showcase, I and a whole bunch of other reporters got our first look at this fall's Halo 4. The fourth proper entry in the franchise (not counting ODST and Reach) will be released this fall, and will feature longtime series star Master Chief in an all-new adventure.
Halo 4 will be the first Halo game not made by Bungie, who created the series ten years ago. Instead, the game is being created by 343 Industries. At the event, 343's Frank O'Connor and Kiki Wolfkill showed us the above video, and shared some information about the coming game. Vague information, but information nonetheless.
The first thing they showed us was Master Chief himself, whose armor has been slightly redesigned for the new game. (If you recall, the armor he was wearing in the game's E3 debut last year wasn't his final, official look.) We'd already seen an action figure depicting Chief's new look, and this screenshot confirms his lighter, more flexible new armor.
