Everyone aboard the Halo 4 hype train, helmed by the Master Chief himself. 343 Industries have released a trailer which showcases some motion based concept art for the game, giving us a glimpse at strange alien worlds, possible new enemies, and much more.
There's not much here to go on, but any Halo fan will at least find the video a little bit titillating. We've only got a year to wait till Halo 4 is released on the Xbox 360.
