While we can't directly embed 343 Industries' new video overview of Halo 4 Infinity multiplayer -- you'll need to head over to Halo Waypoint to catch it for now -- it's still worth a post. Particularly if you have not been following every bit of information about the game.
This video covers persistent upgrades, ordnance drops, the new scoring system, multiplayer modes, returning maps, Forge, Spartan Ops, and more. Even if some of the individual components of Infinity turn out to be a letdown, there's so much content packed in here that fans should have something to really latch on to. November is going to be a good month.
