You know what's better than seeing the box art for a game you're looking forward to? Seeing an animated poster of a wide version of said box art. And would you credit it, here's one for Halo 5: Guardians now!
Continuing the well-established "Master Chief vs. Spartan Locke" theme, the most interesting element is the addition of two four-person fireteams to the mix, each led by one of the game's main characters.
Microsoft describes them as "new Spartans", implying some kind of character to them - I'd wager there's a fair chance we'll see Halo follow Call of Duty: Black Ops 3's example by including 4-player co-op in its campaign this time around.
Here's the art you can expect to find on your copy of the game come its release on 27th October.
