Along with the lofty single player trailer (which you can see at the bottom of the page), 343 also released a detailed multiplayer trailer that breaks down the game modes. One of the most intriguing was the Spartan Ops co-op mode, which will progressively update with new content and missions to expand the Halo 4 storyline. More interesting still is the promise of integrating the Campaign, War Games multiplayer, and co-op modes into a single cohesive narrative. The more we see of Halo 4, the more interesting it's becoming. See the trailer for yourself below.
