Of all the enhancements to the Halo franchise coming our way in Halo 4, the one we're most excited about, once you get past the fact that Cortana will be a life sized A.I./hologram with a centerfold body, has to be the Spartan Ops feature.
Yes you'll be shooting aliens and there will be new guns and all of that Halo sci-fi but at this point in the franchise's life (this will be Xbox game #6 after all) it's got to be all about new franchise features. This time around it's Spartan Ops --free, 4 player co-op episodic content-- available the week Halo 4 launches. This could be one of the biggest developments in gaming if it works. If a parallel storyline involving characters and locations developed in a pre-release web series (starting this fall) can be fully playable and updated every week with 4-5 hours of playable missions works this time with Halo 4, other developers will be compelled to offer added value as well right? Right.
Have a listen as the game's Franchise Director and his charming accent take you through some details of Halo 4.
