Excited? About DLC? I'd normally rather throw myself under a bus, seeing as 90% of the stuff is usually over-priced fluff, but 343 look to be putting a ton of effort into Halo 4's fancy Spartan Ops game mode.
An episodic series of co-op and multiplayer experiences, I knew they'd have some sort of narrative attached to them, but damn, didn't know they'd even spent money making more of those gorgeous Halo 4 cinematic sequences for them as well.
I missed the first episode, but the second should be out later today.
