Because Halo 4, that’s why.
Since Halo 4 details are pretty sparse right now I’m getting anxious so I decided to post this artwork that 343i released today. Let’s see just how much speculation we can do based on this one piece of artwork. What is the Chief doing? What’s all that broken crap behind him? Is he <spoilers!> busting out of the sleep pod thingy from the end of Halo 3? If so, why is he busting out instead of just waking up? Could this just be art and have no context whatsoever? Let us know what you think in the comments. Wild speculation is welcome and expected.
