I found a pretty good Halo webcomic floating around on DeviantArt. It's already complete since early November, 2012 and it's pretty faithful to the time frame it sets itself in (post-First Strike, Pre-Halo 2). Also, we get to see the Chief in Halo 1 era marine armour (and naturally, his face). There is a light touch on shipping in the comic, but for the most part, its base shenanigans, conspiracy (sorta), and action (near the end).
