While we thoroughly enjoyed Halo 4, we've got to admit that we found the story a little bit overcomplicated. The whole thing sort of lacked focus and context, but that may be because 343 hid some of that context at the beginning of the second mission, "Requiem."

Scouring the wreckage after Chief hits the ground reveals not only heavy weapons like the sniper, fuel rod gun and SAW, but also several recordings that help to flesh out the story. On a bit of human ship, there's a recording made by Dr. Halsey regarding Cortana, and there are messages on no less than two Covenant ships—one explaining why the aliens are there, and the other simply repeating the name, "Diii…daaaact…" long before you ever actually meet the Didact in the game.
