Btw, if anyone wants to actually understand the story before playing Halo 4, then do this:

Read Fall of Reach and The Flood, play Halo 1,Read First Strike, play Halo 2 and Halo 3, read Ghosts of Onyx, Glasslands, The Thursday War, and then finally you can start Halo 4. Now you'll actually be able to understand what all their cryptic story bullshit is about (Infinity, Didact, Requiem, and most importantly, Jul 'Mdama).
