[url=http://www.youtube.com/watch?v=QULEcokHPQc]I'll assume we've all seen the ViDoc, but just in case...[/url] This thread is for speculation of the Campaign. A brief outline of the things that were "new" in the above linked video is provided by yours truly below (if I've missed anything please say so!) - 1:39 in the video - one of the narrative designers, Lindsay Lockhart, says this: "..Chief is a guardian. Cortana is his guardian. The Forerunners were the guardians of their own Universe, and [b]they[/b] might have to make a decision that not everyone is going to agree with and some people are going to condemn". "They" is not specified (is it Chief/Cortana, or the Forerunners?) - 2:25 in the video - Jen Taylor voice acting as either Cortana or Halsey (most likely Cortana in my opinion), she says "I'm not doing this for mankind". What is "this"? - 3:19 in the video - a shot of Infinity and a powerful fleet surrounding it, consisting of Marathon-class cruisers. - 3:33 in the video - a shot of two Phantoms being annihilated? By a sphere in the background similar to the one we saw in the E3 demo. - 5:10 in the video - a shot of (presumably) Captain Del Rio of the UNSC [i]Infinity[/i]; confrontational with Chief. The big thing here is, Chief clearly turns to face Del Rio with a hint of threat; it looks like Chief is confronting a superior back, not something we're used to with John's usually ice cool nature. - 7:14 in the video - a good section of video showing Chief and Cortana talking about her mortality. Chief mentions getting back to Earth to get her to Halsey, but we know Halsey is locked up near Installation 03 on the top secret ONI research station [i]Ivanoff[/i]. - 7:43 in the video - Cortana struggling with a flood of warning and error signs. - 8:11 in the video - Cortana apologises for her outburst, flickering red, as Chief, Del Rio and (presumably) Lasky look stunned. - 8:21 in the video - Cortana recognises a Forerunner symbol for Reclaimer (tie-in with Mendicant Bias's fragment on The Ark sending Chief here?) - 10:08 in the video - Chief walking out on Del Rio, his superior. O.o - 10:13 in the video - Chief jumping off a Ghost like a badass. Sorry, had to include it. - 10:18 in the video - is that Halsey?! She lookin' old. Does this mean Chief visits her at the Ivanoff research station? - 10:33 in the video - eerie moment as Cortana says "Don't make a girl a promise you know you can't keep". Notice the contrast with her Halo 2 line "Don't make a girl a promise if you know you can't keep it". This time, she seems sure that Chief will be unable to hold whatever his promise was. Ok that's all. Speculation 1: I think there's a definite link between this decision that Chief/Cortana will make that people won't like, the scene where Del Rio was angry with Chief, and the Cortana line "I'm not doing this for mankind". I'm not sure what but I'm certain these points link up. Will add more speculation as I think, please do the same!
