What other Halo characters do you think will make an appearance in the game? Some nice cut scenes with the doc and maybe the other spartans from the books would be cool.

I can't see what she would do in the battlefield, isn't she just a regular scientist ? Not some gordon freeman in a HEV suit.

Just in the cutscenes.

Perhaps, perhaps not, can't really imagine why she we would be nearby, wouldnt' she be engaged in research of some kind ? I

Maybe in a cutscene. I can imagine a mission where you might have to capture a case of energy shields or something, and afterwards.You see her getting the news of the succsess. Or, when we get Spartans, I could imagine the captain (us?) getting breifed.

I don't think so.  It would be almost like showing Johns face. Some of these characters need to stay on a text basis.  It only takes one line to kill a character and only one look at a face you wouln't have expected to be attached to that person.

Well if im not mistaken Hasley was 20-30 on FoR. The war had been going on for roughly 30 years. And this game takes place at the very begining meanging Hasley Is a baby or not born yet. And keyes would probably be pretty damned young too. And therefore not Cortana because Cortana was based from Hasley

The Spartans were abducted in 2517 when they were all around 6.

First contact with the covenant was in 2525 when the Spartans were 14.

In 2552 (Halo 1 & 2), the Master Chief is approximately 41 years old.

Doctor Halsey should be at least 20 years older than the Spartans.

Cortana is supposed to be a carbon copy (in both appearence and personality)  of the good doctor, while she was young.
