Cortana Quotes from halo 3

I absolutely believe you in the fact that cortana said chief leave me. She is probably delarious. In the halo 3 announcement trailer, you could even hear her scream right before her first appearence...--Halo3


When did Cortana say "leave me"?. She said something more like this: MC" Dont worry I'll get you" Cortana "Dont make a girl a promise you cant keep" --Will 16:07, 6 January 2007 (UTC)

You guys... During the last portion of the level High Charity one of the lines Cortana says while she's watching you fend off the flood attack is 'Chief, Leave me.' Which is what she says in this. She isn't actually there, he was knocked unconscious and is remembering her say that. CaptainAdamGraves 23:34, 8 January 2007 (UTC)

Well, I agree with that, but Bungie is doing an awful job if they were trying to do this effect to make us feel that Cortana's word is haunting the Chief--Master Chief Petty Officer 05:07, 9 January 2007 (UTC)

Someone should add that she is based off of the mind of Dr. Hasley herself(although she isnt dead yet.) it states it in The Fall of REACH somewhere. 72.144.137.236 01:07, 10 January 2007 (UTC)

Halo3 Starry Night

We are talking about the Halo 3 starry night trailer that came on the espn football game. If you can stream the commercial T.V ad. Turn up the volume to the lowdest you can get it and listen very carefully.--Halo3Halo3

You didn't realize it was actually talking about Halo 3, didn't you, when you first saw the two kids you are not really thinking things relating the Halo 3?

Rampant

If you listened to the ILoveBees series, the AI (i forget her name) says that after a certain amount of time (of gathering information like Smart AIs do) they start to become to complex and go rampant/crazy. at the rate that this AI was gathering all of human intellegence it would have become rampant after 7 years. Cortana however was in the core of halo, as well as human starships and REACH, so that means she has collected much more data than The ILoveBees AI. In Halo: The First Strike Dr. Halsey Tries to take some of the data Cortana gathered in order to keep her from rampency, however in halo 2 she not only goes back to a halo but she also goes to high charity. she has probably gone rampant from being far to complex (full of data), making her question her own programming (like she did in he conversation with another AI (I dont remember where)) and feels she should help Gravemind (a very Pursuasive being if you remember). -72.144.137.236 01:05, 10 January 2007 (UTC)
