I don't know if anyone has already brought this up or not but I just beat Halo 2 again only this time I payed a bit more attention since it's actually been a coule of years since I last played the campaingn all the way through but I was wondering at the end of Halo 2 they talk about the remaining instillations being ready for remote detination from the ark that Master chief was on and so far I've seen nobody mention anything about the ark in Halo 3. I've heard about foruner (sorry if I spelt that wrong) technology being discovered under the African sands and the story taking place with the covenate civil war but nothing about the ark or any of the other Halos. I'm just curious how a remote to basically wipe out life as we know it being only so far away from earth is going to play into the story?
