Talk:Halo 3 announcement trailer

Could it be
when it says
 * The enormous hole in the swirling clouds above the middle of the structure in the crater is, according to Bungie, caused by strong, unseen forces from the structure itself.

could the strong unseen forces be the forunners them selfs and this is why they never used the shield worlds or if not could the unseen forse be a type of enemy for halo 3. User:Kami-Sama

This trailer is based towards the end of the game
My theory is, is that out of desperation Cortana somehow found a way to activate the Ark. She activated it because Gravemind now got the information he wanted from her and is on his way to earth. But are good friends, doctor halsey and the spartan III's find a way to Earth. Earth is really a shield world. Halsey making a connection between the forerunner symbols looking like aztec sends the chief to an old aztec temple where he finds a device that will allow him and the others to get inside the sheild. Now either they'll find a way to zap all the humans to the core or they find forerunner technology and re-create the human species. Long i know and filled with holes but that's how i think it ends.-guy who likes elites.
