Halo 3 Announced For Xbox 360. Due In 2007As the conference was about to conclude, Bill Gates reminded Peter Moore that there was one more thing left to show. This was of course a trailer for Halo 3, billed as the third and final chapter in the Halo trilogy. The trailer began slowly with the camera moving backwards. Cortana is seen in flashes, and is heard saying "I am your shield and I am your sword" As the camera continues to move back the unmistakable figure of Master Chief walks into view. Then, in a distorted voice, Cortana says "I know you. Your past. Your future." After a slow start Covenant Banshees and battleships begin to appear in the sky and a beam of light begins to build from an opening in the ground, blinding the camera. Cortana then adds, "This is the way the world ends," with the words "Finish the fight in 2007" then appearing on screen. Whilst not the gameplay footage wed hoped for, the trailer did look mighty fine, but that was to be expected. Now we know for sure that the game is on the way, we await more details on the 2007 release date.
