Link too late its already over guys.
But holy cow that game looked PHENOMINAL!!!!!!!!!! They showed Reach the planet and its simply beautiful to look at. So many little details including ambient wildlife that will just walk past you as your creeping through the undergrowth looking for Covenant. They showed large birdlike Moa that run similar to ostritches.
Also a possible spoiler....
it appears that the character you play as Noble 6 may die. At the beginning of the game it showed a video of Reach blasted and glassed, its surface hot as a volcano.....and Noble 6's helmet lying on the ground with a bullet hole through the visor.
