This is a teaser trailer for Halo Reach coming out in Fall, 2010. You should probably click the video so you can watch it in HD and get the full effect. It looks pretty bangin'. That's right, I said bangin'. YES I KNOW THAT'S NOT COOL. And neither is your face. Burn, no burn-backs!
UPDATE: Commentary-free video added after the jump for people that like to think their own thoughts. But you should still click-through to Youtube to watch it in high-def.
Thanks to Austin, who may or may not be the guy talking through the whole video (it totally is -- get him!).
