E3 2014 Destiny Trailer "New Beginnings"
Bungie put out a new Destiny trailer for E3 2014 that lays out the game's premise in a pretty straightforward way and also shows off a bit of gameplay.
UPDATE: The audio in this version is messed up. A replacement is uploading, and when it's done, I'll replace the embedded version here with the new one.
UPDATE 2: This version should have the fixed commentary audio.
