This is my transcription for 'Requiem' from Halo 4 (the track that plays when you see the tall Forerunner structures as you leave the wreckage of 'Forward Unto Dawn'). The chords were difficult to figure out, so I did my best to stay accurate to the piece.
Craig Hardgrove, who is a planetary scientist working for JPL and also a Bungie fan from quite aways back, has written an article for Guardians of Destiny, talking about why he loves Halo, why he hates Call of Duty, and what he hopes to see in Destiny. (Hardgrove is also a fan of Bungie's Marathon series and even did some remakes of the game's music.)
GameSpot has posted the entirety of Bungie's GDC talk, given by Joe Staten and Christopher Barrett, about building Destiny's world and characters, over in their YouTube channel. Honestly, stuff like this-- showing the depth and breadth of thought that Bungie puts into making its worlds-- gets me a lot more excited about the game than trailers.
