The folks at Bungie are celebrating 20 years of doing whatever it is Bungie does... make games, I think! Halo, Marathon, mystery projects for Activision and stuff. They've created a nearly one-hour long documentary about themselves, promising never-before-seen material.
They're calling it "O Brave New World". Official description: "...a feast of infotainment sure to satisfy even the most ravenous fans — a behind the scenes look at the turning points, the moments that made us Bungie. It's full of rare and never before seen footage, reflections from our best friends and biggest fans, and love for the community who made us who we are."
