Another ViDoc has been released for Gears of War 2, entitled "Making Gears 2: Delta Blues," in which the Development Team at Epic Games goes into the details of how they make the boys of Delta tick. It'll also introduce us to some of the new characters in the game, and is a cool look at the mentality behind the Squad (I though Carmine was dead!).
It's another great watch, and you can view it on the official site right here (top left), or below. Haven't spotted this one on the Xbox LIVE Marketplace yet, but I'm sure it's coming soon enough.
