If you didn't manage to nab a copy of Chris Avellone's Fallout: New Vegas - All Roads graphic novel that was included in the collector's edition of said game, you'll be happy to learn that it's now available via digital download through Dark Horse Comics' website or iOS app. A few background details, for the unfamiliar:
All Roads introduces the world of New Vegas, a town of dreamers and desperadoes being torn apart by warring factions vying for complete control of this desert oasis, and tells an intriguing tale of loyalty and violence that leads right up to the beginning of the game. Written by Chris Avellone, the game's senior designer, All Roads is tightly integrated into the story of New Vegas, even containing clues to in-game missions for the sharp-eyed reader. Artists Jean Diaz (Incorruptible) and Wellinton Alves (Shadowland: Blood on the Streets, Nova) and cover artist Geof Darrow (Hard Boiled, The Matrix Comics, The Big Guy and Rusty the Boy Robot) stunningly interpret the world of New Vegas!
