iPhone and iPad owners can now download an app called Fallout: New Vegas - All Roads. It's a 12-page preview of a graphic novel penned by New Vegas senior designer Chris Avellone.

All Roads is "an intriguing tale of loyalty and violence" set before the events of the game. It introduces gamers to the city of New Vegas and the factions battling for control. Supposedly the comic provides some hints for in-game quests, too.

The full, hardcover version of the graphic novel is included with the Collector's Edition of the game.
