When you think of Fallout, the first image that probably comes to mind is a grinning Vault Boy, decked out in his trademark blue and yellow jumpsuit, giving you the thumbs up. As the mascot of Vault-Tec, the character appears in everything from television adverts to product manuals - in fact, across both the games and the marketing surrounding them, Vault Boy is impossible to avoid. He is everywhere.
But why is he usually pictured giving us all that big thumbs up? Well, that's something gamers have questioned over the years, but no definitive answer has ever been given. There have of course been several rumors including that he's meant to be a reassuring presence, it helps to measure the cloud of a nuclear bomb, and even more simply, that he has a positive attitude. Nothing has ever been confirmed though, until now.
