Halo. When you read this name, a soundtrack starts playing in your ears and tons of images flash in front of your eyes. A whole universe appears in your mind. More than an first person shooter in space, Halo is the highest grossing franchise series of all time with over 80 million copies sold worldwide. The video game has spawned a whole world of content including comic books, novels, films, and a myriad of toys and products. Developed by Bungie and produced by 343 Studios, this books it the ultimate history of the Halo franchise, from its sci-fi inception in 2001 to the release of Halo: Infinite in December 2021. Halo is a passion for Loïc Ralet , who has been collecting for years all sorts of information about the games and its creators: press articles, interviews, videos. To write this book, he spent a year sorting through his notes, dissecting the games’ levels and interviewing the fathers of Master Chief: Alexander Seropian (cofounder of Bungie), Marcus Lehto (art director and creator of the Master Chief) and Martin O’Donnell (composer of the soundtracks), among others.
