Guerrilla Games, the Amsterdam studio behind Horizon Zero Dawn, opens its doors to filmmaker Bregtje van der Haak during the final sprint before the game's release. Two hundred forty people worked on the title for five years on a multi-million-euro budget, and the film follows the writers, artists, and engineers who built its open world, including art director Jan-Bart van Beek, game director Mathijs de Jonge, and producer Angie Smets. The camera catches the motion-capture shoot in Oxford that gave the lead character Aloy her movement, a composite built from a Dutch actress's face, an American voice, and a British acrobat's body. It also visits the Anaheim preview event, where thousands of fans, many cosplaying as Aloy, turn the unveiling into a convention-scale spectacle. Media scholar Mark Deuze steps in periodically to place the $100 billion game industry and its four-hours-a-week Dutch player base in wider context, asking what happens when a hobby this immersive becomes a way of life.
