Just like cinema, games are an audiovisual product, but with the differential of interactivity with players. As a new media, electronic games have shown themselves to have great communicational potential, and the evolution of technology has led to the need to create a promotional strategy for games. Thus, taking as a reference the audiovisual strategies for advertising films according to Vanoye and Goliot-Lété (1994), this book seeks to analyse the changes that have occurred in the strategy and audiovisual aesthetics of the trailers for the Call of Duty game franchise, from the animations to the current live-action trailers.
