Alternative reality video games (ARG) have emerged thanks to their flexibility when using as a platform in the real world, proposing new forms of interaction. The objective of this study is to determine how a multimedia systems integration model can be integrated into an ARG game. To this end, the research question is as follows: How can a multimedia system be integrated into an alternative reality game? The research question is answered through the development of an integration model that is supported by the network narrative, which is generally the most widely used in this type of game, giving the possibility of integrating multimedia systems such as nodes of diffusion and interaction of the game narrative.
