En ésta oportunidad comenzamos con la configuración inicial y la realización de la lógica de creación de salas unión  a salas, y ubicación de objeto player en la escena en ésta serie abarcaremos la creación de nuestro videojuego TPS en la modalidad Multijugador con Photon 2 en Unity 3D. La implementación multijugador es independiente del juego la haremos así para que puedas utilizarla en cualquier otro proyecto que requieras.
