Silent Code is a simulation game set against the backdrop of the Chinese Red Revolution, using VR technology to allow players to experience the revolutionary process firsthand and experience the harsh environment and spirit of struggle at that time. The game is divided into multiple levels, each with a theme of a real historical event that occurred during a revolutionary period on a traffic driver. Players need to immerse themselves in the game scene through VR devices, and simulate various gameplay such as rock climbing, stealth, and puzzle solving. Following the guidance of game narrators, they gradually experience the entire process of transmitting intelligence by traffic drivers during the revolutionary era. As the gaming experience deepens and the narrator narrates historical events, players will find that the entire game process is not only a simulation of the gaming experience, but also a touching and real historical event.
