To change the radio station in Big Walk, players must locate and activate specific transmitters scattered throughout the game world. These transmitters are recognizable as green boxes topped with an antenna, and each is marked with a red line indicating its corresponding station number.
Transmitters are typically found near colorful, abstract structures that broadcast the station's music. Players who hear music that isn't coming from their in-game radio are likely near a radio station.
One specific station, number five, requires a bit more effort to reach. Players must first complete the yellow tower to unlock access to the tunnels. Once inside, take the yellow tunnel and immediately turn right at the fork. Do not proceed toward the red tower; instead, hug the wall and ascend the stairs. This path leads to a nightclub where the transmitter for radio station five is located.
Big Walk features a total of seven radio stations, each with its own unique soundtrack, offering players ambient travel music. Activating these transmitters not only provides new listening options but also allows players to turn off the radio or switch between stations to avoid repetition during their journeys.
