Alt-Frequencies is an audio-based narrative mystery game taking place between multiple radio stations. Its gameplay is mostly based on narrative puzzles players have to solve to progress through their investigation.
Players can browse between several radio stations to listen to their broadcasts. They can record clips of what they hear and isolate information, and then send recorded clips to other stations, which might influence the world.
The story explores real-world situations and daily interactions and aims at raising awareness about a social issue, namely our relationship with mainstream media and the treatment of information.
