A twenty-minute behind-the-scenes introduction to the dark, sci-fi world can be viewed on the developer's YouTube channel. "Vision of Marathon" includes commentary from music composer Ryan Lott, founding member of the American experimental band Son Lux.
Marathon invites players to scavenge the lost colony of Tau Ceti IV as a bio-cybernetic Runner, detailed in the release date announcement post. "As you complete contracts for each of the six factions, you’ll learn more about their identities, motivations, and rivalries as you work together to uncover the mysteries of Tau Ceti’s fate."
Launch cinematic music video, set to "In Death We've Just Begun ft. Poppy and Son Lux," is streaming on YouTube Music, alongside single "Timeleach."
