Secret Level is Prime Video's latest big budget video game to TV project, following on from its massively successful adaptation of Fallout earlier this year.
Hollywood's increasingly been looking to games - which often have ready made, enthusiastic fanbases - as a source of new shows and films.
Amazon and Games Workshop just announced a deal for the streamer to create films and TV series set in its Warhammer universes.
One of Secret Level's episodes is based on Warhammer 40,000: Space Marine 2, a big hit this year for developer Saber Interactive.
Secret Level's director Dave Wilson says the game's universe has "40 years of lore" behind it, which has to be balanced with the needs of a TV adaptation.
He gives the example of the space marines, who live by the credo "they shall know no fear".
"If you take that too literally you can't really have a hero make a choice if he's not afraid of the consequences of that choice, right?," says Dave.
"So there is the literal interpretation of what that means, and then there's the storytelling interpretation."
