Prime Video is reportedly beginning its Warhammer 40,000 screen universe with a Secret Level season centred on the Deathwatch, a force made up of veteran Space Marines from different Chapters. The article argues this is a strong starting point because it can introduce new viewers to the setting’s major factions, rivalries and alien threats without committing the franchise to one Space Marine Chapter too early.

Henry Cavill said Amazon is developing the project with director Dave Wilson, writer John Orloff and Blur Studio, with Cavill and the wider Warhammer team helping it fit an overall universe plan. Deathwatch kill teams can include Marines such as Ultramarines, Space Wolves, Dark Angels and Black Templars, while their missions against xenos could feature Tyranids, Orks, Necrons, T’au, Aeldari and Genestealer Cults. The article also notes that Wilson and Blur Studio have prior experience depicting Space Marines through Secret Level.
