Announced in August 2026, a new animated spin-off series for Prime Video will expand on the Warhammer 40,000 story introduced in the anthology show Secret Level. Executive producer Henry Cavill and director Dave Wilson are leading the project to develop the narrative further.
Why it matters
The spin-off directly addresses audience feedback regarding the limited scope of the original 19-minute animation. By extending this specific narrative, the producers aim to deepen the presence of the Warhammer 40,000 universe on the streaming platform.
