The grimdark setting of Warhammer 40k has seen a surge in popularity, with its dedicated fan base and high-profile video game releases, such as Space Marine 2. While 40k reaches a broader audience, it remains one of the most brutal settings in sci-fi history. The Imperium of Mankind spans the galaxy, on over a million worlds. The trillions of humans living under the Imperium exist in the most oppressive and draconian society imaginable.
