Warhammer Age of Sigmar: Deathmaster has been announced by Dotemu and Old Skull Games — a self-contained 2D action platformer launching on PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X|S in 2027. The reveal happened during the Warhammer Skulls Showcase, and it’s the first-ever game to star the Skaven — the treacherous rat-people of the Warhammer Age of Sigmar universe. You play as Vihneek, an assassin climbing the ranks of the shadowy Eshin clan through a combination of stealth, traps, and savage murder. This is Dotemu doing grimdark, and given their track record with Streets of Rage 4 and TMNT: Shredder’s Revenge, that is a sentence worth getting excited about.
The game is explicitly designed for players with no prior Warhammer knowledge — accessible as a standalone experience while still rewarding series fans with deep lore connections to the Skaven’s eruption into the Mortal Realms. Vihneek’s story is one of ruthless ambition within a clan that rewards treachery: his masters demand loyalty, but a Skaven’s ambition knows no limits, even on the edge of doom.
What Kind of Game Is Deathmaster?
Deathmaster sits at the intersection of classic 2D action platformers and stealth games — the press release cites the “greatest 2D action platformer and stealth-enriched classics” as the primary inspirations. The core fantasy is an assassin moving through the darkness of a Skaven world: slink past enemies undetected, set traps to catch them off-guard, and savagely butcher anything that spots you anyway. Enemies range from cowering underlings to towering rat ogors, and the environments are designed around shadows and dark spaces that reward patient, cunning play.
The setting is the Skaven world itself — not the human-facing Age of Sigmar battlefields but the decaying, secretive underbelly of it. Gritty atmospheric environments built around relentless decay and dark architecture, with an art style described as visually striking and distinctly unsettling. This is the Warhammer universe from the perspective of its most beloved villains, given a full platform game to inhabit.
Why Dotemu Matters Here
Publisher pedigree is worth calling out explicitly for this announcement. Dotemu has earned the trust of fans of classic action games through a consistent run of high-quality revivals and new IPs:
Old Skull Games, the developer, is a 60-person studio with a gameplay-first philosophy and experience across PC, console, and mobile. Deathmaster is their highest-profile announcement to date.
