Press release:
PARIS (May 21, 2026) – Execute your enemies in a grand journey to join the ranks of the world’s deadliest assassins in Warhammer Age of Sigmar: Deathmaster, a new self-contained, single player 2D action platformer from developer Old Skull Games and publisher Dotemu (Absolum, MARVEL Cosmic Invasion). A fresh, ambitious take on the globally beloved Warhammer franchise inspired by the greatest 2D action platformer and stealth-enriched classics, Warhammer Age of Sigmar: Deathmaster was revealed in a striking announcement trailer at today’s Warhammer Skulls event, launching on PC and consoles in 2027.

Embark on a dark tale of treachery as the hooded Ratman Vihneek, an ambitious killer devoted to ascending to the top of his shadowy Eshin clan at all costs. Vihneek’s sinister masters demand unwavering loyalty, but a Skaven’s ambition knows no limits, even when scheming on the precipice of doom. Vihneek’s story is anchored in the rich lore of the Age of Sigmar, where the Skaven have erupted to seize the Mortal Realms for themselves..

Set traps, exploit your surroundings and outwit enemies as you ruthlessly carve your fate through the darkest corners of the Skaven world. Slink past threats undetected while devising cunning plans, savagely slaughtering any Skaven who foolishly stands in your way, from cowering dregs to towering rat ogors.

Warhammer Age of Sigmar: Deathmaster’s gritty, atmospheric environments are beautifully twisted with relentless decay, accented with shadows and dark spaces prime for Vihneek to sneak through – and strike from. A richly detailed art style evokes suspense and thrilling tension while delivering a unique, unsettling vision of a Skaven world teeming with secrets that should never be unearthed.

Get the drop on all Warhammer Age of Sigmar: Deathmaster updates by following @Dotemu and @OldSkullGames on X.
