Sumerian Six, the real-time tactical stealth adventure from developer Artificer and publisher Devolver Digital, launches now on PlayStation 5 and Xbox Series X|S. The game has been available on PC through Steam and arrives on consoles in partnership with Crunching Koalas.
Set in an alternate version of World War II where the occult is as real as the bullets, Sumerian Six puts you in command of the Enigma Squad, a team of six scientists trained as commandos. Each one brings abilities drawn from their field of expertise, and together they're tasked with stopping Hans Kammler, a former squad member who defected to the Third Reich. Kammler is tapping into a mystical substance called Geiststoff to build the ultimate weapon, and the squad's mission spans multiple continents as they work to dismantle his plans. The team itself is the draw here. Rosa Reznick is an exiled chemist whose toxic concoctions serve as tools of sabotage. Wojtek Galica, known as "The Werebear," brings mutated brute strength to the equation. Siegfried von Adelsberg rounds out the roster as an esoteric psychoanalyst, his abilities pulling from stranger territory entirely. Six specialists, each with a distinct kit, each filling a different tactical role.
The core of the game is stealth and timing. You infiltrate Nazi strongholds, picking apart patrol routes and dispatching guards in a variety of ways before confronting the larger threats lurking deeper inside. The real satisfaction comes from chaining abilities together across your squad members, combining their powers into coordinated strikes that hit harder than any single action could. Rosa's chemical mixtures paired with Wojtek's raw force, or Siegfried's more esoteric talents setting up opportunities for the rest of the team. Mastering those chains is what separates clean runs from messy ones, and the game demands you learn them if you want to succeed.
The enemies escalate well beyond standard soldiers. Kammler's forces include heavily armed troops, mutated creatures, and supernaturally charged opponents, all products of the Reich's occult experiments. Ancient Sumerian artifacts and occult scientific weapons surface as you push deeper into the conspiracy, raising the stakes with each chapter. Ten missions carry you through the campaign, each set across locations inspired by real places and historical events, twisted through the lens of a world where folk stories and conspiracy theories turned out to be true.
The tone sits in a specific place, mixing pulp adventure with genuine menace. There's a playfulness to the violence and the super science, a willingness to lean into the absurdity of a werebear commando fighting demon Nazis. But the alternate history framing keeps the stakes grounded. The Third Reich winning this version of the war means something darker than conventional defeat, and the game doesn't let you forget that the timeline you're fighting to prevent is a grim one.
Sumerian Six builds its ten chapters around precision and patience, asking you to read each stronghold carefully before committing to action. With each successful mission the squad grows stronger, and the threats waiting in Kammler's inner circle grow stranger. It's a game about six scientists who became soldiers, chaining their brilliance together one tactical strike at a time.
