About Sumerian Six
Sumerian Six is a real-time tactical stealth adventure about the Enigma Squad, a team of commandos made up of the world’s greatest scientists. You carry out secret missions across multiple continents to stop former squad member Hans Kammler from using Geiststoff, a powerful mystical substance, in his plans for the Third Reich.
The Enigma Squad
The squad includes allies such as exiled chemist Rosa Reznick, Wojtek the Werebear and esoteric psychoanalyst Siegfried von Adelsberg. Each team member has abilities inspired by their field of expertise. You use these skills to deal with enemies and can chain them together for more powerful effects.
Infiltrate Nazi strongholds
You sneak through Nazi strongholds and dispatch their watchmen in different ways before facing more serious threats. The Nazis, led by Kammler, use occult forces to create the ultimate Wunderwaffe. Their forces include heavily armed, mutated and supernaturally charged enemies, while occult-scientific weapons and ancient Sumerian artifacts are tied to Kammler's plans.
An alternate history
The journey draws on real places and events, but takes place in an alternate history where folk stories and conspiracy theories are real alongside the Nazi threat. You must prevent a grim future in which the Nazis win.
