Sumerian Six is a real-time tactical stealth game that places players in command of the Enigma Squad, a group of elite scientist commandos battling Nazi forces in an alternate history setting infused with occult and supernatural elements.
Gameplay
The core loop revolves around infiltrating enemy strongholds from an isometric view while managing line-of-sight cones and patrol routes. Detection typically leads to overwhelming reinforcements, so success depends on precise timing and positioning. Each squad member brings specialized abilities drawn from their scientific backgrounds, allowing players to eliminate isolated threats through melee takedowns or more elaborate ability combinations. An action planner tool enables coordinated strikes across multiple characters in quick succession, turning individual skills into chained sequences that clear groups without raising alarms. Levels feature varied environments inspired by real-world locations, with objectives that include eliminating key targets and navigating through increasingly complex Nazi defenses that incorporate mutated and supernaturally enhanced units.
Game Modes
The game centers on a single-player campaign divided into ten missions. Each mission tasks the squad with completing primary goals such as neutralizing threats or securing artifacts while optional speedrun challenges encourage faster completion times, often targeting 25 to 35 minutes per stage. Progression involves unlocking and refining team abilities across the campaign, with no separate multiplayer or competitive modes available. The structure emphasizes replayability through different ability combinations and approaches to the same objectives rather than additional game types.
Story and Setting
Players follow the Enigma Squad as they pursue former member Hans Kammler, who now leads Nazi efforts to harness a mystical substance called Geiststoff. The narrative unfolds across multiple continents and incorporates elements like ancient Sumerian artifacts and experimental occult-scientific weapons. Key allies include chemist Rosa Reznick, the werebear Wojtek, and psychoanalyst Siegfried von Adelsberg, each contributing unique perspectives and capabilities to the missions. The story builds toward preventing a grim alternate future dominated by these enhanced Nazi forces.
