What Is Sigma Theory?

Sigma Theory is a premium, turn-based espionage simulation that offers a unique, narrative-driven experience for strategy enthusiasts. By focusing on geopolitical themes and complex decision-making, it carves out a distinct niche in the mobile market. However, the product is currently hindered by significant technical and UX hurdles. While the core concept is highly praised, the lack of an effective tutorial and recurring issues with DLC monetization are actively damaging user sentiment and retention.

The lack of a tutorial was an incredibly bad decision.
