Sigma Theory: Global Cold War

Sigma Theory: Global Cold War is a turn-based espionage game set in the near future. A scientific discovery called the Sigma Theory promises technologies that could destroy the global financial system, wipe out entire countries or grant immortality. Only a handful of scientists can harness it, and you lead your country’s Sigma division, working to ensure your nation gains its benefits before its rivals do. You command elite covert agents and tactical drones, and use diplomacy and subterfuge in a global cold war.

Build your division

Recruit a team of four special agents from 50 unique unlockable characters. Each has a personal story, motivations and traits that shape their behavior during missions. Choose from archetypes such as investigators, soldiers, hackers and seducers to assemble a team suited to your strategy.

Espionage and operations

Assign agents to missions around the world to recruit scientists and uncover compromising documents about local politicians. They can seduce, manipulate or bribe targets to bring them over to your side, or have them neutralized. Industrial espionage, blackmail and other forms of manipulation are also available.

Field operations include kidnapping targets during pursuits through major cities, where you decide between discretion and direct confrontation and control the risks to your agents. During turn-based exfiltration missions through the world’s capitals, you guide scientists recruited to your cause to safety and position tactical drones to support them.

Counter-espionage

Rival nations send agents to infiltrate your country and seize your scientists. You can track, capture and interrogate those agents to learn about your enemies, then exchange them for ransom when they are no longer useful.

Diplomacy and research

Meet foreign counterparts and pursue your objectives through flattery, threats or blackmail. Diplomacy can also help you recover captured agents and advance research. Build relations with powerful lobbies and armed and influential groups to gain their favor, while bearing in mind that they may turn against you.

Recruit scientists from around the world to research technologies that can shift the balance of power, including mind control, destabilizing the world economy, robot soldiers and immortality. You decide whether to keep these discoveries for your country or share them with the world.

Dynamic relationships

Manage relations with more than 100 non-player characters, including lobbies, armed groups and politicians. You choose whether to form alliances, deceive them or have them assassinated.
