About Sigma Theory: Global Cold War

In the near future, a paradigm-shifting scientific discovery looms over the world, promising radical new technologies. The world's superpowers realize they could have the power to destroy the global financial system, wipe out entire countries or even gain access to immortality. However, this discovery — called "The Sigma Theory" — can only be harnessed by a handful of scientists. You are placed at the head of your country's Sigma division. Your objective is to ensure that it is your nation that reaps the benefits of Sigma Theory before anyone else.

To achieve this you will have powerful resources at your disposal: a cadre of the world's most elite covert agents, advanced tactical drones and, of course, your own skills in diplomacy and subterfuge. It's a cold war out there, one in which mankind must face up to its future. Use your special agents to dominate the world. Seduction, blackmail, manipulation, industrial espionage… Every low blow is both permitted and encouraged. Develop and manage your relations with over 100 NPCs: lobbies, armed groups, politicians… Alliance, deception or assassination, you choose.
