Lyon, France - February 7th, 2019 - The French independent developer Mi-Clos Studio has announced today that their new near-future spy simulation game Sigma Theory: Global Cold War will officially launch on Steam (PC, Mac, and Linux) on April 18th, 2019. Currently in a private beta, Sigma Theory allows players to set up their own intelligence agency, recruit elite spies, and bribe, seduce and assassinate their way to world domination.


To celebrate the release date, a new trailer for Sigma Theory has been released and can be viewed here.


In the turn-based single-player Sigma Theory, the world is plunged into a new global cold war after the discovery of a ground-breaking scientific discovery that will radically change humanity’s destiny. Players take charge of their own agency - staffing it with their best, brightest and most ruthless - in order to get their chosen nation ahead in a deadly conflict that is fought in the shadows. Heavily inspired by real-life events, and shaped by the hands-on intelligence experience of the developers who previously created the award-winning Out There, Sigma Theory allows for a fascinating glimpse into a near future that is closer to reality than many would think.


Not only the elite agents, but cutting-edge technology will also play an important role in Sigma Theory. From drone fleets to hacking, players will have to use all the tools at their disposal to eliminate hostile agents and to protect their own. Players will send their spies on a variety of missions across the globe: to gather intel, cooperate with armed groups, engage in high-level diplomacy, steal crucial tech, recruit new scientists or forcibly extract them if they refuse to go willingly. A mix of tactical and strategic turn-based gameplay, Sigma Theory’s dynamic story will change depending on the player’s choices, allowing for multiple distinct endings.


Pre-orders of Sigma Theory are available now, which give immediate access to the private beta. The game is set for a full launch on Steam (PC, Mac, and Linux) on April 18th, 2019. More details about the game can be found on the official website, or by checking the game’s Twitter or Facebook pages.
