GOG is giving away Sigma Theory: Global Cold War, a strategy game set in a future where global superpowers compete over technological advances by sending agents and drones around an XCOM-style hologram of the globe. It’s a game of turn-based espionage that lists Tropico, Armello, Civilization, Plague Inc. and the board game Pandemic among its inspirations.
Sigma Theory was designed by Mi-Clos Studio, the creators of the Out There series, which is reflected in its regular transformations into a choose-your-own-adventure game—when you’re commanding agents in the field, for instance. Each of those agents comes from a selection of 50 named spies, all with their own backstory and personality traits that influence how well they perform and suggest which course of action you should tell them to take when being chased through the streets or trying to hijack secret documents.
