STORY

From the creators of the award-winning sci-fi game Out There...

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.

THE ULTIMATE ESPIONAGE SIMULATION

Turn-based espionage: Use your special agents to dominate the world. Seduction, blackmail, manipulation, industrial espionage… Every low blow is both permitted and encouraged.
Dynamic narrative: Develop and manage your relations with over 100 NPCs: lobbies, armed groups, politicians… Alliance, deception or assassination, you choose.
Field operations: Direct the kidnapping of your targets during gripping pursuits through the world’s greatest cities. Discretion or direct confrontation, your agent’s life is in your hands.

Recruitment
First, recruit a team of four special agents from 50 unique unlockable characters to support your missions. Each comes with their own story, motivations and traits that define their behavior during missions.
Access the investigator, soldier, hacker, seducer and other archetypes to complete your Sigma division and execute your strategy.

Espionage
When your team is ready, assign them missions around the world to gather scientists, discover compromising documents on local politicians, and more.
Exploit your agents’ abilities to seduce, manipulate and bribe your targets over to your side or have them neutralized.

Counter-espionage
Other nations will also use their agents to infiltrate your country and seize your scientists. Track, capture and interrogate them to gain information on your enemies, then exchange them for ransom when they are no longer useful.

Exfiltration
Order your agents to exfiltrate scientists recruited to your cause during gripping turn-based exfiltration phases through the world’s greatest capitals. Choose the position your drones wisely to support these delicate missions.

Diplomacy
In Sigma Theory, diplomacy is the key to achieving your goals. Meet your foreign counterparts and further your objectives using flattery, threats or blackmail. You can also recover your captured agents, advance your research, and much more. Develop your relations with powerful lobbies and armed and influential groups to obtain their favor. But be careful, they may turn on you.

Tech Tree
Sigma Theory is the cause of this cold war. Rally scientists from around the world to your cause to discover new technologies to gain the edge and change the world. Mind control, destabilization of the world economy, robot soldiers, immortality… Will you keep these discoveries for yourself or share them with the world?

Best Espionnage sim to date

A fascinating game that puts you in change of managing a team of secret agents as a new Signa technology appears to catch all the attention worldwide. This technology has multiple applications in different fields, such as Finance, Robotics, Health, etc. and your goverment needs to be on top of the global research. Send your agents to gather information about foreign scientists, or use hackers first. Once you've located the assets, investigate to know more about them, and what do they really crave. Are they corruptible? What is their sexual orientation? Maybe through seduction you can get them to work for you. Or just brutally organizing a kidnapping, though the subtle way is preferrable. Acting ruthlessly will have political repercussions, and you wouldn't start a war, would you? Also, as your agents are humans after all, some things can slip out of control very quickly... One of your agents falls in love with a source. Or your spouse gets kidnapped and a foreign country wants to acquire your research in exchange. What about if an exfiltration goes wrong and your agents gets captured? Will you recover your agent through diplomacy, or attempt a rescue mission? Overall, an immersive game with a strong emphasis on narration, a captivating theme and a lot of subtle random events that makes each playthrough slightly unique.

Strategy & Luck balance

It's tough, but I beat the classic mode after quite some tries. It's a challenging game, and the mechanics are a bit confusing at first. Sometimes the amount of new alerts per turn is going to be overwhelming and you are likely to let something critical slip by. It also involves a bit of luck not to strike midnight in the doomsday clock, since that depends on the other nations' choices too. There are a few bugs but none was a deal-breaker.

a bit shallow

The game is fun for half an hour but there is a lot of "fluff" and the game loop is actually pretty shallow. I got it for free though, so I do not complain.
