Sigma Theory is a Turn-based Strategy game in a futuristic global cold war from the award-winning creators of Out There. Recruit a squad of special agents and run your intel agency to secure the control of the singularity. STORY 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.}

The lack of a tutorial was an incredibly bad decision. This game, although not difficult, is very far from intuitive. There are quite a few ways to get an edge over other countries and what to focus on during espionage, so as long as you've got the basics down, it's a good time to explore with agents. And that's about it... Replayability is limited by your interest in the spies and whether you're willing to make them work, but it can only get you so far. Overall, it's ok for play pass.

I've played for a few in-game weeks, and I don't really get the point. Even the tutorial doesn't actually explain much. My own country dislikes me and I don't know why or how to fix it. They took drones away, and I don't know why or how to fix it. The _only_ missions ever available are hacking. Hacking doesn't seem to get anything useful on nation leaders. The game is doing things without telling me why or how to do anything about it.

I feel like they did a really good job with this one and it lends itself to some replayability. Not as much as some others but it's still there. The idea and core concept is interesting enough to feel fresh and the gameplay loop is enjoyable. You can tell they did a really good job with balancing all of the agents because it's genuinely hard for me to pick which ones I want on any given playthrough. I still haven't gotten to the end but I'm liking it a lot so far.

Está en ingles y va de gestionar una agencia de 4 espías. Hay muchos espías y varias formas de jugar consiste en reunir un grupo de científicos y de qué no te los roben.

decent game, good replayability, good decision making, nice graphics, cute story, cute endings, but it gets too repetitive. wife mechanic also sucks is more of a negative wildcard than anything. great experience overall, played for 3 days like crazy.

Excelente. Muchas posibilidades y maneras de actuar para conseguir los objetivos, desbloqueo de nuevos agentes según lo que hagas, etc. Me gustan los detalles y la trama, además parece ser que el final cambia según tus decisiones. La verdad es que es interesante y está muy bien.

Nota: Dar una estrella porque no está en español es como si un inglés diese una puntuación de una estrella a un QUIJOTE en castellano, ¿Que pensaríamos de él? ! Exacto!, que es ciliboyas. El juego es muy bueno, tienes que analizar todas las situaciones y enviar al agente que tenga menos probabilidad de fallar. No está en español, lo que dificulta el juego a los "únicocastellanoparlantes". si dominas algún idioma de los que ofrecen las opciones y te gusta el tema, lo disfrutarás mucho, si no no.

this game such a wasted potential, i mean its ok and fun enough but very shallow and luck based rng alot,lazy made, feels unpolished, unfinished and the custom mode is not developed enough either, such a shame, its kinda addictive but... also they only made the "spouse" mechanic likmr and mrs smith style, like this "spouse " can be lethal , in like one event it pulled out the possibility for me to get -10 on the doomsday clock just like that aand GAME OVER, like thats such a POOR lazy design
