Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 4 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Best map game of all time. Once you start prioritizing hacking and diplomacy, the game becomes a lot less punishing. Wolf the goat.
Tacticas tipo XCOM (con la guerra mundial), loop jugable muy bueno y dificultad interesante. Si te gustan este tipo de juegos de estrategia militar tipo RISK es de los mejores que he probado. La primera vez que abrí el juego jugué durante 5 horas seguidas
Sigma Theory hat mich sofort gefesselt, weil es klassische Spionage mit cleverem Strategie-Gameplay verbindet. Man übernimmt eine geheime Organisation in einem futuristischen Kalten Krieg, rekrutiert Agenten, plant Missionen und versucht, Informationen und Einfluss zu gewinnen. Dabei fühlt sich jede Entscheidung wichtig an – wer geht auf welche Mission, welche Ausrüstung bekommt welcher Agent, welche Länder vertraut man an? Alles hat Konsequenzen, und genau das macht den Reiz aus. Was mir besonders gefällt, ist die Mischung aus Planung und Risiko. Man kann nicht alles kontrollieren, aber man kann clever handeln, Agenten einsetzen und Strategien entwickeln, die das Spiel oft überraschend dynamisch machen. Jeder Durchlauf läuft anders, und kleine Entscheidungen können große Auswirkungen haben. Auch die Atmosphäre gefällt mir sehr. Die futuristische, kalte Ästhetik, die klaren Interfaces und die spannungsgeladene Story tragen dazu bei, dass man sich wirklich wie der Kopf einer Geheimorganisation fühlt. Es ist ruhig, aber immer angespannt – genau wie Spionage sein sollte. Klar, es ist kein actiongeladenes Spiel, und wer schnelle, direkte Kämpfe sucht, wird hier nicht fündig. Aber als taktisches, nachdenkliches Strategiespiel funktioniert Sigma Theory für mich hervorragend. Für mich ist Sigma Theory: Global Cold War ein cleveres, spannendes und stilvoll inszeniertes Strategiespiel, das Taktik, Risiko und Story auf gelungene Weise verbindet.

Ca attire l'oeil, on s'imagine un univers très inventif, mais il n'y a pas grand-chose derrière. Les mécaniques de jeu sont ennuyeuses et plates, et en fait de scénario inventif il n'y a que des mots un peu ronflants.
Good.
Its a puzzle game. Its also quite difficult. Havent really gotten into it yet (5h of gameplay) but some youtube videos has made me eager to once more try out the challenge. My earlier "cons" on this game was that game length is shorter than expected. I wanted a grindy slowpaced (in the infinite) spygame. This is more of a forced situation where someone wins in a "endgame race". Although you dont have to stress in every situation - its needed to risk at some situations if you want to keep up in the race for the winning. My "absolute pros" is a wide variety of agents! To not totally end up playing same favourites every game there is also a "monthly challenge" where everyone playing gets same starting set of 4 agenst (witch is very varied to pick the ones you usually go for). I assume some on steam says a game is dead when its not frequent updated. In my older (classical take) a game normally was released as a product a finnished state and any further developements would be a next successor. The game is fully playable and it is unique in many ways. As first said its a puzzlegame and you will try to play out your cards is a best way, with good timing aswell, to progress in front of your competition. Unique in many ways and absolutely worth trying out.
It's one of those games where you do see a lot of effort was made but it doesn't actually translate into a game. It's not that it's good or bad, it's rather there hardly is any game in it - the choices you make don't matter as RNG is very capricious and the strategy is just to lunge at any opportunity you see.
Played once thru so far. I almost resigned since I was so far behind in research, but i caught up and passed everyone to win. Was that a fluke or a flaw in the game? There's just enough to do each turn to make the gameplay interesting. You have to think a few steps ahead when you want to grow your pool of scientists without losing agents. Graphics are simple but appealing and the iconography is clear. I especially like identifying and recruiting scientists - real OPSEC stuff. Looking forward to trying again with new agents.
eğlenceli bir strateji oyun.oyunla ilgili en büyük eleştirim içerğiğin bi 10-20 saate kendini tekrar etmeye başlaması olur.DLC'lerde de yeterince yeni şey eklenmiyor.İndirim döneminde alınabilir.
Sigma Theory: Global Cold War, developed by Mi-Clos Studio in collaboration with Goblinz Studio and FibreTigre and published by Goblinz Publishing and Fractale, is a sleek and cerebral turn-based strategy game that reimagines espionage in a futuristic world on the brink of a scientific revolution. Set in a near-future where a discovery known as the Sigma Theory has the potential to reshape the world, every major nation races to seize control of it. You are appointed as the head of your country’s intelligence agency, tasked with recruiting a team of elite agents, navigating fragile international diplomacy, stealing secrets, and manipulating global powers to secure dominance. The premise immediately establishes an atmosphere of tension and secrecy—one that blends political intrigue with the moral grayness of covert warfare. Unlike traditional grand strategy games that focus on armies and territory, Sigma Theory is about information, manipulation, and psychological warfare, delivering an experience that’s as cerebral as it is thrilling. The visual presentation is minimalist but stylish, emphasizing clarity over flash. The clean interface and sharp color palette give the game a professional intelligence dossier aesthetic, perfectly suited to its espionage theme. Every screen—from the world map to agent dossiers—feels like a classified briefing brought to life. The music complements this tension, with electronic undertones and ambient beats that create a feeling of constant unease. While the game’s art direction favors abstraction over realism, it reinforces the sense of detachment and control that comes with the role of spymaster. Rather than immersing players through cinematic spectacle, Sigma Theory pulls them into its world through the quiet pulse of strategic decisions and the dread of consequences that unfold from each choice. It’s a world where words and secrets carry more weight than bullets. At its core, Sigma Theory revolves around managing your network of agents, diplomats, and scientists. Each turn, you send operatives across the globe to perform missions ranging from recruiting scientists and stealing research to orchestrating assassinations or exfiltrations. Each agent has their own skills, specialties, and personal quirks—some are masters of seduction or persuasion, others excel at infiltration or cyberwarfare. Building the right team is essential, not just for mission success but for managing the personalities and loyalties of those under your command. As missions unfold, random events and moral dilemmas emerge, forcing you to make difficult choices: sacrifice an operative for the greater good, betray an ally for technological gain, or risk diplomatic fallout for a bold strike. Beneath its simple surface, the game demands careful foresight. Every decision affects your country’s international standing, your relationships with rival nations, and your access to the world’s most valuable scientific breakthroughs. Diplomacy and subterfuge are the two pillars that define the player experience. Maintaining relationships with other nations is as crucial as sabotaging them, as overt hostility can lead to open conflict or global instability. The balance between overt cooperation and covert manipulation gives the gameplay a sense of constant tension. One wrong move—an assassination discovered, a spy caught red-handed—can shift alliances overnight. The game effectively captures the paranoia of a Cold War environment, where every country appears friendly in public but acts ruthlessly in secret. Meanwhile, research progress serves as the silent countdown to victory; whoever first harnesses the Sigma Theory gains technological supremacy capable of redefining humanity’s future. This premise ensures that every action feels meaningful, as each mission can alter the global balance of power in subtle yet profound ways. Despite its captivating ideas, Sigma Theory is not without limitations. The game’s systems, while engaging, tend to repeat over time. Missions often fall into familiar patterns, and once players master the optimal strategies for managing alert levels and agent deployment, the surprises become less frequent. The campaign is also relatively short—many players can complete it within a few hours—leaving some wishing for deeper or more emergent gameplay. The RNG-driven outcomes can occasionally feel frustrating, with success hinging on dice rolls rather than strategy. These drawbacks do not ruin the experience, but they limit the game’s long-term appeal. Still, its brevity works in its favor for those who enjoy tight, replayable experiences. Each run offers a slightly different challenge thanks to varied starting conditions, agent combinations, and unpredictable global events. What truly makes Sigma Theory compelling is the way it captures the feeling of control and unease that defines intelligence work. It’s not about commanding armies or managing resources—it’s about operating in shadows, making compromises, and pulling strings from behind the scenes. The game rewards those who approach it with patience and subtlety rather than brute force. When a carefully planned operation succeeds or when you manipulate a rival nation into doing your bidding, the sense of satisfaction is immense. Conversely, when an agent you’ve relied on is captured or a betrayal backfires, the consequences sting in a way that feels earned. The writing and world-building support this beautifully, offering snippets of geopolitical commentary and moral ambiguity that elevate the experience beyond a simple strategy sim. In the end, Sigma Theory: Global Cold War is a fascinating experiment in minimalist strategy design and thematic storytelling. It delivers an experience that is as much about emotion and atmosphere as it is about decision-making. Its focus on espionage and manipulation gives it a unique place among strategy titles, offering a condensed yet memorable portrayal of the invisible wars fought in boardrooms and back alleys rather than on battlefields. While it may lack the depth and longevity of larger strategy franchises, it compensates with personality, tension, and originality. It’s a game that rewards careful thinking and embraces the gray morality of global politics, showing that the pursuit of progress often comes at a human cost. For players drawn to the quiet intensity of strategy, the thrill of secrecy, and the art of deception, Sigma Theory stands out as a sharp, stylish, and intelligent entry in the genre. Rating: 7/10
