This is a single-player narrative adventure built around cinematic storytelling and branching choices. You play as Chen Anjiu, a former special forces operative. To rescue your target, you must infiltrate the giant ship: observe your surroundings, gather clues, and use items to overcome obstacles — all while concealing your identity through conversations and unexpected incidents, making sound choices and judgments to complete your mission. With over 300 minutes of gameplay, the game features multiple story branches and endings: your choices may alter the fates of its characters, and your decisions may shape the course of the story itself.Officially Licensed by The Three-Body Universe—Experience Operation GuzhengThis game is based on the landmark science-fiction novel The Three-Body Problem. Set on the eve of Operation Guzheng, it casts you as a long-retired special operations veteran boarding the ETO's mysterious cruise ship, Judgment Day. At the same time, in the offices of the Battle Command Center, an extraordinary operation targeting the ship is beginning to take shape...One Ship, Three CreedsAboard this seaborne utopia born of despair and fantasy, you will discover the many faces of the ETO. The Adventists' fanatical vision threatens to reshape humanity's fate. The Redemptionists' extreme faith drives them to sacrifice everything. The Survivors' resignation and compromise are the final struggle of ordinary people fighting to stay alive. Can they reconcile their grand cause with the dangers before them—and how will you navigate the fault lines between them?Gather Clues and Find a Way ThroughNot every threat announces itself with gunfire. Danger may hide in an innocent question or a plan that appears foolproof. Brute force is never your only option: even the smallest clue may give you exactly what you need to turn the tables. Search each scene, seize the right moment, and pay close attention—the answer is often right in front of you.The Consequences Are Unknowable. The Choice Is UnavoidableWhen information comes from an unknown source, choose whether to trust or doubt. When an act of kindness threatens to derail the mission, choose whether to risk yourself or stand aside. When confronted with a cruel and crushing truth, choose whether to reveal it or remain silent. Fate excels at weaving conflict and regret, but it offers no chance to try again. Make choices whose consequences you cannot foresee, then bear the cost. Humanity has no choice but to choose—and humanity can always choose.
