About Fatal Logic
Welcome to Fatal Logic, a deductive puzzle game where logic is your only weapon against a mounting body count. If you love unraveling mysteries, piecing together clues, and playing detective, prepare to test your mind to the absolute limit. What started simply as a fan project that got way out of hand has evolved into a full experience. This game is heavily inspired by the brilliant Murdoku books by Manuel Garand (though not officially affiliated with him). We strongly encourage you to check out his books for more incredible puzzles! Every level presents a chilling crime scene and a handful of suspects. Using grid-based deduction, clues, and process of elimination, you must sift through the evidence to uncover the undeniable truth: Who is the killer? Key Features Deduction Meets Murder Mystery: Use pure logic, cross-reference clues, and solve intricate whodunit scenarios where every clue brings you closer to the culprit. Growing Puzzle Library: Tackle a collection of 20+ handcrafted logic puzzles (and growing!) that offer hours of challenging gameplay and brain-teasing investigations. In-Game Puzzle Creator: Put your own devious mind to the test! Design custom crime scenes, set up clues, and craft unique logic puzzles using the built-in creator. Steam Workshop Support: Share your darkest mysteries with the world! Upload your custom creations to the Steam Workshop and download an endless stream of fresh puzzles built by other players. Planned Features The investigation doesn't stop here! Here is a sneak peek at what is currently planned for the future: Expanded Campaign Mode: A deeper narrative-driven journey through even more twisted crime scenes. Performance-Based Ranking System: Test your detective efficiency and earn ranks based on how quickly and cleanly you solve each puzzle. Localization: Adding support for multiple languages so detectives worldwide can join the case. Co-Op Mode (In Exploration): We are looking into ways for two detectives to team up and crack cases together in a future update. Can you crack the case, or will the killer walk free? Put your detective skills to the test in Fatal Logic!Read more
