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?
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.
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!
"The Gardens" map had multiple breaking bugs. The naming of 2 rooms was completely wrong, found thanks to a community member, thank you! At closer inspection there was also 2 objects placed wrong. The map should now be fixed. My apologizes, the maps are hand crafted and so sometimes mistakes are made.
Read full update on Steam ↗Added some more localization Fixed some localization not showing up in the map creator tool Removed localization prompt from showing when Spanish or English are selected as language Added Spanish as officially supported language Added colors for the different genders
Read full update on Steam ↗Finally fixed a bug with resolution that caused the screen to look dark and pixelated Fixed a bug causing resolution to reset every time you went back to main menu Fixed a bug where the Undo button wouldn't always show the previous state correctly Added full Spanish support for all the maps (Thanks to an awesome community member)
Read full update on Steam ↗We went straight from version 1.07 to 1.09 because the fixes in 1.08 weren't worth mentioning. However version 1.09 is definitely worth mentioning. All 8x8 maps have been properly translated to Spanish! Some main menu localization added Made adding localization easier for the future Fixed a bug where translated room names weren't properly displayed in official maps Special thanks to the community member that is kind enough to help with translation! You know who you are. There is unfortunately still a bug that makes the game look very dark and pixelated when resolution is set to anything other then your windows recommended. Although I think most people run the game in the monitors native resolution I still am determined to get it fixed because I know it's there.
Read full update on Steam ↗Steam achievements changes: Even the Tutorial Hurt My Brain | Instead of having to spend 30 minutes on the Tutorial it is now 15 minutes I Thought About Giving Up, But Then Sobbed Instead | Instead of having to spend 1 hour on an easy puzzle, it is now only 30 minutes General fixes: Saving/Loading should work correctly now Fixed a small duplication bug with a UI element
Read full update on Steam ↗Added a warning prompt on pressing the reset button, so you can't accidentally wipe the puzzle Added more translations Now added the ability to use an undo button. {STEAM_CLAN_IMAGE}/46280077/ee832750839185b6f2503d115ff074c7129de1a7.png I am aware of a bug with changing resolution and there also seems to be an issue with Steam cloud saving/loading but I am not entirely sure, I am currently looking into that.
Read full update on Steam ↗Fixed/Added some translations in: Brewery Controls window Main Menu Small memory optimizations Fixed UI scaling issue Fixed a saving issue Removed some unnecessary files from the build Added a reset button so that you can clear the puzzle completely. Keep in mind the timer won't be reset. {STEAM_CLAN_IMAGE}/46280077/6d3167d2729f1afbcd081c60ac9b495eed2c1fe0.jpg
