When your father disappears without a trace, your mission is to venture into this mansion in the middle of nowhere to uncover the mysteries it hides. But be careful, you are not alone.
Datagames Studios presents an experience in which sound is your greatest—and only—ally.
In Lost Files: 1978, you find yourself alone in the face of danger.
Without sight, you move forward in complete vulnerability, so you must make sounds (gunshots, footsteps, throwing objects) or interact with your surroundings.
Each pulse momentarily reveals walls, objects, and hidden presences through sound waves... but there is a price: every noise also gives you away.
Inspired by survival horror classics such as Resident Evil, your goal is to escape by solving puzzles and exploring the mansion while a presence relentlessly stalks you. Use the tools to your advantage, stay out of sight, find hiding places when danger approaches, and shoot only when necessary.
Delve into the mansion and search for traces of your father: gather hidden clues, examine every corner, and solve environmental puzzles to unlock new paths to the truth.
In 1978, the story is not told through cutscenes or long texts: it is embedded in the mansion. Every room, object, and riddle is part of the narrative. Explore, connect clues, and solve the associated puzzles: each player can reconstruct, at their own pace, the truth hidden in Estancia Santa Rosa.
Datagames Studios was born as a way to express our ideas in video game format, exploring experimental proposals and unusual combinations. This is our first commercial project and marks the beginning of an anthology of experiences under the name “Lost Files,” where each installment tackles a new case, a new place... and a new truth to be discovered.
