About this game

Environmental Puzzles

  • Use notes, clues, and observations to solve puzzles. Sometimes the answer is right in front of you — and sometimes it’s hidden in the shadows.


About the Game

Underground is a first-person horror adventure where you wake up lost, with no memory of how you got here — and no idea where "home" is. As you explore a strange and seemingly abandoned subway system, you begin to uncover notes, clues, and puzzles that guide you from station to station.

But you're not alone down there.

Survive encounters with terrifying entities that stalk the tunnels. Make decisions that affect your survival, and solve increasingly complex puzzles that block your escape. Each station presents a unique challenge — from tracking down the right medication for a patient under time pressure, to escaping a deadly chase after choosing the wrong item.

Key Features:

  • A story-driven single-player horror experience

  • Multiple underground stations, each with its own set of puzzles, atmosphere, and secrets

  • Checkpoints between stations so progress isn’t lost

  • A mix of stealth, puzzle-solving, and decision-based gameplay

  • Dynamic horror elements that react to your choices

  • Minimal UI for full immersion
