Deep Line

Deep Line is a single-player, first-person survival horror game set in an abandoned underground subway. Following a rumor that gold is hidden there, you search for gold and key items, then try to escape while something hunts you.

Survive the underground

The pursuer is an AI-controlled monster that reacts dynamically to sound and movement. Sound can attract it, so you need to stay quiet and move carefully. You can run, hide or fight back, though opportunities to resist are rare.

Find a way out

You manage your resources, collect gold and uncover escape routes. Several ways to escape are available, each with its own requirements and obstacles, and your decisions shape the route you take.
