About the game

A 3D survival experience set within a cramped one-man submarine exploring a hostile ocean trench.

Original Steam description

Seal The Breach is a tense, atmospheric descent into the unknown.

Trapped inside a failing one-man submarine, you must navigate a deep, lightless trench where something ancient stirs beneath the seafloor.

Manage your vessel’s fragile systems, scavenge what you can from the abyss, and keep the water out - because every breach you seal reveals something far worse.

Cameras flicker. Signals distort. And in the dark zones below, you’ll only catch glimpses of what’s watching you.

Something is down there.

And it knows you’re here.

KEY FEATURES

  • Manage a fully interactive submarine with multiple failing systems

  • Navigate using limited camera feeds and distorted visuals

  • Use a Hydrophone audio device to detect points of interest

  • Survive flooding, power loss, and structural damage

  • Scavenge the ocean floor using a magnetic winch

  • Explore dark zones where reality - and visibility - breaks down

  • Uncover cryptic logs and piece together what happened before you

  • Witness your submarine deteriorate as the water itself begins to change
