About This Game

Abyssal Trench is a single-player, first-person psychological horror game set deep underwater. You play as a lone explorer who awakens from cryo-sleep after a failed mission. Your escape pod is out of fuel, your team is missing, and a mysterious AI voice directs you to investigate three abandoned drilling sites scattered across the seafloor.

In this narrative-driven horror experience, you must pilot a submersible mech to explore underwater environments, avoid monstrous deep-sea creatures, and survive surreal hallucinations caused by isolation and oxygen deprivation. There are no weapons. Your tools are movement, observation, and problem-solving.

Throughout the game, you’ll collect mission data, uncover story fragments, restore power, and slowly piece together what happened during the lost three years of your cryo-sleep. Each drilling site offers a different challenge, including navigation puzzles, stealth sections, and scripted psychological events.

There is a clear beginning, middle, and end. Most players can expect a focused 1.5 to 2-hour experience on a single playthrough. Replay ability comes from revisiting story clues and events for deeper lore.
