About the game

Thalassophobia is a 4-player co-op horror diving game set in the crushing darkness of the deep ocean. Complete high-risk objectives and uncover long-forgotten secrets. The further you descend, the less safe you are.

Original Steam description

Team up in Thalassophobia, a 4-player co-op horror game where you descend into the ocean's depths to uncover sunken secrets and survive the terrors lurking below.

Dive into the ocean with up to 4 players in this co-op horror experience. Work as a team to explore, complete objectives, and stay alive in the abyss.

Equip yourself with a variety of gadgets to light your way, locate mission objects, and overcome the challenges of the deep.

Experience breathtaking visuals and chilling audio as you venture into the unknown. Every dive will bring you face-to-face with the nightmares hiding in the shadows.

Use immersive voice chat to coordinate with your team, but beware—the horrors of the deep will test your nerves and your ability to keep it together.
