Depths of Sanity is an underwater exploration action game in which players pilot a submarine into the dark depths of the ocean after a mission goes wrong. Exploring interconnected areas, upgrading the vessel, and battling hostile sea creatures drive the journey deeper.

Its murky, claustrophobic atmosphere and growing sense of unease give the exploration a tense, mysterious tone. Fans of exploration-focused action games with an eerie deep-sea setting will find its premise engaging.
