Echo Abyss
About this game
A deep-sea exploration game built around sonar. There is no light around you—only the spacebar or left click can send out a sonar pulse, briefly tracing the path ahead. But every sound also gives away your position. Keep descending, collect relics, and manage your hull, pulse energy, and decoys as you evade the threats of the abyss in a tense atmosphere. The interface shows depth, objectives, and status cues, while procedural audio reinforces the feeling of echo.
