About game
Underwater explorers seeking a test of nerves will find Echo of the Depths a perfect challenge for their reflexes. You navigate a research vessel through pitch-black caverns where every movement demands precision and steady hands. The submarine moves forward on its own, so your primary task involves adjusting depth to dodge jagged rocks and treacherous obstacles. Sonar pulses periodically light up the surroundings, showing walls and hidden creatures that vanish almost as quickly as they appear. Balancing your hull integrity against the temptation of rare findings creates a tense rhythm during every run. Gathering research points helps you fill out your Atlas of the Depths while you navigate down to the four-hundred-meter mark. You can escape early with your collected data if the pressure becomes too intense for your ship to handle. Jump into this arcade adventure right now in your browser without any downloads required.
How to play
The submarine moves forward automatically.
On a computer, hold Space or the left mouse button to ascend. Release it to descend. On a phone or tablet, touch and hold the screen to ascend, then release it to descend.
Follow the sonar pulses: they briefly reveal walls, discoveries, and creatures. Adjust your depth in advance and avoid collisions—the submarine’s hull can withstand only a limited amount of damage. Collect glowing samples to earn research points. To study a rare creature, stay close to it until the sonar has scanned it several times.
Descend to a depth of 400 meters, then touch the red evacuation buoy. To end the run early and keep the data you have collected, press Esc or the blue buoy icon, then confirm the evacuation.

- Scientific Progression: Scanning rare creatures adds entries to your personal Atlas, tracking your progress across multiple sessions.
- Early Extraction: Choose to deploy your own buoy to save progress rather than risking a total loss in deeper zones.
