The atmospheric underwater game Echo Deep invites you to guide a submarine through the impenetrable darkness of deep caves. Use the sonic echolocator to briefly highlight invisible rocks, sparkling pearls and safe passages. Remember to be careful, because every sound pulse instantly attracts dangerous deep-sea fish. Drop noisy signal buoys to distract predators, avoid poisonous jellyfish and carefully move through underwater currents to the exit. Improve the characteristics of the bathyscaphe, complete twelve levels and collect valuable game points in Echo Deep.
