Ecco the Dolphin — About this game
A violent vortex leaves Ecco alone in Home Bay. His search crosses dangerous seas where swimming skill matters as much as solving the mysteries of crystal glyphs. Sing to sea creatures for clues, hold sonar to inspect the surrounding passages and charge through schools of fish to restore health. Air is a separate concern: surface or find breathing pockets before exploring deeper caves.
