Ecco's peaceful home changes when a violent disturbance carries away the other dolphins. Finding them means exploring an ocean that grows increasingly strange, using sonar to communicate and investigate the world. Swimming has expressive momentum, allowing swift turns and spectacular leaps, but movement is never entirely carefree.
Ecco needs air, and narrow passages can make the route back to the surface as important as the route forward. Environmental puzzles and hostile creatures demand observation alongside dexterity. Its beauty carries an unsettling edge: the deeper the search goes, the less the sea resembles a safe, familiar place to return to.
