A storm rips Ecco's pod out of the sea in the opening minutes of this 1992 Genesis game, and the young bottlenose dolphin sets off alone to learn why. Designed by Ed Annunziata and developed by the Hungarian studio Novotrade for Sega, Ecco the Dolphin turns that simple premise into a lonely, puzzling journey that reaches ancient Atlantis, the distant past and eventually an alien threat known as the Vortex.
There is little combat in the usual sense. Ecco rams sharks and jellyfish, uses sonar to talk to other sea creatures and read glyph crystals, and must surface regularly for air, which turns underwater caves into tense races against the breath meter. The sonar doubles as a map when its echo returns. The game became famous for its difficulty and its eerie atmosphere, and its ambient soundtrack and unusual subject matter made it one of the most distinctive Genesis releases. A Sega CD edition added extra levels and a new score.
Tips for Ecco the Dolphin
Hold the sonar button to send out an echolocation pulse that returns a map of the surrounding area.
Watch the air meter and plan routes past air pockets before entering long tunnels.
Sing to glyph crystals and other creatures; many of them hold the clues needed to progress.
