Ecco the Dolphin

Ecco the Dolphin is an adventure game released for the Sega Game Gear, Sega Master System, and Sega Genesis involving the adventures of a young dolphin named Ecco the Dolphin. His characteristic feature is the stars on his head arranged in a unique pattern.

Plot
One day, Ecco was challenged by a member of his pod to see how high he could jump.

Upon accomplishing this feat, a water spout occurred and blew his entire pod away into the sky.

Ecco, now alone, sets off to search for his pod...

Gameplay
Ecco as a dolphin is able to swim, jump and use echolocation, from which he gets his name.

Using echolocation will have him send out waves which when bounced back will bring up a map of the surrounding area telling Ecco of the dangers or rewards ahead. The echolocation can also be used to talk to other dolphins and whales and later upgraded into a sonar attack that will temporarily stun enemies.

Ecco's main attack is his dash which allows him to dive towards an enemy, ramming them with his bottle nose.

Being that he is a mammal, Ecco must occasionally surface to breathe. He has both a health bar and an oxygen meter. If the player does not get Ecco to the surface or to an airpocket to allow Ecco to recover his oxygen meter his health bar will begin to drain as Ecco starts to drown. Ecco can also recover oxygen from certain clam shells that release oxygen when echolocated, but beware these clam shells can also spit out filthy water bubbles that actively hurt Ecco instead.

Health can be recovered by dashing into a school of fish, which Ecco will eat.

Along the way Ecco will come across other dolphins who have also lost their pods. If Ecco can rescue their members he will recieve a useful permenant upgrade to his skillset for the rest of the journey.

Japanese version differences
There is an extra level named "The Stomach" which takes place after the final boss. It uses artwork not found elsewhere in the game, and the sonar does not display correctly. This level only appears in the Japanese Mega Drive version. It is speculated that this was an unfinished concept level that was accidentally left in the game. All data associated with this level was removed in all other versions.

After beating this stage, the ending plays as normal.

Welcome to the Machine also has three checkpoints in the Japanese version.

Game Gear
The Game Gear version features the name "Sega" done like a dolphin cry as the logo is shown at the start, and dolphins laughing at the title screen.

Sequels
