Welcome to Ecco the Dolphin, a classic arcade game originally made for SEGA consoles and now available for Xbox LIVE Arcade. In this game you have to rescue your pod using your powers as a dolphin named Ecco. This game requires 2 playthroughs and there is no way around it. The most important thing in this game is not to die. At best, not even once. Just save and load as much as you want.

Step 1: Playthrough #1

First off, you can find maps of nearly every stage HERE and a complete walkthrough with tips and shortcuts HERE. Now start a new game.

In the very first level, just jump out of the water as high as you can to open the exit to the right. Now you'll find yourself in the Undercaves. Beat it without dying and "Undercaves Survival" will pop up. Remember to pass the Octopus without being hurt and "Octopus Avoider" will unlock, too. Continue to play until you've reached The Vents level. There are 3 dolphins to rescue in order to gain the "Death Sonar" and with that, another achievement. See the guide below for further info on that.

Once you've acquired the Death Sonar, complete the level to reach The Lagoon. At the very beginning, kill 10 sharks (Without killing an enemy of another type inbetween) and after that another 20 enemies of any kind so that "Shark Killer" and "Sonar User" will unlock. There is also another rescue mission in this level to do in order to unlock "Ecco the Hero".

Now continue playing until you've reached the level Ridge Water. If you didn't die once until this point, "Life Saver" will unlock.

The next achievements you can gain are in the stages Island Zone ("Big Blue Message") and Origin Beach ("Songs in the Sea"). You have to find special glyphs on both of the maps, see the guide below how to. Now complete the game and "Game Win 3" should pop up right after the outro - if you didn't die more than 3 times. That's it for the first playthrough.

Step 2: Playthrough #2

At this point, there should only be 2 achievements left to do. now start a new game and play. Don't save the dolphins at The Vents level in order to not gain the Death Sonar. When you've reached the level Dark Water, "Sonar Free" will pop up. Now continue playing until you've beaten the final boss once again and Game Win 2x"will unlock after the outro. 200/200!


Except for the last 3 levels and a few places, this game shouldn't give you much trouble to complete as long as you keep saving your game as often as possible. Remember to make use of the ability to make multiple saves - just in case you find yourself in a sticky situation. Other than that, Ecco requires not much effort.

  • Complete the game 2 times.

    You have to play through the entire game start to finish 2 times. You CANNOT save right before the last boss beat him once load and beat him again, that will not unlock the achievement.

  • Kill 30 enemies with the Death Sonar.

    After you get the Death Sonar form saving the dolphins on The Vents level, kill 30 enemies throughout your game using Death Sonar. Death Sonar is used by pressing then quickly after. That makes your sonar wave act like a bullet.

  • Find the hidden glyph in Origin Beach ("Never have we heard...").

    This one was tricky, you have to swim all the way to the rockwall on the left. Line up with the plants coming out of the water just to the right of the wall. Aim northwest out of the water and let the sonar fly. There are 2 hidden glyphs over there so if you hit the wrong 1 first, keep trying its in there too. In the link below is a map with the approximate location in the rockwall to aim for, the glyph is marked as a WHITE square.

    Like the description says beat the game dying no more then 3 time throughout the game. If your having trouble save often and on multiple saves so if you mess up on one, you can load an earlier save.

    On The Vents level DO NOT save the dolphin's 3 pod members, then make it to the Dark Water level and the achievement will unlock.

  • Find the glyph in Island Zone that tells you to find Big Blue.

    You can find this glyph right about the middle of the map, just after you come acroos a killer whale you can speak with. If your having trouble finding the glyph, the link below has a map with the glyph marked as a WHITE square.
