Ecco the Dolphin Walkthrough

3. Story walkthrough

To fully complete Ecco the Dolphin we'll need to go through the game 2 times.

Playthrough #1 Beat the game the easier way: Death Sonar style.
While playing through this playthrough you cannot die until I say you can (which is at level 5: Ridge Water).
The first level will wield you no achievements. Just make sure that you do not die while playing through it. The second level is the Undercaves. You get two achievements at the end of the Undercaves. One for beating the Undercaves without dying and one for doing it without being touched by an Octopus. For the second one, when you get to an Octopus (you’ll know them when you see them) just save immediately and try to get past him without being touched. If you get touched just reload the save.

Finish the Undercaves and you’ll be at The Vents, the third level of the game.

You need to save the dolphin family trapped in this level. This achievement is missable so make sure you save at the start of the level and don't leave until all three dolphins are safe and sound! Killing 30 enemies with the Death Sonar will come naturally, I just decided to insert it here because you unlock death sonar here for saving the family of dolphins.

The next level is The Lagoon and, as soon as you start, go down to see 3 sharks. Kill 10 of them in a row to earn yourself another achievement. They will keep respawning. Also there is another dolphin family to rescue on this level for an achievement.

Have you been staying alive so far? Good, when you reach Ridge Water you will get:

  • Unlocked by 572 tracked gamers (44% - TA Ratio = 1.51) 1,314

After this point you can die but no more than 3 times, so it’s best you just complete the game without dying at all.

When you reach the 11th level of the game (10th if you don’t count the tutorial) you’ll be at Island Zone. You need to find a glyph in this level. Once you find the killer whale, follow the path behind it until the dead end. The glyph is here.

Now wasn't that an easy 50G? Continue until you reach the 15th level (again, 14th if you don’t count the tutorial). This will be Origin Beach. As soon as you start, jump out of the water and aim at the top left corner. There will be a hidden glyph in the cliff, unlocking you another achievement.

Not much left to do now. Keep going and saving as you go. When you reach the final level, save, beat the boss and, if you didn't die more than 3 times (you should've died 0, it’s not hard after all) you get one final achievement for this playthrough.

Playthrough #2. Beating the game one more time

The good news is that you should have a good feel for the game now, and remember the maps somewhat. There are no death restrictions either. The bad news? Well, for this playthrough we cannot use the Death Sonar. When you get to The Vents don’t save the dolphin family. You can still kill the baddies with your normal dash but it’s a little bit harder now. Nothing the save feature can’t handle I’m sure.

When you get to the 22nd level of the game Dark Water (21st not counting the tutorial) you will get the second to last achievement needed in the game.

As for the last one, simply finish the game again.

That’s it for Ecco the Dolphin. I hope you enjoyed the ride and if not, at least you have another completion.
