The followup to Ecco: The Dolphin , in which Ecco successfully destroyed the Vortex. Unfortunately, it turns out that the Vortex Queen followed it to the Earth and eventually destroyed the Asterite. All the world's oceans are threatened, and actually already doomed.
In order to restore the Asterite and finally defeat the Vortex Queen, Ecco will have to confront once again the tides of time, which have split into two possible futures, the regular one and the dark one dominated by the Vortex Queen.
Ecco: The Tides of Time features even better graphics than its predecessor, and introduces a new gameplay mode in which the camera follows the dolphin from behind instead of from the side. Gameplay involves exploration, puzzle-solving, and combat against various enemies as Ecco navigates through different environments to reach his ultimate goal.
The game takes place across various oceanic environments, including coral reefs, shipwrecks, and underwater ruins, all filled with hidden secrets and paths to discover.
