Ecco, the bottlenose star of a nearly forgotten side-scrolling adventure on the retired Sega Genesis, has made it to the Dreamcast in Ecco the Dolphin: Defender of the Future, and this time he's a 3-D dolphin in a hyperrealistic underwater world. Players will control Ecco as he is sent back into the past and tries to reinstate the paradise of his future. How? Evil forces have conspired to destroy the planet, and if Ecco can recover the stolen and scattered dolphin power, he'll be able to restore the harmony between dolphins and humans.
But there'll be time for that. First, you're going to have to learn to swim, eat, and think like a dolphin. Use different songs to communicate with other sea creatures and be prepared to defend yourself against predatory sharks. Later, go on to solve puzzle
