Ecco, the bottlenosed star of a nearly forgotten side-scrolling adventure on the retired Sega Megadrive, has made it to the Dreamcast in Ecco the Dolphin: Defender of the Future; this time he's a 3-D dolphin in a hyperrealistic underwater world. You'll control Ecco as he's 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 you can recover the stolen and scattered dolphin power, you'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 puzzles and work with others to accomplish your goals. The game features beautifully detailed seascapes, with creatures and plants that look and move realistically.
