Travel through time along with Ecco the Dolphin , in a game that lets you control a dolphin as it goes about its natural behaviors. You can eat fish, surface to breathe, use your biological sonar to navigate, and jump out of the water for fun.
The storyline is more complex than it initially seems. As Ecco, you're the only dolphin who escaped a giant whirlpool that swallowed your pod. The five shining stars on your forehead mark you as the chosen one to save them. However, this task won't be easy, as you'll need to travel through time and space using the Atlantean time machine, meet the mystical Asterite, and defeat the Vortex Queen.
The main gameplay in Ecco the Dolphin involves exploring various aquatic levels that are usually non-linear. You'll navigate through submerged caverns and tunnels with obstacles like islands to hop over, volcanoes spitting hot lava, strong currents, deadly spikes, and predators like octopi and giant eels. The sonar ability serves multiple purposes: it lets you communicate with friendly animals, map out your surroundings, activate glyphs, and defeat enemies.
Keep an eye on Ecco's life and breath meters. Dolphins can't stay underwater for too long and need to surface for air. However, some caverns may have hidden pockets of air. Every time Ecco takes damage from spikes, lava, or enemies, its health will decrease, and if it reaches zero, you'll have to replay the level from the start. The life meter can be replenished by eating fish or finding healing clams called Shelled Ones.
