You're Jak, a quiet hero in the making. Jak and sidekick Daxter are playing on Misty Island a wee bit close to a pit of Dark Eco. Daxter falls in and crawls out looking like a fused otter and weasel. The two visit the village's local wise man, the Green Sage, to transform him back. But the Magical Ports from one island to the other have shut down, and the only way to reach the more knowledgeable wise men that could help him is to embark on an adventure, of course. In every region there is a strange conspiracy around the concept of Eco that adds another layer to the game. Dark Eco is deadly, or at the very least, mystical and strange. Jak and Daxter's world is filled with all kinds of the mysterious element known as Eco. Green Eco gives life, and it's contained in chests and containers all across the many environments the pair encounters. Blue Eco provides energy, speed and opens doors, and Red and Yellow Eco provide energy and the ability to cast fireballs, too. Races, a collection of minigames, enemy chases and timed events are all part of the gameplay.
