the city's rightful heir, The Kid. Meeting with the Shadow's lieutenant, Torn, the pair learn that Praxis is seeking to protect the city from creatures known as Metal Heads, an evil biomechanical race dating back from Precursor times. Working for the Underground, the pair eventually discover that they have been flung nearly 500 years into the future, after finding the remains of their home village in the city's borders. To further complicate the matter, the pair also learn that the Shadow is none other than Samos—albeit, a younger version, unaware of the ruins significance. Learning that Praxis is seeking an item within a tomb of the city's founder, Jak and Daxter continue working for the Underground, along the way taking work for the crime lord Krew, and reuniting with Kiera, who works as a mechanic in the city's arena.

Working with Young Samos, the pair eventually help the Underground access the tomb, but become separated when it closes shut on them.

Seeking to rescue the Underground, after its chief members were kidnapped in their absence, Jak and Daxter reunite with the older version of Samos, who warns the group that The Kid must be found urgently, despite Young Samos contradicting his instructions. However, Jak and Daxter soon find they must, after preventing Praxis from completing his bomb with the assistance of Krew, whom the pair kill. Shortly after Krew's death, Metal Heads swarm into the city, forcing the Underground and Krimzon Guard to join forces to resist the invasion.

Departing to complete a ritual he had been working, Kor kills Praxis, who entrusts the Precursor Stone to Jak and Daxter. The pair swiftly pursue
