Plot A year after the Dark Maker ship has been destroyed, Haven City has been steadily rebuilt after Errol's defeat, and has grown into a peaceful utopia. Kras City, a dangerous dystopian city full of ruthless mobsters, is also home to a popular sport known as "Combat Racing". Jak, Daxter, Ashelin, Samos, Keira and Torn are invited to the reading of Krew's (one of the villains of Jak II) last will, where they meet Krew's daughter, Rayn. After offering a toast, Krew reveals in a recording that he always wanted to win the Combat Racing Championship and demands that everyone present drive for him, revealing that the wine they toasted with was poisoned with minute doses of a slow acting poison known as Black Shade.

Divided into four cups, Jak and his friends must race and win each round of the race to gain entrance to the championship.
