Ratchet’s desperate search for Clank resumes with a bang as he finds himself engulfed in ship-board combat — only to be cast adrift and washed up on the shores of a remote island on the planet Merdegraw. Our Lombax hero must overcome life-threatening challenges, encounter hostile new alien races and even form an allegiance with dreaded Captain Slag’s first mate, Rusty Pete. All in the pursuit of clues that lead Ratchet to the treasure of Captain Angstrom Darkwater, Slag’s former commander and keeper of the only known link to the mysterious Zoni: the Fulcrum Star.
