The third and final entry in the Ratchet and Clank Future trilogy on the PlayStation 3, after Tools of Destruction and Quest for Booty. Dr. Nefarious returns to take control of the Great Clock, a "marvel of science and sorcery" that regulates time throughout the universe, and is located in the exact center of the universe... give or take fifty feet. As in Secret Agent Clank, the duo spends most of the game separated, trying to reunite and stop Nefarious, while they both learn the truth about their respective pasts.
