This follow-up to Ratchet & Clank Future: Tools of Destruction sees the duo trying to reunite with each other after Clank is captured by the evil Dr. Nefarious. The space adventure is one of the best in the Ratchet and Clank series, with challenging puzzles, vivid graphics, and crazy weapons, and the game finally answers some of the questions (like the characters' origins) that gamers have been curious about.
