KingPS3.com: "Starting off with Ratchet & Clank Future: Tools of Destruction, the PS3 Ratchet & Clank series has gathered a fair amount of fans. Tools of Destruction brought new and unique weapons and gameplay aspects to the table (which isn't very surprising with it being a Ratchet & Clank game) which was followed by Ratchet and Clank Future: A Quest for Booty, a PSN downloadable title that further progressed the series' story. And now comes Ratchet's next adventure, A Crack in Time.
Before the game even begins, you'll have the chance to listen through an interview with Captain Qwark which will help the Ratchet and Clank newbies become familiar with the title's story. You'll then continue your search for Clank, who went missing in Tools of Destruction and was searched for in A Quest for Booty without success. The game soon tells you that Clank was kidnapped by the mysterious Zoni and taken to the evil Dr. Nefarious. It is now your job to save Clank and defeat anyone who stands in your way."
