Another great game by Insomniac.

Ratchet and Clank are back, and this time, Drekk isn't here to interfer. They are summoned to Mr. Abocrombie Fizzwidget, who is the owner of Megacorp. Your mission is to find and return Megacorp's newest invention, the Protopet. But it is stolen by a thief(who later turns out to be Angela Cross, another Lombax). You go all over the galaxy trying to find her, until she reveals herself on a desert planet. It is then that you learn that the Protopet will destroy the galaxy. So, your new job is trying to get the Protopet back from Megacorp. Easier said than done. You finally meet Mr. Fizzwidget, who turns out to be Captain Quark in disguise. He intends to save the galaxy from the Protopet, but ends up creating a giant, mutated one. After you destroy it, It throws back up Quark, and the Helix-a-morph. Angela uses the Helix-a-morph to restore the protopet to it's normal size. Then you find out that the Mr. Fizzwidget was locked up. This game is another extreamly good game made bu Insomniac. If you have never played it, then you don't know what you're missing.
