Ratchet & Clank Future: Tools of Destruction

Excerpt from [wikipedia]:

“In the midst of working on a hoverbike on the planet Kerwan in Metropolis, Ratchet and Clank receive a desperate call for help from Captain Qwark, which they respond to. They find that a large army of robotic commandos have laid a full-scale assault on the capital city, led by Emperor Tachyon, crown prince of the Cragmites. Tachyon reveals that he is after Ratchet, the last Lombax in the galaxy; outnumbered and overpowered, Ratchet and Clank flee. The two decide they must learn more about Tachyon and begin to search the Polaris galaxy for answers. During their investigation, Clank is visited by small robots called the Zoni that only he can see; the Zoni upgrade Clank and tell him that he is special, and that he must help Ratchet make a difficult choice in their current adventure. The duo also acquire the aid of Talwyn Apogee, the daughter of Max Apogee, a famous explorer who collected artifacts from the Lombax culture before he mysteriously disappeared.”
