Ratchet & Clank Future: Tools of Destruction (titled Ratchet & Clank: Tools of Destruction in most PAL regions) is a platform game developed by Insomniac Games, released on October 23, 2007 in North America and on November 9, 2007 in Europe. It is the 7th installment (although it was the sixth to be released) in the official Ratchet & Clank canon and the first PlayStation 3 installment as well as the first installment for the "Future" trilogy. It was also one of the first PlayStation 3 games to support DualShock 3 rumble straight from the disc.
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 Pervival Tachyon, crown prince of the Cragmites. Ratchet laughs at Tachyon because of his first name Percival. Tachyon reveals that he is after Ratchet, the last Lombax in the galaxy and wants to kill him because he is driven by hate for the Lombaxs; 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.
As they travel from planet to planet, they learn from allies that during the Great War long ago, the Lombaxes had wiped out all of the Cragmites, and were considered heroes of the universe. Exactly how the Lombaxes had done so, however, was unknown, and that had become known as the Lombax Secret. Ratchet learns of the abandoned home planet of the Lombaxes, Planet Fastoon, and goes there to learn of the Lombax Secret, revealed to be the "Dimensionator", a helmet that is able to open wormholes to other dimensions. The Lombax had used it to banish all the Cragmites to an alternate dimension, except for one; Tachyon was found as an egg after the Great War, and was raised by the Lombaxes as revealed by the Iris supercomputer that was on the same planet Tachyon was on; after learning what the Lombaxes had done to his species, he launched an all-out attack on Fastoon. The Lombaxes realized that the best solution was to send themselves to another dimension with the Dimensionator, attempting to fool Tachyon that he had destroyed the race, though two were left behind: the Guardian of the Dimensionator and his son. Tachyon reveals that he ended up killing the Guardian but not before he could send his son to the Solana galaxy, and that Ratchet is that son.
Recognizing that Tachyon plans to use the Dimensionator to bring back the Cragmites from banishment, Ratchet and Clank recover it first, but Captain Qwark shows up and tries to destroy it himself; the blunder allows Tachyon to recover the device. As the duo confront Tachyon with his assembled army on Fastoon, which Tachyon plans to remake as the new Cragmite homeworld, Tachyon tempts Ratchet by opening a wormhole to the dimension where the Lombaxes now live, but, with help from Clank's advice based on the Zonis' warnings, Ratchet recognizes he must stop Tachyon completely, or else the Cragmites will not only control this dimension but also the Lombax's dimension. Ratchet and Clank fight Tachyon, and are able to get the better of him. The Dimensionator is damaged during the battle, opening a black hole that Tachyon falls into, and while Ratchet and Clank are able to flee with the use of a 33⁄4 cubits hexagonal washer given to them by the plumber, the device becomes irreparable.
As Ratchet and Clank and their allies gather to celebrate the victory, the Zoni show up, now visible to everyone. The robots tell Clank that it is time to come with them and that they are now going to bring him "home", to show him "who he is" and "what he'll become". Clank "willingly" goes with them despite Ratchet's protests; the game ends with the disappearance of Clank and the Zoni, with Ratchet stunned and helpless to stop them. The quest to find where Clank disappeared to continues in Ratchet & Clank Future: Quest for Booty.
