Gun, Bouncer and Lava Gun. Each weapon has a "growth bar", which increases when the weapon is used to defeat enemies. The weapon is upgraded once the bar is filled, increasing its power and changing the design of it. Certain devices from the original Ratchet & Clank make a return, such as the Swingshot, while others are new to Going Commando. The player can use a save file from the original Ratchet & Clank to get "retro" weapons from the first game for free, although these weapons do not upgrade. As with weapons, Ratchet gains experience with each enemy he defeats. When Ratchet's experience bar fills, he gains a new level of "nanotech." This awards him with additional health bubbles, up to a maximum of 80 can be obtained. Ratchet's health can also be increased by finding nanotech upgrades. The game introduces armor vendors, which are able to provide up to four additional levels of protection. Plot After saving the Solana galaxy from the menace of Chairman Drek, Ratchet (James Arnold Taylor) and Clank (David Kaye) become celebrities, though their lives remain otherwise uneventful. After giving an interview for the holovision show Behind the Hero, the pair suddenly find themselves teleported into a spaceship sent by Abercrombie Fizzwidget (Jim Ward), the founder and CEO of MegaCorp, the Bogon galaxy's largest maker of consumer goods and electronics, who requests Ratchet's help to recover a stolen biological experiment from a masked thief, while offering Clank employment in the company, both of whom agree to the opportunities offered. Upon completing an extensive training regime en route to the galaxy, Ratchet is tasked with travelling to a flying laboratory on planet Aranos where the experiment was last seen, but before he can retrieve it, the thief manages to escape with it. Reporting back to Fizzwidget, Ratchet soon begins pursuing the thief, only to receive a video message showing that the culprit has captured Clank in an attempt to deter Ratchet from his mission. After saving Clank from the thief's clutches, the reunited duo work together to pursue the thief across several planets, dealing with mercenaries hired from Thugs-4-Less to protect the thief, leading to a confrontation on planet Siberius. Although the thief escapes from them after a fight, Ratchet and Clank secure the experiment, and arrange a meeting with Fizzwidget so that he can reclaim it. During the handover, Fizzwidget "accidentally" maroons the duo
