The bottom screen contained weapon icons for either the weapon or ammo to be purchased. The top screen contains a scrolling message describing the product (or gags if left idle). When activating the vendor, the segmented pieces of the vendor will separate out to form the menu screens. Each vendor has a large black "G", in fact a hologram, denoting their location, with the word "Gadgetron" revolving around. They appear as a segmented blue cube, with four antenna jutting out from each side's center. (purchased from the Shady Salesman on Rilgar), the Suck Cannon (obtained on Eudora after " Explore the mills"), the Morph-o-Ray (obtained on Oltanis after " Search the destroyed city"), and the gold weapons. The exceptions are the Bomb Glove (it being already owned by Ratchet), the R.Y.N.O.
The blue Gadgetron vendors sell most weapons in the game. Other characters also sell various gadgets and items, but the most relevant is the Persuader from " Bring raritanium to inventor", a black market device that lowers the price of Gadgetron weapons. Similarly the Gadgetron PDA is sold by ' Steve McQwark' in " Purchase Gadgetron PDA from 'Steve'". Technically not a vendor, the Shady Salesman does sell the unique R.Y.N.O. The other vendor is the so-called 'gold weapons room', a secret room where gold weapons can be purchased, more powerful versions of a select group of ten total, that require gold bolts alongside a large sum of normal bolts. They are available at essentially any location ever visited, updating their stock as you progress through the game. These sell weapons and ammunition, the latter of which is also done by the Gadgetron Personal Delivery Assistant, albeit at an inflated price. In the Solana Galaxy the most common are the segmented blue cubes, owned and operated by Gadgetron Corporation. Ratchet & Clank features two types of vendors.
