It differs from from a Gadgetron vendor in several key areas: it is not shaped like a box, has a floating "M" as opposed to a "G," and sells MegaCorp weapons (although one can purchase ammo for Gadgetron weapons. The MegaCorp Vendor is similar to Gadgetron vendors (from Ratchet & Clank) in one regard however, you must manually buy every weapons ammo individually rather than refill all guns with one purchase. Additionally, it also features a ticker with messages from MegaCorp, similar to Gadgetron vendors during the Blarg crisis.
