Zen's Inventory System aka ZIS contains an extensive selection of and that can be purchased, wielded and equipped. Most weapons and armor available to players are manufactured by one of four companies: BlasTech, CDMC, Merr-Sonn, SoroSuub. The weapons and armor manufactured by these companies are then able to be ordered by player-run businesses with the aid of a vendor terminal. Once ordered, the proprietors of the vendor may sell the goods to other players. In addition there are two NPC weapons dealers.
