In 3079, you are able to upgrade weapons, armour and anti-gravity packs using varies modules, however, upgradeable items are only able to support one single module and the module cannot be removed after the upgrade is completed.
(Not having sufficient engineering skill can result in an electric shock or even the module breaking! The more engineering skill you have the more likely it is that the installation of a component will be a successful.)
Items that are upgraded have "Customized" in the title and always fetch a higher price than the item prior to being upgraded.
Note: Items that give stat bonuses must be equipped for the bonuses to be applied to Player.
