Upgrading a system involves replacing conventional components with technologically enhanced versions, resulting in a system that has the same size and weight as the original, but possesses superior functionality.
Upgrading costs 10x the standard system price. All systems except weapons, armor, and perhaps flares are upgradeable.
Factory Interface Changes:
As it is now, when you install an engine, for example, the "Engine" link changes to "Remove Engine". This could be changed so that it becomes "Modify Engine" instead, and when you clicked on it, a page is presented asking you if you want to Upgrade or Remove the engine. This page is similar to the one that comes up when you are asked how much ammo you want to install with a gun.
Upgraded systems are denoted by a trailing +, so an upgraded Krios K5 becomes a Krios K5+. Money can be difficult to amass in TOS, so a titan that has even one of these upgrades would be a valued asset.
