Concept[]
Capacity is a an inventory concept introduced at the same time as Multiplayer in 2013. Instead of using slots, the inventory now has a general bag of items that let's a user equip whatever they wish, as long as the total amount carried is less than a limit. Every item carries with it a capacity number, specified in units. These units are not a real world unit, but rather a generalized equivalent of both the size and weight of the item.
