KeyDrop Upgrader lets you choose an unwanted CS2 skin from the inventory and select a higher-value item you want to receive. The interface shows the selected values and the associated success chance before the upgrade is started.
KeyDrop currently presents Classic, Wheel and Fill modes in the Upgrader interface. The item catalog can be searched and filtered by price and rarity. If there are no skins available to upgrade, the interface directs the account back to case opening.
Items obtained from KeyDrop Cases can be used with the Upgrader when eligible. For direct exchanges rather than chance-based upgrading, see the Skin Changer.
