RF Online announced that from now on, it will actually be harder for players to engage in microtransactions, in order to prevent fraudulent credit purchases.
Any RF Online or ArchLord player who wishes to make micro-transaction purchases should login to their Codemasters Online Player Account page where they will see a new button on their subscription line which will allow them to request approval from Codemasters to make these purchases. It is important that when you make this application you ensure your personal details are correct for our records. If you need to update your details you will be presented with a form to edit them.
