According to a new post from NCSoft on the Lineage site, the North American game servers will be closing permanently on June 29, 2011. NCSoft indicates that the 'franchise is no longer profitable', hence the server closure.
As of today, no new accounts can be created. We will no longer charge anyone whose account is set to recurring billing, and Time Cards can no longer be used to add additional game time. We have reactivated all existing accounts in good standing, and everyone can play for free* for the remaining time that the servers are open.
We are committed to refunding any unused game time that might have already been applied to your account. If you are due a refund, refunds will be made automatically back to the method of payment that was originally used in most cases. Please see our refund policy for details.
Nyx, Jetzen, and Unicycle plan to go out with a bang. We will not be making any additional content updates, but we do have US Ruleset changes and lots of great events planned for the next two months. We want to give you every opportunity to make all of your remaining Lineage dreams come true. We hope that everyone will stick around to have fun with the game you love in the time we have left.
