As confirmed by the official RF Online site, the MMO is to close in Europe. From the post:
Our licence for RF Online is due to expire shortly and unfortunately, despite several weeks of negotiations with CCR, the Korean developers of the title, we have not been able to reach an agreement to renew the contract.
This means that Codemasters will no longer have the right to operate the service in the Western territories it currently provides service in and therefore we are obliged to shut down all associated game services before the licence expires.
The last full day of service will be 9th November, 2008. All RF Online world servers will shut down on the morning of Monday 10th November, UK time.
More through there. Thanks, Blue.
