Square Enix's new Final Fantasy XI Test Server has officially launched! As a means to allow players to engage in testing new content before it is released, and in turn allowing for new content to be released much sooner for the game, applications for those interested in participating are currently being accepted. There are only limited spots available per testing session, so if you meet the required criteria and want to do your part in this new FFXI endeavor, be sure to submit your application as soon as possible!
