The Skyforge development team has just announced the date of their second closed beta. The beta which is set to start March 25th has brought about quite a few changes including four new classes, a new dungeon, a new open world zone on Naori Island, and an 8v8 superiority PvP mode.
If you are looking to participate in the beta you will not have to reload their client and your old character should still be intact. This will allow you to continue your progression and play around in the new dungeons, and try out the new classes.
If you are not currently in the beta, then there will be a set of beta invites sent out on March 24th so new players will be able to participate in the beta. For more information on closed beta 2, read the full announcement on the Skyforge website.
