Webzen says that this past weekend's MU Legend stress test was successful and provided enough data about the stability and "endurance" of the server structure. As a result, the game is on track for its open beta release in November.
In addition, Webzen also revealed new Frontier Packs that are available from today through the commencement of the open beta on November 7th. These pack provide players with a number of in-game perks dependent on the level purchased. Packs are available at $19.00, $39.00 and $69.00.
