On September 3, Webzen launched a pre-event ahead of an upcoming combat balance improvement update for its PC MMORPG 'MU Online'.

Following renewals that enhanced traits for five classes in the first half of the year, Webzen plans to adjust the combat balance for four classes in the second half. Players can focus on leveling these four target classes on the upcoming Speed Server.

The pre-event runs through September 17. During this period, players can participate in Speed Server pre-registration as well as a free Seed Sphere mounting and removal event. Speed Servers are dedicated servers offering growth-support benefits to help level new characters rapidly.

Pre-registered players will receive a time-limited Bloodangel Main Weapon Box and a full armor set. Characters leveled on the Speed Server can be transferred to the main servers for free at a later date, with additional rewards provided based on progression milestones.
