The MU Online team is encouraging guilds to step up recruitment to win in-game prizes. Beginning tomorrow and wrapping up on May 6th, players are encouraged to create guilds, recruit members and reach milestone levels and / or character class requirements before submitting the information to the devs.
Once meeting the requirements, guild masters will receive in-game swag, with guild members also scoring cool wings. A pair of random guilds will also be drawn for more prizes.
Check out the "United We Stand, Divided We Fall" information on the MU Online page.
