Fans of Black Desert who are looking for all that they can discover about the forthcoming game, will want to check out Steparu.com's beta preview featuring a look at at both PvP and GvG. Black Desert is currently in beta testing in Korea.
For beta testing purposes the GvG session lasted for three hours long. During this time, the first Guild to take over the castle wins. How does a guild take over a castle? Right when the event started, all the guilds started attacking each other outside the safety zone in town and on the way to the castle, it was very hectic. After reaching the castle, your guild must break down the first door. Then destroy the 2nd inner door within the castle. Once those two doors are down, you just charge in and rush the statue that has a ton of HP. The first guild that destroys the statue will obtain the castle. After a guild succesfully takes over the castle, other players that are not in that guild or alliance will automatically get kicked out of the castle instantly spawning them in town. The castle doors will respawn and from here on out, they will have to defend until the event time is over.
