ArcheAge Korea has been running for a couple of months now, and I just saw a really awesome fan-made video produced by the guild, apparently known as The Black Storm Empire. Enjoy!
There is also a promotion going on now between developer XLGAMES and Korean fast food chain, BBQ Chicken. Similar to most, purchase some food, and get an exclusive chicken hat costume as seen in the picture below.
There is also an update for the English server of ArcheAge, handled by Trion Worlds. Head on to the ArcheAge Source forums for a detailed read, including the progress and expected duration for Closed Beta!
