The signups for the Korean beta that started almost a week ago will be coming to an end soon. The recruitment drive that has already drawn in over 300,000 entrants will end today at 12AM KST (tomorrow at 11AM EST).
16 hours after the registration closes, at 4PM KST (3AM EST), the winners for the beta will be chosen. Following that, from the 18th to the 20th, the winners will be able to play the game between the hours of 6PM KST and 11PM KST on Friday (5AM to 10AM EST) and 4PM KST to 11PM KST on Saturday/Sunday (3AM EST to 10AM EST).
This is only the first of 3 planned Korean beta tests, so if you didn't get in this time you have at least 2 more chances. Remember though that you do require a Korean Social Security Number (KSSN) to sign up for these beta tests.
At this point it's impossible, you'll have to wait till the second beta.
You need an account at dbo.netmarble.net to sign up and you'll need a Korean Social Security Number to create an account. Guides on how to get one can be found on Google.
