So right now Closers online is officially starting their second CBT. The whole process starts around June 2nd and ends around june 21st.
Right now the biggest issue is having a KR cell phone number for beta registration. Unless you have a Kr phone or know someone with a KR phone, it will be pretty difficult to get into.
I am working on that process as we speak, so hopefully I can get in and then I will give you more information on the matter.
