UPDATE: Thank you for your patience, the Registration and Payment systems issues have been resolved.
Dear players,
Some of you may be experiencing temporary technical issues with our registration and payment systems. This is due to a large DDoS attack against a central service provider, affecting many other companies around the world including Nexon America.
We are working internally to mitigate as best as we can to ensure that our games remain online for you. That being said, you might still experience issues. We thank you for your patience. This post will be updated as the situation evolves.
The Nexon Team
