MapleStory 2, welcome.

Pretty straight forward sign-up process. Click on the big CBT button on the front page





Then click on this button





If you have a Nexon account and are logged out it should have asked you to log in by now.


Next is a window I didn't capture. It has 2 buttons, a left and a right.
Left = Apply with a Nexon account
Right = Apply with your cell phone


Click the left option
Click next on the "Nexon Play" window with the QR code
Done


If you see this message pop up on your screen after you apply





That means you've already applied and are now waiting for the drawing.
