How do I change my username?

To change your username:

Open your profile by clicking on your profile picture.
Once on your profile page, click on the pencil icon.
Change your username and click on the "save changes" button.
Your username can be changed only once! If you want to change it again, go to our in-game store by clicking on its symbol in the main menu.
Click on the modification symbol in the in-game store.
And purchase the "Change Name" feature.
Go back to your profile to change your name. Please note that you don't need to change the name immediately after the "Change Name" purchase.
