You may have heard about people who have a Glyph Tag as the identifier for their account. This system is under development and has no additional functionality beyond the name yet, but features will be added in the future. You need a Glyph Tag to be able to play Atlas Reactor and if you wish to set one up, you can do so at this link. When you create your Glyph Tag, your tag will be automatically assigned a random 4 digit number that makes your Glyph Tag unique.
The customer service team will be unable to assist in changing this name if you make an error or change your mind regarding your choice of name.
