Every player has access two free character rotations, one for Lumia Island and one for Cobalt Protocol (characters who are part of these rotations are highlighted with a green and blue open lock icons respectively). The set of characters available change on Wednesday each week.
To unlock characters permanently, players must use 
A-Coins, a currency earned by playing the game. Another options is to unlock characters with 
NP, the game's cash currency, or 
Event NP (obtained from promotions and events). Different characters have different costs. The latest character release always has an increased A-Coins cost of 9,900 for the first 2 weeks. Using Character Voucher (Beginner) will let the player select one of these characters for free: Aya, Magnus, Hyunwoo, Lenox, Luke, Leon, Eleven, Vanya, Alonso, Kenneth, Katja, Charlotte, Darko or Garnet.
Players can also earn Yuki, Hyejin and Eva for free by completing the Basic Tutorial course (any characters already owned will refund their full A-Coins cost instead). It is worth mentioning that redeeming cosmetic skin codes from promotions and giveaways for unowned characters will also unlock the character they belong to for free (Purchasing skins for unowned characters won't unlock the character they belong to).
New character releases are always banned from Ranked matches for a week to give players time to familiarize themselves with them, and in case there are any unforeseen problems or exploits that may affect ranked in a negative way.
