Vindictus takes place in the same setting used in Mabinogi, but is placed chronologically several hundred years prior to the first game, during a period of war and strife. Vindictus follows Nexon's traditional free-to-play model. The game itself is free to download and play and charges no purchase price. The game contains a virtual item shop to purchase in-game items with Nexon's virtual currency called NX (or Karma Koin) to enhance the player's character's appearance and abilities.There are also outside markets of the game, that sells gold and other items to players.
In Vindictus, "classes" and "characters" are one and the same. When beginning the game, players will have a choice to play as one of sixteen characters, each of which has different combat skills and abilities. Players are free to alter certain aspects of their character's appearance, but basic abilities and combat styles are set at character creation. All characters are gender-locked. Though the game was originally intended to have five characters, there are now currently sixteen.
