Vindictus

Vindictus is a MMORPG (massively multiplayer online role-playing game) created by devCAT, an internal studio of Korean free-to-play game publisher Nexon. Vindictus is a prequel to the popular MMORPG Mabinogi and is known as Mabinogi Heroes (Korean: 마비노기 영웅전) in Asia.
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.
