Vindictus (Korean: 마비노기 영웅전, Mabinogi Heroes) is a "hack and slash" 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 outside of North America and Europe.

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. Nexon America, Nexon's North American division, announced the new name on March 12, 2010 at the Game Developers' Conference in San Francisco.

Vindictus follows Nexon's traditional free-to-play model. The game itself will be free to download and play and charged no purchase price. The game will contain a virtual item shop to purchase in-game items through Nexon points to enhance the player's character's appearance, abilities or to revive a player.

The name was changed from Mabinogi Heroes to Vindictus. Vindictus is said to be derived from two words: Vindicate (maintain, uphold, or defend, OR clear of accusation, blame, suspicion, or doubt with supporting proof) and Vindictive (having or showing a strong or unreasoning desire for revenge).

Vindictus uses the Source engine to allow players to interact extensively with the environment. Environmental objects can be destroyed or picked up and wielded as weapons. Combat is described as "kind of brutal, like a bullfight, or Monster Hunter" and will vindictus gold require a lot of teamwork.

Vindictus' "Classes" and "characters" are one and the same. When beginning the game, players have a choice to play as one of five characters (only three currently available), 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. They are gender-locked.
