Vindictus is a free-to-play action-oriented MMORPG created by devCAT, an internal studio of Korean free-to-play game publisher Nexon. In Vindictus, "classes" and "characters" are one and the same. When beginning the game, players will have a choice to play as one of ten 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 ten. Vindictus is particularly combat-intensive when compared to many other Action MMORPGs. The combat is very fast-paced and rewarding; it uses more combo-based combat than timing of activate-able skills (or 'Active's as labeled in-game on the skill chart). The combat is very rewarding because of its dodge/counter/block or die mentality while in combat as opposed to the typical 'out dps the boss' mentality.
