Multiplayer online battle arena (MOBA) is a genre of strategy video games that originated as a subgenre of real-time strategy in which each player controls a single character in a team to compete with another team of players.
The objective is to destroy the opposing team’s main structure with the assistance of computer-controlled units, which periodically spawn in groups at the base and marching down predefined paths (called “lanes”) toward the enemy base. Every player character typically has its own diverse kit with unique abilities, design, strengths, and weaknesses. Player characters grow in power over the course of a match and learn new thematic abilities, which contribute to a team’s overall strategy. Multiplayer online battle arena games are a fusion of real-time strategy games, role-playing games, and action games, though players usually do not construct either buildings or units.
The genre gained popularity in the 2010s, with Defense of the Ancients mod for Warcraft III, League of Legends, Dota 2, Heroes of the Storm, and Smite being popular. The genre is also well-represented in esports.
