The full form of MOBA is Multiplayer Online Battle Arena.
MOBA is a subgenre of strategy video games where two teams compete against each other on a predefined battlefield. Players control a single character ("hero" or "champion") with unique abilities and work together to destroy the opposing team's main structure. These games typically involve elements of real-time strategy (RTS), role-playing games (RPGs), and team-based gameplay. Popular examples of MOBA games include League of Legends, Dota 2, and Heroes of the Storm.
