Dota 2 is a strategic multiplayer online battle arena (MOBA) game based on the original Defense of the Ancients title. In Dota 2, players control characters known as "heroes" and are pitted against an opposing team in battles that take place in a fantasy setting. The game features all the same characters and factions from the original Defense of the Ancients, but with added features such as improved graphics, new maps, and more detailed hero customization options. Players can also join or create their own clans to compete in tournaments for prizes.
