Dota 2 is a free-to-play multiplayer online battle arena game where two teams of five players each control unique heroes with distinct abilities, competing to destroy the enemy's Ancient while defending their own across three lanes filled with creeps, towers, and jungle camps. Players farm gold and experience to purchase items, level up skills, and execute strategic team plays in high-stakes matches that demand coordination, adaptation, and precise execution, often lasting 30-60 minutes.
