The game is comprised exclusively of session-based online multiplayer activity, with the primary objective of each match being for the teams to destroy their opposing team's fortified stronghold called an Ancient Fortress. Each player assumes the role of a "hero", who is given the responsibility of participating in team combat, which generally takes place along a series of lanes that connect their opposing bases, lined with defensive towers. The gameplay elements are largely incorporated from Defense of the Ancients, with the game's lead designer (known as "IceFrog") being the longest-serving and current developer of the Warcraft III mod.[2] Dota 2 marks Valve's first fantasy, as well as Action RTS game.
