Heroes of Newerth is a multiplayer online battle arena game derived from the Warcraft III: The Frozen Throne custom map Defense of the Ancients.
Heroes of Newerth pits two teams of players against each other: the Legion and the Hellbourne. Both sides are based on opposite corners of the map in their respective bases. Bases consist of buildings, creep spawn points, towers, a hero spawning pool, and a central structure. The goal of the game is to either destroy the primary structure, the World Tree (Legion) or Sacrificial Shrine (Hellbourne), of the opposite base or force the other team to concede. Players achieve this by selecting heroes with unique skills to combat the other team.
The different game modes are Co-op, Player Hosted, Normal, and Casual. Co-op matches players either with other players or with bots against a team of bots. Player Hosted allows players to customize their games and then host them to a list for others to join. Casual is similar to a Normal game regarding layout and gameplay. However, they differ in other ways such as an included courier for each side at the start of the game and increased gold and experience earnings throughout each match.
