Heroes of Newerth puts two teams of players against each other: the Legion and the Hellbourne. Both teams are based at opposite sides of a map. The standard map is split into three continuous 'lanes' (Two in one of the lesser-played maps), running from one base to the other. Defensive towers are positioned evenly through each lane, until the lanes terminate at a team's base. Bases are strongly defended with extra defensive towers, and buildings from which units spawn. These units, termed 'creeps' are spawned every thirty seconds, and run along their lane until they meet opposition - which they then attack. Victory is achieved when one of the teams manages to push into the base of the opposing team, and destroys their primary structure; the Hellbourne's 'Sacrificial Shrine', or the Legion's 'Tree of Life'. At any point after fifteen minutes has expired a team can choose to concede defeat - this loses them the game and requires a unanimous team vote to pass or a 'four of five' vote after the thirty minute mark.
