Heroes of Newerth has been enjoying some success behind the market leader League of Legends in the lucrative DotA genre, however their business model hasn't brought as many new players as S2 Games would have hoped and now they are switching to a three tiered free-to-play model.
The first tier is a Basic Account that every new player to Heroes of Newerth will get upon registering. After playing a certain amount of hours or purchase of Goblin Coins you can upgrade to a Verified Accound. Players who have bought Heroes of Newerth will be given Legacy accounts with free access to all heroes and the option of filtering out basic accounts from their matches.
Basic and Verifired users will be given access to a rotating pool of 15 heroes, and can add more heroes through microtransactions.
