S2 Games, the developers behind the Dota clone Heroes of Newerth, has just announced that the game will now be free-to-play for everyone as of this moment.
"This was a strategic transition intended to grow our community and solidify HoN as a major player in the ever-growing genre," said a statement released on the game's forums.
People who already purchased a Heroes of Newerth account received an upgrade to their accounts. "As an existing player, your account has been automatically upgraded to a Legacy account, giving you free access to the general hero pool."
Legacy accounts also allow players to have an option to play in "Verified Only Games" which means against players who already own an account. This ensures beginners are not overwhelmed by the already established and experienced community.
