Heroes of the Storm, Blizzard's team-based MOBA (Multiplayer online battle arena) title, is free-to-play and has been since its launch, but most characters within the game, of which there are 88, cost either premium currency or in-game currency to unlock. Those who have been looking to try specific characters out can now do so for free, however, as Blizzard Entertainment is running a campaign in which all heroes are unlocked.
The character roster will be completely unlocked until April 2, so you have some time to take advantage of this.
