The game was part funded through a Kickstarter crowdfunding campaign, raising $137,707 in April 2014. Originally intended to follow an up-front pricing model, the game switched to a free-to-play model in 2015. The developers believed that a free-to-play model would allow for ongoing updates to the game rather than relying on less regular expansion packs. The game entered open beta testing in October 2015, and was released in April 2016 , 2016 on both Microsoft Windows and OS X platforms. The iOS version, however, was subsequently removed, and the game exists only for Windows. The first major expansion "Denizens of Shim'zar" was released in August 2016. A second expansion, "Rise of the Bloodborn" was released in December 2016. A third, "Ancient Bonds" followed in March 2017. The fourth, "Unearthed Prophecy" was released in July 2017. The fifth, "Immortal Vanguard" was released in November 2017. The sixth and latest expansion, "Trial of Mythron" was released in November 2018.
