Wrath of Heroes was first announced on August 16, 2011 by BioWare at the Gamescom 2011. BioWare also presented a brief demo of Wrath of Heroes at Gamescom. The game was also presented on August 28 at the PAX Prime 2011.
On April 10, 2012, Wrath of Heroes entered open beta.
On February 28, 2013, EA announced the open beta would be shut down and the project canceled; this occurred as announced on March 29, 2013. The FAQ on EA's website regarding Wrath of Heroes states "Mythic as a studio is undergoing a paradigm shift as we shift our focus to mobile. As part of this pivot, we had to make a few changes and reallocate resources to support this new direction. As such, we took a long look at Wrath of Heroes and despite its strong IP, gameplay, and community support; we decided not to continue the service past its Beta and instead concentrate those resources on our new endeavors."
The assumption however is the game was not making enough money for EA to justify launching from beta.
