It's been reported that the game initially started work on Unreal Engine, before shifting to the internal engine Synapse, which also proved to be a troublesome toolset.
Matt Booty, Microsoft's president of game content and studios, says some of the developers who were working on the game will be shifted over to other Blizzard projects.
The game will also allegedly feature stylized and cartoony art similar to what's seen in the Overwatch games.
Based on footage seen several months ago, Windows Central's Jez Corden said it features base-building, players shops, and fairy tale aesthetics.
