The plan of the game is based on several"columns", among which the older fans will likely be pleased with, that this action will be a lot darker and more horror than Diablo III, who took the animation.

They also find it difficult to determine how to incorporate microtransaction options that the team was experiencing in D3. Diablo IV remains in a really early development phase, and may not appear until 2020 at the earliest. menos
