The developers working on Diablo 4 have said the game's beta tests have been "transformational" and ensured the upcoming MMORPG a smooth launch.
In an interview with Eurogamer, Diablo 4 art director John Mueller and associate game director Joe Piepiora discussed the importance of the last few open betas, explaining that they were "not marketing betas" and essential in making sure the game's full launch goes as smooth as possible.
