Diablo 4 will host a confidential closed End Game beta, and it will be the first opportunity for select players to participate in testing an early version of the game.
Mainly, Blizzard wants “experts” to participate in the confidential closed beta.
If you have not received an email invite to the tester by November 18, you were not selected to participate.
Specifically, it will be using gameplay data to invite a limited number of Diablo players who have recently spent “significant amounts of time” playing the end-game experiences of previous titles.
