Recently, Diablo 4 was released on PC on Steam, but peak concurrent players did not even reach 20 thousand. Soon after, Blizzard decided to make the game free.
The free Diablo 4 promotion is valid for PC; PlayStation and Xbox owners are not invited. Access is provided until October 30, and players can only level up to level 20.
At the time of publication, Diablo 4 is not being offered as a free trial on Steam. The trial can only be found on Battle.net.
