Diablo 4 just had its Early Access weekend and will be in Open Beta from March 24 to the 26, which means players are enjoying leveling characters and seeing what the game has to offer so far, while also wondering if beta progress will transfer to the full game. The Open Beta period allows players to experience the Prologue and Act 1 in the game and reach up to level 25 with any of the character classes. The full zone of Fractured Peaks, the first zone of the game, will be open for players to explore while fighting off hordes of demons and world-bosses.
