Next week is a big one for Diablo 4, because it marks the launch of the game’s first-ever Public Test Realm (PTR) – a test server where players will be given early access to several key gameplay changes ahead of their release to the general public.
As you’d expect, the goal is for Blizzard to collect as much feedback and data as possible before implementing such massive overhauls as this one is bringing. If all goes well, all players will get to experience the result of that work with Season 4 in May.
