The “Family & Friends” closed beta testing for Diablo 4 is currently under way and some brand new screenshots have been leaked from it. These screenshots show off the game’s character creation and some of the skill trees.
Diablo IV will be an always-online game, and will not offer an offline mode. We also don’t know whether Blizzard will allow modders to enable an unofficial offline mode or not.
The game will also have cosmetic micro-transactions. Additionally, Blizzard is looking into enabling cross-play support between all platforms.
