When asked about TCP/IP support, Blizzard said it “will no longer be supporting this option as we identified potential security risks.” The news came as part of an FAQ post, detailing the key questions about the upcoming remaster. Worse still, this applies to both the upcoming beta and the full game - and it’s sad news for fans. That means you won’t be able to battle your way through hordes of enemies with friends over local multiplayer.
A blog post on the official Blizzard website confirms the fan-favorite feature won’t be making a return.
As the Diablo 2 Resurrected open beta kicks off soon, there’s bad news for fans of the original: The beloved TCP/IP local multiplayer mode will not be supported.
