Unfortunately, and we suppose not surprisingly, Blizzard has revealed that for Diablo 2: Resurrected, they will not be bringing back support for LAN multiplayer. According to the FAQ page, “TCP/IP support will not be available in the upcoming Beta or the final game. After careful deliberation, we will no longer be supporting this option as we identified potential security risks and are committed to safeguarding the player experience.”
Like we said, it shouldn’t be too surprising that these types of multiplayer gaming is being deprecated. Our internet is a lot faster and companies have invested into the infrastructures of their own networks. It also gives them better control over the games, weed out cheaters, and so on, so it doesn’t really make sense for them to maintain an older standard.
Diablo 2: Resurrected was announced earlier this year and is scheduled for a release on the 23rd of September. Blizzard has announced that they will be hosting an Early Access beta on the 13th of August for those who pre-purchased the game, and an open beta will be available on the 20th of August.
