Diablo 4's new Lord of Hatred expansion is such a foundational shakeup to the ARPG's core systems - not to mention a massive content drop - that you'd be forgiven for thinking it's a whole new game. And as it turns out, it was in development even before the base game launched back in May 2023, a testament to the amount of development resources Blizzard threw at this thing.
It's wild to think that Diablo 4 itself, more than a dozen seasons worth of new content, the Vessel of Hatred DLC, and countless balance updates have dropped in the span of time that Lord of Hatred has been in development, but according to associate game director Zaven Haroutunian, that's exactly the case, and it really goes to show how huge Blizzard has become.
