Project Zomboid has released its first major build update since 2021, titled build 42.20, which includes a comprehensive overhaul of Knox County, redesigning seven towns with unique architectural styles and enhanced landscaping. The update introduces new animals, refined hunting and trapping systems, improvements to the stealth system, fishing mechanics, and the ability to drag corpses. The game's price has increased from £16.75 to £22.50, yet it has seen a record-breaking 79,552 concurrent players on Steam. Future updates are expected to reintroduce NPC survivors to Knox County.
