The huge Project Zomboid build 42 finally gets multiplayer just in time for the holidays
by
Wow - that sure took a while! A year since the first part of build 42 released and just in time for the holidays, Project Zomboid build 42 finally goes online. Read the full article here: https://www.gamingonlinux.com/2025/12/the-huge-project-zomboid-build-42-finally-gets-multiplayer-just-in-time-for-the-holidays/
It's taken a year, but Project Zomboid multiplayer has finally opened its doors again, just in time for the holidays
Unstable Build 42.13, which contains multiplayer support, has been released. Merry Christmas. Ho ho ho. https://www.youtube.com/watch?v=lYKS02PYF7E IMPORTANT NOTES Multiplayer is WIP and has been released for stress testing. For the best experience you are STRONGLY advised to play on whitelisted servers or in Steam co-op. It is currently inadvisable to have more than 20 players on a server. This will be further improved. Please do not use debug during MP games. This will impact negatively on server performance. Please disable all mods. Even client ones. Ragdoll functionality has been disabled in MP. This will be added in later patches. Please be aware that future updates to the Unstable branch WILL disrupt ongoing MP games. Saves created before Unstable 42.13 are no longer compatible. The conversion process will very likely break elements of your game. Please back up your save before continuing, after which debug could potentially be used to restore any lost items, animals, carrying ca...

Build 42.12.3 UNSTABLE Hotfix Released
by Higgs
FIXED: Fixed missing biomes (e.g stones, twigs, boulders can be found in the world again) Fixed not being able to sharpen blades beyond Handle Condition.
Project Zomboid's new design director probably has more in-game hours than you, and he worked on Halo to boot
Minor additional Hotfix for 42.12: - Fixed Linux build not starting. - Fixed language encoding for some languages. FIXED - Fixed shove bug. The call to IsoGameCharacter.Hit() had to have bIgnoreDamage == true for the shove through zombie bug not to occur. - Fixed melee and ranged targets for other split-screen players being highlighted. - Fixed very mysterious buildings that were blocking the highway south of Muldraugh. - Fixed EffectsManager double-freeing models. - Fixed a vulnerability in the Lua deletion code. Our thanks to Jab for reporting this. This was included in a previous patch to both B41 and B42 but not referenced until now for security reasons as it affected both.

{STEAM_CLAN_IMAGE}/4460946/eb5a25c671ba5a323cf4becf271562d0ade71b49.png Hi all, we do hope you’re well and surviving okay. This is a quick blog to update you with what’s been going on in the back rooms on Project Zomboid over the past twelve months. Which is quite a lot – and what we hope you agree is good and exciting news. The first thing to mention, and the reason for the timing of this blog, is our new Design Director. Christian Allen (aka Serellan in the community and on the Workshop) has been a Lead Designer on many and various games – with Ghost Recon: Advanced Warfighter and Halo: Reach perhaps the biggest names on his CV. More importantly, however, he also has over 5000 hours in Project Zomboid both as a player and a modder – which makes him firmly one of us. Or, perhaps even more importantly, it firmly makes him one of you. He has been with us for a month now, and his first mission has been to muck in with the team and work on the bits of Build 42 where long-established playe...
42.12.1 UNSTABLE Hotfix Released
by nasKo
Additional fixes, including a fix to the Shoving bug, will be provided in a 42.12.2 release. - Added priority logic for ballistic targets body part colliders: Head > Spine > Pelvis > Others, and updated camera target selection to prioritize body parts. This significantly improves headshot targeting across all firearms. - Disabled most aspects of the visual system that blacked out unseen rooms. This has been taken back into the shop for future work, however the system and the power to fade out rooms remains in the code. - Fixed missing BodyLocationGroup.getOrCreateLocation(String) which was needed by clothing mods. - Fixed non-exposed WeaponCategory enum in Lua which was needed by mods. - Fixed the toxic effect of generators not being updated for player-made rooms whenever roofs are added or removed. - Fixed issue with ripping clothing returning dirty rags for clean clothes and vice versa - Fixed a performance drop when the player-made-building code runs, when there are no player-made b...
New Project Zomboid update improves ranged combat, shotguns, and chocolate milk

This brings ranged damage into line with how melee combat works, head shots will receive 3x damage, legs and arms get dealt far less. - Fixed Shotgun Targeting Bug. Zombies were dodging your pellets. When aiming a shotgun at a specific body part, the other pellets were ...
