B42 CHECKLIST

Project Zomboid · published 28 Jul 2026, 12:58 UTC

All newsPlayers around this dateRead on Steam

Tomorrow, Wednesday 29th July, we will be releasing Build 42 of Project Zomboid!

This is a quick post to ensure that those who want to continue playing Build 41 are aware of how they can do so with minimal disruption, and indeed to tick off a few other items to be aware of.

Apologies for the overall boring post! Hopefully yesterday’s map overhaul excitement counterbalances it a little.

THOSE WANTING TO STAY ON 41

Build 41 savegames clearly will not be compatible with Build 42.

If you are a Build 41 player who wants to minimise disruption on the 42 launch, or a server owner / online player who wants to continue on Build 41, then there is already a beta channel for you (and your players) to move over to before the event.

To reiterate: you can safely swap to the Build 41 beta now.

To do so:

  1. Right-click PZ in your Steam library.

  2. Select “Properties”.

  3. Under “Game Versions & Betas” select “legacy41”.

THOSE WANTING TO FINISH AN UNSTABLE 42.19 GAME

Due to additional map content being added, existing saves on Unstable 42.19 will not be compatible with 42.20.

To continue your Unstable game you can opt-in to the new “42.19” beta now also, again to minimise your disruption tomorrow. 

To do so:

  1. Right-click PZ in your Steam library.

  2. Select “Properties”.

  3. Under “Game Versions & Betas” select “42.19”.

STREAMERS AND YOUTUBERS

Streamers and YouTubers who have been given slightly early access to the map overhaul in Build 42.20, and are being allowed to post and broadcast their content from 10AM BST / 5AM EDT / 11AM CEST / 12PM EEST on Wednesday for a few hours preceding the official launch.

So if you fancy spoiling it all for yourself, please keep watching relevant channels on YouTube, Twitch and wherever else you get your content creators from!

PRICE RISE

As with the launch of Build 41, there will be a rise in price for Project Zomboid alongside the release of Build 42 – although not one that many would consider a huge one.

The game will continue to be what we consider to be reasonably priced and good value for the gameplay available. This change will apply across storefronts and regions once 42.20 launches to Stable; if you want to pick up the game at the current price (or for a friend), act now.

LOCALIZATION

Community Localization work is an ongoing project, with an amazing response from players all over the world, and will continue to be patched in beyond launch.Once the current iteration of Community Localization has been released we will be welcoming feedback on what’s working for our many different nationalities who play the game – and what isn’t.

Please provide feedback in the #localisation_feedback channel on The Official Project Zomboid Discord Server when the time arises.

Other localization items of note:

  • Thanks to our amazing community translators we are adding Czech, Indonesian, Spanish (Argentina) and Spanish (Mexico) to our list! More will come in future also.

  • Chinese (Simplified), Chinese (Traditional), and Catalan have font issues we are aware of and are actively working on. They will be addressed in a future update.

  • Some available languages still require a lot of work, so please be aware that currently Catalan, Romanian and Spanish (Chile) still feature a lot of English vocabulary.

Gracias, Merci, Danke, Grazie, 谢谢, ありがとう, Obrigado, Спасибо and 감사합니다!

UNTIL TOMORROW!

That’s probably about it, here’s a few trailers and interviews with the team in case you’ve missed any of them.
