Buy & Download

Welcome to Knox County

Project Zomboid is an alpha-funded game, and is still in active development. When you buy you purchase a lifetime license, which entitles you to the current build and all future updates.

Legal Info

Due to us using the money to actively fund development, and therefore to protect ourselves and our transaction handlers from the risk of some mass refund request, we need to state that we do not accept refunds (though in extenuating circumstances we may consider it). Your key will remain valid for all future updates of Project Zomboid and we intend to support it for many years to come. We are not legally bound to provide additional updates, and you are paying for the product as it stands now.

All purchases apply to PC, Mac and Linux desktop versions of the current game only – and not any potential future sequels or offshoots related to the game.

Buy the game

Buy through this Desura widget and get a Steam key directly from this page!


Download the game

The latest Project Zomboid build is available on Desura – both as an auto-update with the Desura client, and as a direct download from the ‘Purchased Downloads’ of a logged-in Desura user’s Project Zomboid page

You do not have to run the Desura client itself (the game is downloadable directly) but you may miss out on smaller tweaks and patches that are fed in through the client. We will, however, be updating the direct download with each major build release.

Public Test Builds of upcoming versions can often be found in the PZ Downloads section of our forum – but have been released for bug-chasing, and as such might not be the smoothest ride. These are for people who’ve paid for our alpha, and will require you to input your Desura key the first time you play.

Returning player key retrieval

If you have previously bought PZ via Google Checkout and want your Desura or Steam key OR if you’re a Desura player wanting to know how to find your Steam key – visit this helpful page.


A demo is now available on both Steam and Desura.
