What the developers have to say:

Why Early Access?

“Project Zomboid is a much more ambitious game than we could ever have hoped to fund ourselves. It has grown massively over the years, and it’s been a rollercoaster, but we now find ourselves in a stable financial situation with an overall positive reaction from the Steam community. We hope you will join us, but if not we understand. If you're not ready to jump in yet, then please consider us when we break out of Early Access.

How often do we update the community? 

We have weekly newsletters known as 'Thursdoids’ which we publish on our site and on Steam every Thursday. These detail what we've been up to during the week, often with sneak peeks of upcoming features, interviews and videos. If a blog is fairly dry they’ll sometimes only be posted on our website, but we've had this unbroken chain of ‘doids for a long time and (although when milestones have been reached we may switch to doing them every two weeks) we certainly intend to continue them for the foreseeable future.

How often do we update? 

We have a reputation that seems to diverge greatly when it comes to update frequency depending on who you ask. Many consider our game frequently updated, some consider us slow. Some public builds have arrived after three months, others with bigger features have taken more than six. You can see all our public build content, and the dates of release, here.
After a build is released and patched we reopen our public unstable beta, known as the IWBUMS (I Will Back Up My Save) branch – so the community can test it, and help out by reporting bugs. During these times, the greater proportion of the development calendar, we try to update the IWBUMS beta every Thursday.

Some features, particularly NPCs and the new animation system required for their implementation, have taken a very long time to implement. This is largely out of our commitment to getting the features right and them not disappointing on release, but it should be noted that we make no apology for delaying their release until we feel they would be enjoyed, live up to people’s expectations, and most importantly do not have a detrimental effect on the gameplay or stability of the game. 

We now work in partnership with several other companies to facilitate all this (General Arcade, and The Eccentric Ape for example) and have also greatly expanded our own staff in the past year.

We will admit to a few long waits between updates in the past, and far longer waits for big features, but we feel from community feedback that the majority of our customers are satisfied with the development of the game.

It should be pointed out too that the game has significant modding support, with map editors and full unrestricted lua modding access, and as such have a vibrant modding community for players to check out.

It should also be taken into consideration that the game is already very far through development, we’d estimate that we’re 75% complete at this point, and we also now have many 1000+ hour players. There is a lot of content to enjoy in the game already and we firmly and proudly believe it worth its current price as it stands.

Please consider reading some reviews if you are still unsure about the content of the game, the release frequency or the debate over the features that have been implemented and those still to come.

Again, full details of all updates to PZ since the release on Steam can be found here.

What is required for 1.0? 

Now vehicles have been released to PZ players there are two major features that are yet to be implemented, the first of which is a requirement for what we want to achieve with the second.

New animation system – a new animation and model system that will allow for more varied and engaging interactions within the Knox Event Exclusion Zone. Allowing better character clothing, more variation in zombies and far greater modding power for the community.

This system is now being developed alongside our friends at The Eccentric Ape, and will also allow for new animations for stealth mechanics (looking round corners, crouching behind walls, cover etc) as well as a rewrite of the combat system to leverage new animations to make combat more involved, intuitive and fluid. 

NPCS - A far reaching and in-depth NPC system with character relationships, personalities, and an emergent story engine that allows for diverse and emergent character based zombie survival story unique to every playthrough. This will also include the return of Kate and Baldspot who starred in the early alphas of the game. 

Several features also require either significant modifications, rewrites or completion before we could consider 1.0. 

Map completion - We still have a major city (our fictionalised version of Louisville, built to a more PZ scale) and an Army base. The rest of the map, which is already pretty vast, can be found here.

UI Rewrite - The UI isn’t perfect by any stretch. We would like to get a more intuitive and ergonomic UI system implemented. 

We avoid ETAs because Early Access development in particular is often filled with unknowns. We want to ensure we get these highly anticipated features right. 

In the meantime however we will continue to update the game and provide new features for our community to play with. While certain developers work alongside our friends at T.E.A. and General Arcade on the ‘bigger’ features we have others devoted to the day-to-day maintenance of the current game: balancing, new crafting recipes, vehicle gameplay, weather systems, professions etc.

What about after 1.0? 

At this point, once we feel we have fulfilled every promise we gave when the Project Zomboid site first launched (except the last one, ahem, ignore that. Absolutely no one wanted that, it turned out), as well as the extra things detailed above, and the game is sufficiently polished and bug free, we will launch the game as 1.0 and leave Early Access. 

What happens at this point depends entirely on whether the game is making money or not, but given the past solid performance of the game we see no reason why it shouldn’t be. Several developers within the team will likely start exploring our second project, however we have dedicated and passionate devs who were brought into the company via the Project Zomboid modding community, emotionally invested in the game, who are already a big part of the development and communicating with the community. As long as Project Zomboid is making enough to support their continued development of the game, and they are happy to continue working on it (which seems likely), we will continue making Project Zomboid. ”

Approximately how long will this game be in Early Access?

“See above!”

How is the full version planned to differ from the Early Access version?

“See above!”

What is the current state of the Early Access version?

“See above!”

Will the game be priced differently during and after Early Access?

“It will likely be £5, $8 more expensive once we hit 1.0. Due to our commitment to making sure early adopters get the cheapest price in appreciation of their early support PZ will never appear in sales that take it below the original alpha price of £5/$8 until we are a long time post 1.0. This commitment also means that, until 1.0 and the price increase, we will never be willing to go beyond a 40% sale.”

How are you planning on involving the Community in your development process?

“See above!”

Men with Ven

Hey all, here’s a quick run-down on where we’re at with Build 40 and beyond.

With the final touches being made to build 40, we’re now at the point of making a decision on what to do for the next build.

The issue with huge features like our new animation and clothing system, and everything that comes with it, living on another code branch is you tend to have to play catch-up a lot. The developers on the base game add or fix things on the non-animation branch, those changes need merging in – and due to the vast differences in the underlying code due to the animations this tends to add in extra work for the four guys over at TEA working on the new systems.

There comes a point you’ve just got to go all in and commit, or you’ll be playing catch-up forever. So (even though we have a few non-anim things ready to roll for Build 41 – like improved MP admin and gamepad functionality) as soon as build 40 is live and patched, we will be making the leap and merging in both the work we originally did, and all the extra animation tech that’s been worked on by TEA into the main development branch

This will mean that every developer at Indie Stone, including the chaps at TEA and at General Arcade, will all be working directly on the same version, and the focus of the entire team will be shifted onto making sure the entire game functions with the new animation system.

There is still a lot to do, there’s a lot of game there and things like cars and multiplayer will need some work to get functional, but this move will commit us and the next non-hotfix and non-patch build after 40 goes live will be the animations build.

It also means that blog updates about it all (once the dust has settled from the big switch-over) will hopefully become a bit clearer and less dry and technical. As well as, say, this week’s news that ‘Zac has made improvements to the BlendField renderer to help visualise how the anims blend together’ we can increasingly show how the PZ gameplay we all know and love/hate is coming together with the new visuals etc. Which will hopefully prove less frustrating.

Before this happens, though, TEA need to bed down a few things and prepare some documentation –and we need to get Build 40 out of the door and patched. So….

We just released version 40.17 to the IWBUMS beta, patchnotes for which are available here. We’re pretty much done with Build 40 at this point, but do need to smuggle in some more temperature balance and seasonal SFX.

We’re going to do a new internal test build for 40.18 tomorrow with some required fixes for admin commands and the chatbox, with the intention of then releasing it to IWBUMS early next week so we can have one final Community Megatest to shake out any remaining cobwebs.

There will, as always, be free PZ codes for people who help out – and due to the additions to the game mentioned below it should be a lot of fun. Please keep an eye on the forums for details.
  • Turbo has added climate and weather MP admin panels that should make for some really interesting roleplay and gameplay opportunities on PZ servers. Storms, snow and fog can be triggered at will to cover the entirety of the map – as well as overall climate values can be now be ticked to override what the game has conjured itself depending on what time of year it is. Server admins can also play around with how night appears, whether the game appears in monochrome etc We’re hoping that it’ll be a lot of fun.
  • Rain and snow now look like they hit the ground, which makes for a huge visual improvement. Rain then disappears, and snow fades out. Likewise, Turbo has also fixed how precipitation wasn’t clearly visible when zoomed in.

  • There’s also a bunch of fixes including: issues with various in-game tiles, gun sounds not being heard far enough away in multiplayer, two bugs that spawned a random zombie in a barricaded bathroom and the ability to learning from the TV and radio when asleep. Full list here!

This week’s van diagram from La_Chaise™. A general list of stuff added to PZ, and vids of features being worked on, is kept here – so you don’t have to plough through endless dev blogs for info. The Block of Italicised Text would like to direct your attention to the PZ Wiki should you feel like editing or amending something, and the PZ Mailing List that can send blogs like this and patch notes direct to your mailbox.

September 6


Hey all, Thursday greetings.

We’ve just released IWBUMS beta 40.14, which is another release that’s primarily fix and polish – our current aim for the devs working on this build being to make lots of quality of life corrections and adjustments while Turbo finishes his weather/climate work and the version can get a full public release. You can see the patch notes here.

To this end this version fixes missing raindrops, absent MP storms and other climate errors – while EP has also figured out the annoying sound volume and delayed sound issues, which should now be eradicated. The telepathic ‘terminator’ zeds trailing after players in MP that several of our IWBUMS testers have reported have also been stripped of their powers.

EP has also made improvements to alleviate longstanding woes with zombies appearing in your vision cone all-too-late in large buildings like the Mall, and Yuri has made fuel caps more accessible through his vehicle anti-clipping force-field.

EP has also been through all the various vehicle features and made them operate as you’d expect when the car battery is dead or uninstalled, also having them still operational until the car is powered down when the battery is removed and the engine is going. Another minor, but irritating and ancient, bug he’s figured out is the frozen food that’s been spawning in freezers long after the final power outage.

Please be aware that SpiffoSpace remains open for IWBUMS testing. This server, based in France, has no password and can be found by anyone running the beta (access details here). Once we’ve added in some admin power over weather (admin-triggered storm/snow/fog etc) we will be coordinating a Community Megatest on here.

Due for internal testing over the weekend and early next week, Turbo has redone the way the IWBUMS beta currently has changes in temperature, and resistance to hot and cold, impact on the player. Although it works okay-ish currently, the edges were too rough – and deaths were often broken/cheap.

His revamped system focuses on how resistance to the elements is calculated – and the way it takes hunger, thirst, worn clothing, wetness and exercise all into account should be a marked improvement. The temperature ‘safe zone’ range will be wider too, and the system takes ‘real time’ minutes into account rather than ‘game time’ – so fast forward peril is decreased, alongside being dead by dawn next to the embers of a camp fire.

The next version will also improve weather visuals to better distinguish rain from snow, and add in temperature conversions – so our Kentucky setting gets its proper and correct Fahrenheit readings, rather than horrid old European centigrade.


While the four guys over at T.E.A. continue to work on our new animations system, we thought it might be worthwhile mentioning the fifth horseman of that build: our music composer Zach Beever.

Since animations are such a fundamental evolution of the game, we want a whole bunch of new music to bring players along emotionally with the new visuals. Zach’s been working with us for months now, preparing a whole host of new tracks, many including familiar themes and motifs from old favourites.

Rather than drip them in one by one, and to give him time to work on them as a collective whole, we felt their impact would be far greater if they all went in together. To this end, behind the scenes, Zach has now completed 19 new music tracks, with more to come – and a part of one of the latest can be heard below.
For thoughts on his direction and inspiration for the music, we thought we’d ask the man himself.

“When I began work on the soundtrack some years ago, part of the overall vision was to incorporate instruments that were totally removed from the Kentucky setting. The thinking was to mirror the massive shift in the world—that whole zombie thing—with an equally big change in the (expected) music. What could have possibly been played by the banjo and fiddle, for example, went to the tar and duduk.”

“Recently, though, the team brought up a player’s suggestion to reexamine this and tie in aspects of the local music. This took some thought and a good bit of experimentation, as I didn’t want to upset the identity we had created for Zomboid.”

“The result is a new set of tracks that, I believe, expand on the old ones faithfully—the mood is still there, but now we’ve got American-style sounds mixing with the more middle-eastern sounding ones. When everything’s heard together, I hope the occasional appearance of these instruments (and their distinct playing styles) hints at the past world.”

Behind the scenes there’s currently a lot of conversation about revamps of existing systems (farming, last week’s thoughts on polishing the power outage etc) but something else we’re discussing are ‘survival-style’ skill and recipe-based enhancements to vehicles. To which end, we thought we’d float this image of our potential direction with this in front of the community – to gauge opinion and gather some feedback.

Please note that this is NOT a final representation – it requires a full art pass, not to mention a lot of coding work that will likely come from General Arcade’s Yuri for a future build. It does, however, show how a modular model system could work – and we’d like your thoughts on it.


It’s currently the Annual Penisham Celebration on our forums. Feel free to join in, but be aware that Penisham will only be available for another five days.
