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 find ourselves in a stable financial situation with an overwhelmingly 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 'Mondoid's, which we publish on our site and as a Steam announcement every Monday (unsurprisingly) as a small tonic to the depressing 'back to work' feeling. These detail what we've been up to during the week, often with sneak peeks of upcoming features, interviews, videos and all that goodness. We've had an unbroken chain of Mondoids for a long time now, and plan to continue them as long as Project Zomboid is developed. We also communicate with our community directly on our own forums and Steam forums, often with changelists for upcoming builds.

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. In recent times it’s rare we don’t have a release within a month (including beta releases), and these always contain new gameplay features or major tweaks to the gameplay.

Some features, particularly NPCs, have taken a 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 will admit to a few long waits between updates in the past, but we feel from community feedback that the majority of our customers are very 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. We have a vibrant modding community that can help plug the gap between updates. It should also be taken into consideration that the game is already very far through development, to the point where we now have 1900+ 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 or the release frequency.

Details of major milestones can be found below.

What is required for 1.0?

Two major features are yet to be implemented into the game, both of which are currently in full-time development each with dedicated full-time developer support. These are:

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 also includes the tutorial, a return of Kate and Baldspot who starred in the early alphas of the game.

Vehicles - Fully physics modelled 3D vehicles, siphoning petrol, mechanics skills.

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

Map completion - We still have a major city, an army base, more wilderness, and several small towns to implement to the game map.

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

Stealth / Combat - New animations to allow 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.

We want to have all this in the can this year. However, we tend to avoid ETAs because Early Access development in particular is often filled with unknowns and 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. One of our developers full time responsibility is providing frequent and new items, crafting recipes, skills and survival gameplay elements to fill out any holes in gameplay, and provide frequent feature rich game updates in line with community feedback, while the other developers focus on finishing these specific remaining major features.

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 at this point, however we have dedicated and passionate developers 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 indefinitely as long as there is interest.

That all said, we can’t make any solid promises beyond the 1.0 mark, however there are countless things we would love to do that go way beyond 1.0 and sales make us confident that we’ll get the opportunity to explore them. Truth be told, given that it was Zomboid that put the money in the bank in the first place, as long as our company is secure and we can fund any other project's development comfortably, it's very probable we'd be willing to put some money back into the game beyond the point it's sustaining itself if there are any features in particular we can't bear to leave out of the game. Words are wind though, and all we can do is guess where we'll all be by then. We really want to keep this train going as long as we can though, as long as it continues to the benefit of the game. At which point the modders will hopefully take the mantle with almost unlimited access to the game's core.

Development Costs

Here we hope to give you a better idea of how the sales revenue from Project Zomboid will support development of the game. While we will keep particular developers salaries confidential, we would like to offer a breakdown of developer and office locations, along with the average rent costs, reported on for the Indie Stone offices, along with each developer's location to give you an idea of relative studio costs. It's become clear to us recently how significantly this factors into Early Access games chance of continuing development and we hope others will follow suit in divulging this information.

All percentages are in comparison to New York City (100%) - Other examples would be San Francisco (98.66%), London (93.81%), Moscow (52.71%) and Delhi (9.53%). The lower the % the further your purchase of an Early Access game will go to fund development (or more crucially how long that money will last), as accommodation costs correlate pretty closely with expected salaries and costs of living and working in that location. (Please note that in several cases the developer lives sufficiently outside the given city to make the actual %s likely much lower than reported)

3x Developers + Office
Newcastle Upon Tyne, United Kingdom - 32.37%

1x Developer
Brighton, United Kingdom - 56.37%

1x Developer
Toronto, Canada - 51.78%

1x Developer
Surrey, Canada - 30.87%

1x Developer
Lille, France - 31.59%

Monthly development costs are currently recouped within approximately the first 1.5 weeks of the month on average, which means at present each month produces extra funds to further develop the game should sales dry up. This does not include sales or other promotions.

What if PZ stopped making any money tomorrow?

The Indie Stone have made sufficient sales since launch on Early Access to ensure that if the game stopped selling any copies tomorrow, the entire PZ dev team could carry on funded development as at present, with no reduction in workforce, for at least the next two years, potentially longer. This would not be an ideal situation for us, of course, but we are committed to finishing every major planned feature before we consider moving the game to 1.0. Considering the financial situation we are in at present, the chances we will not be able to fund the remaining development of the game are quite small.

In the worst (and least likely) possible of financial cases that required the disbandment of all paid developers of the game, 4 of the listed developers are directors of The Indie Stone with an invested interest in the success of the game and company, who would cut their income significantly and/or supplement development of the game with other work to get through any financial difficulties. Despite this no doubt causing progress to slow significantly, the 4 directors hold all required skills to continue development of the game during this nightmare scenario.”

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, we will never appear on bundles, or in sales that take it to or below the original alpha price of £5, $8 until 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!”

Death Cab for Zombie

Evening all, we do hope y’all are well.

We’re hopeful that today’s public IWBUMS release (39.64) will be the last before the full vehicles release. It contains:
  • A few physics and vehicular position fixes that will hopefully help those playing on co-op and dedicated servers.
  • Improvements to loot kept on car seats, tweaks to the item disassembly system, and the removed item transfer progress bar being restored by public demand.
  • Fixes to faulty item spawn rates (especially skill books) in MP, sheet rope levitation, aspects of zombie pathfinding, missing collision on various objects and various bugs squashed when transferring items between containers. And many other fixes besides.
One other thing we might like to get into the build before release is some recent work that General Arcade’s Yuri has been doing on our Steam integration. We anticipate that quite a few people will want to come back to PZ to check out the vehicles, alongside their friends, and as such it seemed a good time to fix up some player invite issues – namely that PZ has always struggled with inviting players into games when both players already had the game open. We’ve got a build running that smoothens this out backstage, and may also consider adding this to the mix if it’s working as intended.

Please also note that, as mentioned last week, in preparation for the vehicles release, the PZ map has been updated with Build 39’s countryside/vehicle exploration additions between Riverside and Rosewood. For community mappers and interested parties: new versions of PZ tools TileZed and WorldZed have been released, alongside the latest array of Tileset images.

As regular readers will know, our Technical Director friend Bitbaboon Mark now has his own company called TEA – and he and his cohorts Zac, Chris, Gar and Schnitz are working on getting the new anims and models ready for the PZ codebase to switch over to them.

This week from a technical standpoint they’ve been sorting meshes/textures and data that’s loaded from .X files and have hooked up character masks and ‘items’ to create individual characters from with everything hooked up correctly.

The intention is to have the character config inside the dev/modding tool AnimZed – so people can quickly add and update meshes and put them onto characters to validate alongside the animations themselves. In fact Zac has a ‘random’ create for characters all running from AnimZed, and it looks a little bit like this.

Music credit: MrEldfuel from free sounds.

Please note: there’s clearly lots of different outfits and items on-show in this video – initial anims build releases will not contain everything seen above, especially if it involves combat markedly different to what’s already in-game. This is purely to show what AnimZed can do now, and the way that anim stances now change based on the weapon being held – which is all data-driven now. (Please also note: Spiffo’s Restaurant mascot outfits are supposed to look a bit… threadbare).

Turbo is working on his remedy for the new snow/fog/storms system – in that it’s all fine and dandy having a climate system with morning fog and real-time storms forming and passing overhead, but not helpful when (as it currently is in-game) you can’t look out of the window to see what the weather’s doing.

As such he has been exploring the possibility of using screen masking to allow for the player’s building to not be included in the rendering of rain, fog or other atmospheric effects. This will mean they will be visible to the character through windows, instead of being turned off across the screen when a player enters the house.

Please note this is just a proof of concept and not fully implemented into the game yet.


Meanwhile Stas continues his gamepad set-up improvements, Zach continues with his additions to the PZ soundtrack and Mash continues to build some of the larger new building locations to place within the expansion out to Louisville.

Twas the night before GDPR, when all through the house – not a creature was stirring, not even an updated privacy policy.

This week’s fare from ㊣ $ℏìᶄ ㊣ . 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 Centralized 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.

Monkey Bizness


The Build 39 Vehicles build (playable in public IWBUMS beta) is essentially ready to go, but we need to be sure that a couple of issues have been solved by today’s release of Build 39.57: one that saw crowds of zombies pinging vehicles off roads in MP, and another on some dedicated servers that had zeds attracted to a vehicle’s previous position that we also think was to do with the physics interpolation. [So please let us know if you encounter either!]

39.57 also improves the way vehicles are arranged in parking stalls by adding directional pointers to the mix, addresses issues with watch alarms, adds extra options to help you tailor/toggle world degradation (erosion) in the game and some tweaks to help modders with the change to the vehicles build. Amidst a lot of under the hood stuff to keep stuff ticking over. EDIT: A complete changelist will appear here in the next day or so, but due to last minute issue with the latest code we’ve released a build that was already in testing and thus we’ll have to recompile the changelist to suit.

In the mean-time let’s go round the houses and find out what other PZ types are up to:

Last week we announced that we’d teamed up with a gang of renegade coders called The Eccentric Ape – ably led by our current anims-focussed Technical Director whizz (Bitbaboon) Mark. This past week has seen them getting up to speed with PZ, and right now they’re getting their hands dirty in the codebase. The plan is for them to do a big push on the animation system, and overall intention is that we’ll be working alongside them on many of our big features going forward.

So, for the next little while TEA’s Grant is fixing up remaining issues with layer/node and blending code, and then adding in the common state conditions that animations will ‘trigger’ – stuff like collision being on/off for combat and swings. Snitz, meanwhile, is setting to work on movement, idle and swing states to remove anything still hard coded and tie them instead to the new in-game variables.

Finally, Zac and Gaz are working on AnimZed, making it more user friendly, filtering and sorting the anims into the first set of released animations and focussing on it from the end user perspective. By the time this push is complete the system should be in a state where Animator Martin, and ultimately modders, can dive in and start layering new anims for the remaining states with very little required coder intervention.

Turbo’s big challenge at the moment with the new precipitation and fog that go hand in hand with his simulated climate system is how to handle it when you look out of windows – in the current game rain isn’t visible outside, and this bug will become much clearer with better rain and fog effects. Particles currently get drawn after the world has been drawn, and the weather is drawn over this final image – so we need a solution for this so you can check the weather outside your safehouse without walking out into it.

We anticipate that looking out of a window when hearing the noise of, for an example, an approaching thunderstorm (thunderclaps at the correct timing, taking into account to your distance away on the map from lightning and the centre of the storm) will be a much more common occurrence with this new system – likewise with checking out the fog. As such it’s something we need to fix up before release.

While he puzzles this all out alongside our other coders, Turbs is also creating a new sound bank for ambient sounds to signal seasonal change. He’s currently got a supply of forest zone sounds, insect noise, rain effects for both indoors and outdoors, extra SFX for heavy weather, birdsong and indoor/outdoor wind effects.

He intends to have it so that, for example, on a hot summer afternoon with little to no wind you can hear the crickets chirping – and for birds to become silent when heavy weather hits. It’s intended to be soft background noise, but if implemented well should really improve your sense of the time of year – and the current weather state created by the simulated climate system. After a meeting with the PZ art brigade Turbo is also going to add some more direction to his ‘clouds overhead’ effect, as currently they look a little too smoke-like.

Bitbaboon Steve is finishing off our updated internal build system, while Connall is investigating ways to help our community translators keep up to date with translation strings that are updated from build to build. Mash continues with Louisville, while RingoD is building a wider roster of house and apartment buildings that she can drop into residential areas when she moves into the suburbs.

When they return from Russian Victory Day vacations General Arcade’s Yuri is working on MP network physics, and Stas continues his work to improve gamepad and mouse settings/bindings. ChrisW is also back with us and will work on giving final polish to his existing rooftop occlusion system when it comes to player-built structures, before returning to his work on Sims-style interior cutaways in houses.

Due to a necessary forum upgrade we’re also having to decommission our current Bug Tracker, which is annoying but has to be done unfortunately. We’ve harvested all the longstanding issues that were present in it, so if you see any of your reports disappearing – please don’t worry as they have a new home in our internal system. We’ll work on getting a decent replacement in the weeks ahead.

This week’s 911 call out from Ghost. 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. We also live on Twitter right hereOur Discord is open for chat and hijinks too. The BOIT would like to apologise to Mark for calling T.E.A. ‘The Educated Ape’ last week instead of ‘Eccentric’, although that would also have been a good name for his new company.

About This Game

Project Zomboid is an open-ended zombie-infested sandbox. It asks one simple question – how will you die? 

In the towns of Muldraugh and West Point, survivors must loot houses, build defences and do their utmost to delay their inevitable death day by day. No help is coming – their continued survival relies on their own cunning, luck and ability to evade a relentless horde.

Current Features

  • Hardcore Sandbox Zombie Survival Game with a focus on realistic survival.
  • Online multiplayer survival with persistent player run servers.
  • Local 4 player split-screen co-op
  • Hundreds of zombies with swarm mechanics and in-depth visual and hearing systems.
  • Full line of sight system and real-time lighting, sound and visibility mechanics. Hide in the shadows, keep quiet and keep the lights off at night, or at least hang sheets over the windows.
  • Vast and growing map (loosely based on a real world location) for you to explore, loot and set up your fortress. Check out Blindcoder’s map project:
  • Use tools and items to craft weapons, barricade and cook. You can even build zombie proof forts by chopping trees, sawing wood and scavenging supplies.
  • Deal with depression, boredom, hunger, thirst and illness while trying to survive.
  • Day turns to night. The electricity falters. Hordes migrate. Winter draws in. Nature gradually starts to take over.
  • Farming, trapping, fishing, carpentry, cooking, trapping, character customization, skills and perks that develop based on what you do in-game.
  • Proper zombies that don’t run. (Unless you tell them to in the sandbox menu).
  • A ton of amazing atmospheric music tracks by the prodigy that is Zach Beever.
  • Imaginative Challenge scenarios and instant action ‘Last Stand’ mode, on top of regular Sandbox and Survival 
  • Full, open and powerful Lua modding support.
  • Xbox Controller Gamepad support on Windows. [Others pads can be set up manually. Gamepad support not currently available on Mac]

    We’re a small team at the moment, but we’re also committed to providing the following:

    Planned Features:

  • The return of our PZ Stories mode that also serves as first ever tutorial actively trying to kill you at every turn. Kate and Baldspot return!
  • In-depth and varied NPC encounters driven in a persistent world, powered by a metagame system that turns each play-through into your very own zombie survival movie with emergent narrative gameplay.
  • Constant expansion of the countryside and cities around Muldraugh and West Point
  • Full wilderness survival systems, animals and hunting for food.
  • More items, crafting recipes, weapons and gameplay systems.
  • Steam Workshop and Achievements support
