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!”

Under the Hood

The vehicles branch has a lot of momentum at present, so right now there’s currently a lot being done behind the scenes to pave the way for cars, emergency vehicles and the like.

First off, however, now RJ is back in the dev saddle after his paternity leave we need to finalise and release Build 37 – primary highlights of which are in-game maps players can annotate, pre-annotated survivor maps for SP, new cooking features and many/varied other tweaks and fixes. To this end we’ll be releasing version 37.4 into the IWBUMS public beta tomorrow.

In the run-up to vehicles and anims we are taking the opportunity to fix as many of the longstanding bugs that’ve built up as we possibly can – including some long-term UI/moodle ones that’ve been a pain to those who play in split-screen for a fair old while. This bug tracker purge is ongoing, and if you want to help out with a report then the tracker lives here.

This week we finalized the in-house document that we’ll be putting in place to ensure that vehicles are a health hazard as much as a survival asset, that we’ll detail as stuff is built into the game. In the interim, though, what’s been done this past week to ease in and facilitate EasyPickins’ and General Arcade’s long-promised physics-enhanced vehicles into a new test build, and beyond?


Engine smoothening. One of General Arcade’s primary vehicles branch entanglements has been in improving PZ’s capabilities in terms of map streaming and pop-up – but another issue we’ve butted up against frequently in the past is stuttering caused by Java’s resident gremlin ‘the garbage collector’. As such this week TIS have successfully spelunked into the deepest depths of PZ’s code to optimize affairs, which will have an impact game-wide and also make prolonged vehicle travel through busy/forested areas a far smoother ride.

Road decorating. When the a vehicles test build is released there won’t be a car on every drive (although vehicle proliferation will be a sandbox option) and as such we’ll be adding reasoning to the radio/TV lore and we also intend to have build-ups of destroyed vehicles on roads – especially towards the edge of the current map. It’s possible we’ll face engine limitations, but what we’re aiming for is a feeling of failed escapes from the Exclusion Zone when the sickness first descended on the area.

Anims Compatibility Ensuring. Given the recent surge in activity that vehicles work finally coming to the boil has wrought, and the possibility that this will see them going into the full game prior to anims, a focus this week has been in ensuring that vehicles and anims systems will play nicely together. The main difference between the two branches is that the animation build effectively removes a system that’s been in the game since 3D models were first introduced: the fact that every frame renders the 3D characters into 2D sprites that draw in place.

Now, in the internal anims branch, isometric projection draws the characters in-place at the right place in the screen. This is a major optimization that removes the requirement of off-screen FBOs that are unavailable on some older cards, as well as optimizing the draw speed and makes the root motion (as well as interactions between multiple characters) work properly since the models and game world share the same coordinate space. As such, right now we’re sucking the vehicle juice out of their branch and redistributing it into our anims work – to make sure it all gels together when the time comes. There will be other things that need fixing up, but this is the main issue to resolve between the vehicles and anims branches and greatly benefit both in the end product.

Map Expansion. 
We generally don’t talk about map expansion until it’s ready to hit, but the next area will make full advantage of players being able to naturally spread out from their traditional urban starting points. There’ll also be vehicle-based locations we haven’t been able to feature before.

Other stuff! Two more items of note this week. First off, one of our bigger international player-bases can be found in Brazil – yet the PZ community translation for Brazilian-Portuguese has generally been ‘not brilliant’ and incomplete. As such we’re very pleased that a new version is imminent.

We’re also really excited to see the first mod appear on the workshop created through ItemZed (MilkMod!) and hope it’s the first of many. Our thanks to Thiosk for his feedback too.

Finally, we always knew that Spiffo was a badass but…

Here In My Car

Hey everyone! Welcome to Mondoid. This week, and we’ll cut straight to the chase with some video goodness! (Remember: work in progress, some bugs visible! More work in implementation and visuals to come!)

So, what are we looking at? Physics-enhanced vehicles in Project Zomboid, both online and off, and some hefty improvements on map streaming and object processing to handle it all. You enter a car with ‘E’, control with WSAD and have various vehicley-options open to you through a radial menu when you’re in the driver’s seat.

We’ve had the vehicles branch on the boil for a while (alongside the usual anims branch, standard build branches and a few others) but this year’s work in melding of EP’s car physics and framework with General Arcade’s special sauce has seen great things occurring. Progress has been good this past week too (as you can hopefully tell from comparing this video with one recorded five or six days ago) and we’re really excited about how the vehicles look and feel to drive. There have already been tests in multiplayer that went very well, with the new map streaming changes working niftily and boding well for future optimization.

So what’s still to be done amidst the general bug fixing? Well, in amongst others and the tidying up of zombie collision visuals – the following:

  • Firstly, and most importantly, we need to make sure that we’re not introducing a new breed of indestructo-tanks to Project Zomboid. We have to make sure that survival times aren’t hugely extended by cars, and that their use carries as many negatives as positives for the players. Also we need to figure out a good balance between zombie squashing fun and the realism Zomboid tends toward, avoiding the vehicles being too OP and sturdy against groups of zombies, while still providing the satisfaction of mowing down zombies in bigger vehicles.
  • There’s an issue to resolve with how cars are drawn into the scene, sometimes resulting in weird draw sorting bugs with ground grass or zombies drawn in front of the car when they should be blocked by it. This is due to the fact that currently 3D models are drawn at the same time as the tile they are ‘stood’ on. This doesn’t cater for larger 3D objects very well, so we’ll need to think on how to handle this and make sure they all occlude each other correctly.
  • The current sounds of the vehicles are 100% placeholder, and we’ll be working on these before release.
  • More cars! This video is fairly packed with ‘speciality’ vehicles, and Martin is currently in the process of making more vehicles to provide more variety and/or Kentucky normality.
  • Balancing: Each vehicle type needs balancing not only on their rarity, but in terms of handling, top speed, and all the other factors to make them feel different to drive. Right now, apart from their size and wheel positions, they are all functionally identical.
  • Wrecks and pile-ups: At the moment all cars spawn in parked locations, neatly parked in car parks or outside homes. We need to add wrecks, abandoned vehicles, pile ups and other more apocalyptic set ups of cars while also keeping in-touch with what Will’s set up in the PZ lore.

  • RingoD has patched up the faults in the TIS-curated community map Bedford Falls that were introduced through the 2x revolution. It should now be fully playable and can return to general PZ MP server use. Download here.
  • Turbo has updated his modding and dev tool ItemZed, along with some fresh easier-to-read instructions that explain how you too can play around with recipes, items, looting locations and lots lots more.
  • Mapper Cardenaglo’s crazy/awesome Gaia is out in its first form. Do check it out!

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
