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!”

Sway of Things

Hey all, here’s what’s happening.

Build 40 is for all intents of purposes done now, with one addition that might need a few fixes that we’ll explain the reasoning behind below.

On Tuesday we released Version 40.26 to the IWBUMS public beta. As we forecast last week, this contained:
  • New, rare, inventory clothing types to better insulate players.
  • Thunderclaps when players are banned on a server. (Optional)
  • Better admin control over weather effects
  • Fixed map bugs. Fixed missing vehicle skids sounds in MP. Fixed broken MP car locks. Fixed container bugs. Lots of other fixed bugs.
Being the first product of Bitbaboon Steve’s new internal autobuild system though, there were a few teething troubles that caused issues for our Linux server operators. Which has expedited the release of today’s Version 40.27. This contains remedies for annoying small tree collisions, and car battery fun.. but predominantly it contains the below.

We’re pretty happy with the fog, mist, storms, improved snow and other general additions of Build 40 – but something we weren’t 100% satisfied with was getting an indication of wind speed and direction across to the player. There just weren’t any indicators on-screen, and we weren’t making the most of a lot of the work on the simulated climate and weather systems. It was something of a blemish on an otherwise really cool feature. And so Turbo scurried off to his experimentation chamber and…

This is now playable on the IWBUMS beta, but will need some balance and feedback from testers as to how strong the effect should be at different wind speeds. We also, clearly, need to know if anyone notices any change in performance. Right now, trees sway slightly in low wind – and in storms, especially, at night they’re a bunch more atmospheric. (We’ll also be adding in better wind, and other, SFX in Build 40 patches.)

Through building this system into the game, Turbo has also unlocked some helpful visual niceties that the game has needed for a long time. They will also be of huge benefit to our players who are hard of hearing.  In this build, this includes:
  • Doors shaking when zombies hit them
  • Locked doors shaking when the player tries to open them
  • Trees shaking slightly when the player is chopping them down.
  • Trees rustling when the player, or zeds, walk through them
  • Trees shaking after car collisions
Please note, however, that in the current IWBUMS beta the bigger trees move too much in response to player/zed actions – and some of the SFX are a bit off. Here’s a compilation vid of the new feature:

Work continues with the TEA’s preparation for the entire team moving onto animations once 40 is final and patched, a lot of it under the bonnet kinda stuff. A big improvement to the animation system and tools is the ability to clone animation states and override aspects of them without needing to completely duplicate the state logic that drives it.

An example of this would be for handling (quite literally) weapons while walking, strafing or attacking. We can now define the core states for handling walking, strafing, sneaking, attacking without a weapon equipped, and then creating other states using that as a template that say hold a one handed weapon, or a gun, and substitute animations while still retaining all the logic tying together and blending the animations with the gameplay. Functionality such as this will speed up Animator Martin’s job of implementing all these states into PZ, and cut down the replication of work from the coders once we’re all inside the system.

  • We’d like to welcome ChrisW back to our bank of coders, who will be picking up where he left off with the Sims style cutaways we’d like to make internal building navigation a bit slicker.
  • As mentioned last week RJ is now working with Xeonyx, creator of New Denver, to help debug his new Hollywood Studio map and come up with an Official PZ Challenge system for it – for when it’s added to the main game. Here’s another screenie from it.

This week’s sunday service from KurtZ. 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.

Zombie, it’s cold outside

As mentioned in recent weeks, we’re now on clean-up duties before the release of Build 40 – which will then be patched with whatever’s necessary, before the animation branch being worked on by the guys over at TEA is fully merged into the main dev codebase for work on Build 41.

Last week, on IWBUMS beta 40.21, we put in the reflective windows skybox to better show season/day/night (and in prep for a future build’s reflective water), and also included Turbo’s more natural-looking snow, which can also be seen in the featured image above.

In the mean-time we’ve had several other test builds backstage, and are now putting out beta version 40.25. The full changelist can be found here, but the headlines are below.
  • Weather patterns are now more random, generally shorter, less intense in terms of screen darkness and have more periods of clear sky.
  • Cloud patterns seen on the ground have been updated, and have new textures – night has been improved.
  • Ground snow accumulation has been improved and updated, also working better when snow is turned on with admin/debug tools.
  • Weather periods can now also be fully modded, including a designated ‘modded’ stage which can be freely modified.
  • Insulation properties of different clothing now more clearly shown in the UI.
  • Spawns have been added for McCoy Logging and Fossoil vehicles, which weren’t appearing – alongside improved car spawns at gas stations in general.
  • Fixed: various chatbox and admin issues, a longstanding MP issue in which loot was respawning way too soon, the weird tile visual effect with some zombie corpses, crowds of zombies launching cars like bottle rockets (!) and players sometimes being trapped in their car (and zombies getting confused) by Yuri’s invisible anti-clip forcefield.

We will be holding an IWBUMS Community Megatest tonight to see how many major irritations remain, and to gather info on the login issues that hampered the last Megatest – should the same problem arise.

If you would like to join in then keep an eye on the TIS forums. Free PZ codes for participants will be available (usual conditions apply) but please note that this isn’t a stress test so the required player number on the server might be limited.

It’s been a busy week for TEA preparing for the code merge of the animation build into the mainline development branch as soon as build 40 goes final. They have completed the vast majority of the tasks required for the handoff, at which point they will continue to work on bits of extra technology to make the main animation build development go smoother, and end up with better results, while the rest of the team beavers away converting the main branch’s character states to use their new fancy state system.

TEA have implemented all the character control and combat features that were present in the early animation build, but with the new elegant and fast to implement data driven state logic that will act as example for the rest of the team to use as a basis, as well as being a much more robust and bug free base than what existed before, so we’re hoping that while it certainly won’t be a quick task, with the entire team pushing toward it we’re hoping progress will be swift, and we can finally start showing more exciting videos on the Thursdoids with the confidence that they are finally around the corner. Animations represent a huge amount of work as well as a linchpin for the rest of the major features to be implemented into the game. Each build after and including animations (intermediary quick builds aside) on our roadmap to 1.0 and filling in those missing features everyone has been waiting for (yes, those). It’s going to be an exciting 2019!

After the hand off, TEA will be looking at some extra tech, such as animation retargetting, which will not only mean a much easier time for modders to implement their own animations and models by allowing animations to be adapted to slightly differing skeletons, but will also save poor Martin many many hours of reexporting hundreds of animations whenever we decide to add a bone to the skeleton (looking at you, backpacks!). In addition, they are going to look into finally getting the proper rotation blending working nicely, which has been a thorn in our side since day 1, and would if nailed allow for better turning and much more immersive turning animations. Though obviously it’s key that we retain the nice responsive character movement, so we’ll need to experiment with how to allow for animated turning without the character feeling sluggish to control.

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:
  • Vehicles with full physics and deep and realistic gameplay mechanics.
  • 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!
