Project Zomboid is an open-ended zombie-infested sandbox. It asks one simple question – how will you die? Whether surviving in Knox County free-roam or controlling Indie Stone mascot Baldspot in his quest to save his injured wife Kate – death is always a certainty. Quite how long you manage to put it off is another matter…

Its not just Zombies that will kill but the environment. You can build and fortify to keep the horde at bay or always be on the move. Fight the cold during winter. Farm to spend less time making risky supply runs. Make to much noise with firearms and zombies will be attracted to your location, forming groups organically making it difficult to fight them off or pass by unnoticed. Over exert yourself and you might not be able to make a run for it when it counts. Depression, starvation, loneliness, illness, insanity, a lethal bite...

Q: What to expect from v1? Whats the ETA?

Ladies and gentlemen, boys and girls, the first Build 33 IWBUMS public test has begun! To participate the please read the contents of this forum post very closely indeed.

This is a public test, and there will be almost certainly be bugs and peculiarities in the build as we expose it to a wider audience. To help us keep up, then, you’ll find that our bug tracker lives here.

We especially need difficulty and balancing feedback from this release, as it’s the first outing for our revamped New Game scenario and difficulty list. On top of that, please keep an eye out for spelling and grammar mistakes in the new TV and radio broadcasts – providing screenshots of erroneous lines of dialogue where possible.

The top line is: new FMOD sound system and music integration, furniture movement, herbalist trait, full MP radio broadcast system and multi-channel narrative content on both TV and radio, randomised house and item house condition as you explore and an improved MP server selection screen. Amidst other cool stuff.

There’s also a fair bit more to be dropped into the build when we’re a few versions down the line, alongside Creative Mode, that still needs a bit of polish and/or player feedback on the systems they build on. So we’re talking stuff like FMOD balancing and its impact on far/distant noise like thunder, the ability to move multi-tile items in the new furniture movement system, the ability to record/playback on in-world devices… all that fun stuff.

Anyway, here you are. Have fun!

Changelist: The official changelist for the Build 33 Public IWBUMS test can also be found here,

Bear in mind that not everything is done yet, still poking fmod and difficulty probably need balancing. This build does not contain Creative, which will drop into a future IWBUMS before 33's release.
I'm also aware of some bugs, I'll prob try to do a new version tomorrow with fixes.

When you post a problem with sound balancing, please say if you're on headphones or not, so I can balance them more easily, thanks! :)

There will be no dedicated server today, we need to fix a few problems before we can upload it. For now it's a single player only, we'll look to patch it in the next few days.

So, what's up?

  • FMOD: New sound engine! (more info on FMOD here)
    • Tons of new sounds and ambient! (fridge buzz, water drip, birds...)
    • New random music algorythm: some weird music will start at night to give a creepy ambient!
    • Proper 3D sound!
    • Added an ambient volume slider in the option.
  • New randomized buildings:
    • Some buildings will now be burnt, looted or already barricaded.
    • Some will have specific professions loots
    • Made world more alive, some windows/inside door will be open.
  • New main menu!
    • Allowing to custom your difficulty settings easier.
    • You can choose a difficulty for the world/zombie and then for your starter/character. (need more balancing)
    • Choose from "The First Day" to "6 Months After the Apocalypse" (hard early game), and don't forget our hardcore Survival (hard late game!)
    • Then select if your character will start with some bonuses, such as items or xp multiplier!
  • Radio/TV from Turbo and Will! (I'm sure they'll write more here soon ;))
  • Also from Turbo: moveable furnitures!
  • New trait: herbalist
    • With this trait you can find medicinal herbs by foraging.
    • They'll help you fixing your broken bones, your stomach disease, etc.
    • Some will require to be transformed in poultice with a mortar and a pilon!
    • Now each new game a random berry/mushroom (yay mushroom!) will be poisonous, same for multiplayer and only the herbalist will know which one you shouldn't eat. Not a herbalist? Take care when eating berries ;)
  • Few more stuff including bug fixing (such as crafting UI crash...), more info there tomorrow as I'm finishing another build... :P
  • Balanced zombies grouping a bit, start game should be way more easier (no zombies thumping at your door when you spawn, less zombies around you, etc...)

23/11 Monday Fix:

Hello survivors! A bit of a ‘getting on with it’ Mondoid this week as, as you can expect, we’re all busy bees working on the latest IWBUMS.


In case you were barricaded under a rock you’ll knoe that we’re currently in the midst of a test of a (still incomplete) build 33 on our I Will Backup My Save branch, and as expected work continues on both fixing up what is currently in the IWBUMS branch, with Will working on getting the initial infection TV and Radio into the game, as well as bug fixing those pesky typos and other bugs. Turbo is fixing up the issues that have been reported with the furniture moving system. Meanwhile RJ has been continuing with the sound system fixes. Here’s a few words from RJ himself on his build 33 stuff:

“Build 33 is on his way on our IWBUMS branch, we released a patch already so we’re on 33.1! Bugs still exist, but it’s mostly balancing the new sound engine and difficulty.

Some report that Survival is way too hard, still need to know if it’s REALLY too hard or it’s just people having bad luck or not skilled enough to play Survival (which is meant to be hardcore :D), but for those people, the normal mode should be ok!

So this is a hard piece to balance, but it’s progressing!

About sound, it’s the same, I balanced them a lot, made the reverb better outside, but still need to work on it so it doesn’t feel like your under a big metal dome!

Annnnd I also hear you “what about Steam Server update!” Well, I’m on it too, I fixed some bugs for multiplayer caused by the new sound engine, and I’m trying to get that steam server working, it’ll be probably for this week, maybe tomorrow with some luck!

In the meantime I may release another patch with bug fixes/balance, it’ll depend how well the Steam Server bugs are progressing…

So it’s getting there, build looks pretty solid so far and I think we’ll have bug fixed rather soon for a public release!”


We’ve still got a bit of finishing off to do on the new Creative Mode systems. The latest addition was a virtual object system which allows for tbx, tmx or clippings, as well as road segments, instead of being placed permanently within squares on the map, instead to be made into virtual objects which are placed on the map, but do not destroy the tiles they are placed on, only override them while the object exists in that place. This means they will remain an moveable object you can drag around without permanently distubing what goes underneath.

The original reason for this feature was to make the creation of road networks much easier, as it opens up the ability to have simple nodes that connect to eachother, and to form the actual tiles of the road and pavement virtually, calculated over the top of the base game map data. These can then be tweaked and changed as the map is expanded without having to clear out areas of the map. There would be of course a performance hit incurred due to lots of these virtual objects, so at some point these will need to be turned into permanent things on the map, and how that happens has yet to be decided. Either players / servers will have the option of committing these elements permanently to the map once the creators are satisfied with them, or maybe when the player runs sufficiently away from the object so that it streams out, it’s not clear which is the best option for simplicity / performance.

The roads are the pretty much last thing to get right, apart from a few fixes for making sure everything works on multiplayer, before Creative could be added to the IWBUMs.

Considering buying, just wondering that if I buy the Desura version then I can update it from that site mentioned here (indiestone)?
Just not sure, seeing a lot about people missing updates. Never used Desura either, Zomboid would be the first game so far I'd get it with.

Would the game need Desura to run? So could transfer/install it onto another computer without Desura? Not that installing desura would be a problem though, more familiar with Steam and games requiring that just to run.

And is the purchase, technically the full game price, as in, buy it now, and all future updates and releases are free access?

its not missing updates there just havent been any for way over a year now, they are still blogging and saying they are working on a new build but we've seen very little of this outside of a few 2 min vids and some blogs.

youll get the fanboys leaping to their defence but they have no more knowledge of the development than anyone else outside the Dev team.

so if you looking for a finished product then this isnt it but if you looking for something that may or may not be finished then this is the the half game for you, alternativly I also recommend the dead linger the devs put out very regular updates and are active and friendly and will answer any questions you have about the product not just "we dont give dates" like this lot at PZ development

TheRedBoar Feb 20 2013 replied:

yes because you need to activate it on desura. The only way to play the game is use the cd key desura gives you.

It has more info on this link:

And Desura is like steam. But for the game you dont need desura to play just the CDkey provided.

Download the latest version and it prompts you to enter cdkey and it lets you play there.

and yes it seems like there continually making updates for the game so its pay now and dont worry about later. Here is a legal notice I jsut saw on the link I posted.

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 (this applies to PC, Mac and Linux desktop only and not any potential future sequels or offshoots related to the game.) of Project Zomboid and we intend to support it for many years to come. However we are not legally bound to provide additional updates, and you are paying for the product as it stands now.

Your part about updates is very misleading they havent made an update to the desura version since september 2011 and no updates at all for the 2.5 adn wont be updating until the release of 3.0 which has no ETA/Release date or no vid footage

This is the date of the last update for the desura version copied and pasted from the changelog: Sep 7 2011, 3:46pm - VERSION: 0.1.5d

So far so awesome. Keep up the good work. I am pumped to be playing your final version of this. Even as it stands, it is really great. Sure there's hick-ups every so often (like all levels above the first becoming flat where you can't see anything on it (walls, yourself and interactive objects) or interact with, starting the game suspended in air, getting damage from absolutely nothing and dying from it).
My only tiff is not being able to find an axe, its like rare as hell and really important for building up some form of fortification and taking down walls. Besides that, it's really fun.
A question, can you die from boredom?
Will there be a way to make your own nails? Because I can see that if you uise the farm mod which provides endless amounts of food, an axe for cutting wood so you can make and use walls and boards with a hammer and nails, you could almost survive indefinite - could being the word as zombies love to roam, and it's easy to draw attention to yourself. The farms don't tend to themselves hahaha.
I am actually greatful there is no play limit like most other zombie games, -survive x days and be rescued or die-. They tend to be rediculously short and are usually restricted where you can hole up and how.

So are you downlaoding the most current version in the link I sent?

Most current one is 0.2.0r RC2.

There isnt a way to update. This isnt steam. There are no patches. You download the game again. You dont update the game.

So the most current version is unstable but has more content.

This is one of those examples of how great indie alpha funding can be... Project Zomboid is a real work of love fueled by a great community and great interaction between developers and fans. Even if it's just in the earliest stages the colossal potential it has for modding alone makes this a game full of potential. As for the game itself it has great music, and awesome atmosphere... It's a great ride for all the nostalgic gamers that fondly remember isometric games. And the structure of this game…

I enjoyed this game for a while, but due to the constant "patch coming soon" but never actually coming, im giving up on this game for now, maybe the game will finally be slightly updated within a year.
