First and foremost, a massive thank you to each and every one of you for your invaluable feedback. We've been closely listening to your experiences and suggestions, and as a result, before the next major patch, we're rolling out further balance changes in this minor patch to address your major concern – faction reputation balance.




Balance



  • Reputation gains from daily quests have been significantly increased.

Gameplay



  • Starting reputations for both the Crimson Corp and Green Army factions have been adjusted. Players will now begin with a "Cautious" relationship status with these factions, a shift from the previously "Hostile" status.
  • Minor rebalancing of reputation requirements of some trader items to ensure a more balanced trading experience after above change.


Bug Fixes



  • Fixed multiple issues related to rare cases of item disappearing.
  • Addressed a rare crash scenario to enhance game stability.

As always, your insights play a crucial role in our continuous efforts to refine and improve ZERO Sievert. Let us know your feedback so we can continue to evolve and expand the world of ZERO Sievert. We're also excited to give you a sneak peek into what's on the horizon. Stay tuned for our next dev blog where we'll delve into the throwables set to debut in our upcoming major update. The exact date is still TBD, but we promise it's something you won't want to miss!

Thank you for being a part of our community, and as always, happy hunting! 🎮

Beta Branch for Patch 0.31.29



Hunters,

Patch 0.31.29 Beta Branch is now available!

We are aware that a minority of players are still having issues with their savegame being wiped each time they start the game. We have nailed it down to a Steam cloud save related issue, and we're launching a new beta branch, version 0.31.29, to try to tackle this matter. This patch is specifically aimed at players who are experiencing Steam Cloud save issues (e.g., save gets deleted each time they launch the game). If you are not experiencing the above-mentioned issues, you do not have to update.

As always, we're committed to acting on your feedback. Please keep sharing your thoughts; we're truly grateful for every perspective you bring to the table!


Opt-In Steps



  • Right Click on ZERO Sievert in your Steam library.
  • Choose "Properties."
  • Select the "Betas" tab.
  • Choose "public-beta - 0.31.29" from the dropdown menu.
  • Your game should auto-update to 0.31.29.

Adding Launch Options



In order to help us fix this issue, we kindly ask you to turn on the below launch options, and send the generated log either to @ericd on our Discord, or to eric@modernwolf.net.


Options
"-log_to_file": Writes debug log information to a text file found in %LOCALAPPDATA%\ZERO_Sievert\ (e.g C:\Users\YourUserName\AppData\Local\ZERO_Sievert) and is named with a timestamp, like 2023-7-20_10-58-31.log
"-strict_cloud": Adds extra behaviour checks for Steam Cloud issues.

How to Add Launch Options



  • Right-click on ZERO Sievert in your Steam library.
  • Choose properties.

Developer Update 2023 Vol.7 - A Look Back at Patch 0.31



Hello Hunters,

As we traverse the fascinating world of ZERO Sievert, we feel it's important to reflect on our recent journey, particularly the roll-out of patch 0.31.

Patch 0.31 was a significant milestone for us, bringing in ambitious changes to our codebase, data storage methods, new questlines, and an overhauled faction relation system. However, like any big adventure, there were unexpected challenges along the way.

The transition to patch 0.31 wasn't as smooth as we had hoped, and for that, we sincerely apologise. The patch, unfortunately, introduced more bugs than we anticipated, causing disruptions and some moments of frustration for you, our dedicated Hunters. To stabilise the game and address the most critical issues, we rolled out four hotfixes / patches in quick succession. While these fixes were largely successful, we acknowledge that with each hotfix, a couple of new bugs slipped through the cracks. We take full responsibility for these hiccups and are immensely grateful for your patience and understanding during this time.

The lessons we've learned from this experience are invaluable. The core challenges stemmed from how we approached the testing process for new patches on older save files — it wasn't as comprehensive as it needed to be. Moving forward, we're taking tangible steps to bolster our testing procedures. Not only are we implementing additional safeguards to reduce the chances of such issues recurring, like we did for the latest patch, but we are also initiating small-scale player testing sessions. where a small group of players may have access to new content for testing purposes. For those interested in being a part of this initiative, please DM me (@ericd) on Discord. Moreover, if there are significant design changes in a patch, like with patch 0.31, we will be utilising more open beta testings. This collaborative approach ensures that we can jointly craft a game experience that resonates with all of you.

Your unwavering support, patience, and especially constructive feedback have fuelled our resolve to face and overcome each challenge head-on. As we learn and grow from these experiences, it's your belief in us and commitment to ZERO Sievert that keeps our mission strong. It's you, our extraordinary community, who propels us forward despite setbacks.

Thank you for being a part of this adventure - we can't wait to share with you what we've been working on next.

Happy Hunting!

P.S,
We've secured a nomination for the "Best Game" at the prestigious 2023 GameMaker Awards! 🏆

This recognition is a testament to the dedication and passion of our wonderful community. As we bask in this moment, we humbly ask for your support to clinch the title. Lend your voice and cast your vote for Green Army ZERO Sievert!

New feature for future bug Investigation



To aid us in further improving the game and fixing bugs in the future, we've added a new feature: launch options. When we are having difficulties reproducing a bug you have reported, we may reach out and ask you to provide us a log file generated this way, we thank you in advance, hunters.

-log_to_file: This option will write a lot of debug log information to a text file on disk. This text file is found in %LOCALAPPDATA%\ZERO_Sievert\ (e.g C:\Users\YourUserName\AppData\Local\ZERO_Sievert) and is named with a timestamp, like 2023-7-20_10-58-31.log. We can use information in this file to help us diagnose many problems.

-strict_cloud: This option will add extra behaviour checks. If anything goes wrong whilst initialising Steam or when writing to Steam Cloud then you will get a pop-up message.

How to add launch options



  1. Right-click on ZERO Sievert in your Steam library
  2. Choose properties
  3. Under the general tab, input -log_to_file or -strict_cloud into the text box of "Launch Options"

Looking forward, we're working diligently on another hotfix that will deliver more fixes next week. If you're still experiencing issues, please continue to let us know. Your input is crucial for improving ZERO Sievert.

Again, a big thank you to all of you for your patience, feedback, and bug reports. We're committed to making ZERO Sievert the best game it can be!

Update 0.31 | Patch Notes



Hunters,

Thank you for your patience and understanding in the leadup to this patch. Update 0.31 not only brings exciting enhancements to ZERO Sievert, but it also lays the groundwork for more thrilling updates in the future. In this patch we are excited to bring you deeper connections to the in-game factions. Choose your allegiance wisely - will it be the formidable Green Army or the lucrative Crimson Corporation? Discover new quests, daily challenges and more!

As previously discussed in our dev blogs, this patch comes with a save wipe. To go alongside the save wipe, we've introduced a new save file system and numerous quality of life (QoL) improvements. We understand some players may wish to continue their journeys on their old saves, for those players, we're launching the Legacy branch today, which you can easily access from your library.

We hope you enjoy this patch, and as always, let us know all your feedback on our Discord channel (or here!).

Happy hunting!




Major Update 0.31 Patchnotes



Save Wipe



A new game is required for this build. The content of old save files will *not* be migrated to the new save file format.

However, if you wish to continue your current life in Zakov, you can select the legacy build (0.30) from the Beta tab. Here are the detailed steps to do so:

  • Right Click on ZERO Sievert in your Steam library.
  • Choose "Properties".
  • Select "Betas" tab.
  • Choose "Legacy - Build 0.30" from the dropdown menu.
  • Your game should auto update to previous version for you to continue your old save.

Modding



  • The Mod.ini file is no longer supported due to changes in the way weapons and items are stored in the backend, and that we have implemented a more powerful replacement.

    Dev notes to modders:
    Changing Existing Data
    Mod.ini is no longer supported in ZERO Sievert. Instead, we've implemented a powerful replacement! Most of ZS's game data is now stored in external JSON files, instead of being concealed within the game's code. This gives you the opportunity to adjust many different variables and values that were previously inaccessible. Not only can you alter weapon names, but you can also adjust their damage, bullet speed, magazine capacity, and almost everything else. JSON files are essentially text files that store data in a specific format, which can be edited with any text editor. However, you may need to tell your OS to open the .json file extension with a suitable program. JSON can be a bit fussy, so make sure you validate your JSON after editing, using an online tool, and always save in UTF-8 encoding.

    You can find the new database files in the game's install directory (via Steam, right-click on ZERO Sievert in your library, then select "Manage" then "Browse Local Files"). The game's base data can be found in the /ZS_vanilla/gamedata directory. There, you'll find many JSON files, covering everything from ammunition to weapon mods, to chest loot tables, to NPCs. Feel free to modify these files as you wish. For example, if we wanted to rename the Nozin Makant to the solemn and respectful "Igor4eva," we would simply open up weapon.json, search for "Nozin Makant," change the name, and save the text editor. Upon running the game, the new game data is loaded, and the Nozin's name will be different. If you wish to truly honor Igor's memory, you might want to boost the Nozin's damage - though tread carefully because this change will also affect enemies. Unfortunately, you can't change game data while the game is running, so make sure to check your work before launching the game!

    Creating Something New
    If you're looking to add something entirely new to the game, inserting it into the existing JSON files might be a bit challenging. You might have noticed a JSON file called gamedata_order.json in the install directory (and in the "ZS_vanilla" directory too). This file controls the location of JSON files and the order they are loaded into the game. Usually, gamedata_order.json uses relative paths. If you wish to add a new model of the BB 19 MOOSE, let's say a .45 ACP variant, you can create a new JSON file with only that item and then point to that JSON by adding a new file path to gamedata_order.json in the install directory.

    Extra notes and limitations
    Please be aware that if you modify files inside the Steam directory, they will fail Steam's file integrity check, and your modifications may be lost upon reinstalling. To avoid this, we've made it possible to store mod files elsewhere on your computer to prevent them from being overwritten. As mentioned, gamedata_order.json usually uses a relative path to find JSON files, but it can also accept an absolute path. We highly recommend storing your mod files in a static location on your hard drive to prevent accidental loss.

    There are a few limitations currently, however. NPC behavior and quest logic are not exposed, and many internal strings in the game are not available for editing either. At the moment, it's also not possible to change item or bullet graphics, which we know is a feature many of you are eagerly waiting for. Implementing dynamic graphics, audio, and logic into our engine in an efficient manner is a complex task that we don't want to rush.

    That's all from us for now. Over to you! We hope you enjoy experimenting with the core mechanics of ZERO Sievert!




Cloud Save


Cloud save is now enabled for ZERO Sievert, which means you can now sync your save data across multiple platforms. However, please note that if you are in the middle of a raid on one platform and start another session on a second platform, your raid progress won't be saved, as there are no saves or checkpoints mid-raid.

  • Cloud Save feature now added to the game.
  • An option to DELETE CLOUD SAVES is now available in the settings. Please use this function with caution, as it will permanently delete all your save files, as indicated by its title.


Faction Relations & New Questline



  • You can now join the Green Army or the Crimson Corporation once you grow your reputation among the factions.
  • Completing main quests and daily quests will increase the reputation with that faction.
  • Daily quests given by the Networker NPC are now separated based on the different factions.
  • Added new quests and tweaks to existing quest.
  • Items sold by the trader of a faction now require a minimum amount of reputation with that faction to be bought.
  • Members of either the Green Army or Crimson Corporation will have access to exclusive quests as part of the chosen faction.
  • Each faction will have their own daily quest, including Loner and Scientist factions.
  • You will lose reputation with a faction in two ways:
    - When you shoot the first bullet to an NPC of a faction
    - When you actually kills an NPC




  • The game will now pause automatically when the window loses focus.
