Indoor Movement

We see that some of you are wondering what we are working on at the moment. While some things are still in the early conceptual phase, today we would like to show you the Indoor Movement. This system is intended to solve some problems currently occurring. Among other things, it should help with the defense of very large buildings.

Don't worry, the issue with the building flashing white will be fixed in the future. This is just an early prototype of this feature. Still, we remain extremely excited about this change! Let us know what you think about Indoor Movement and all the recent changes in the comments. And what's most important - have fun, survivors!

Major Update #1 – Gear, Citizen Reproduction, Greenhouses, Tree Regrowth June 6


Greetings Survivors

We are super happy to let you know that a new Major Update is available on the Default branch of the game! At first, our initial focus after the launch was to solve as many bugs and stability issues as possible. After a few updates, we reached a point where the number of stability and bug reports decreased by 90%. Instead, numerous requests for new functionalities and content began to appear.
In this Major Update, we want to meet those expectations. We are adding several new systems and hope that they improve your overall experience with Infection Free Zone. Have fun!


New Features and Content

  • Gear System has been added to the game, including Sport Protector, Riot Gear and Plate Armor. Those will allow extra protection for your squad members.
  • Two new types of POI have been added - Museums and Sports Shops where you can find the Gear.
  • Emblem customization has been added. Now you can both change your zone's name and its emblem. It's also possible to upload custom images to the Infection Free Zone_Data\StreamingAssets\Emblem\Logo folder and use them as emblems in the game.
  • A tree regrowth system has been added. The trees will grow back by themself now.
  • Greenhouses have been added to the game. They cost 4 wood, 8 metal, and 1 tool to build, but are immune to negative modifiers from the weather.
  • The Citizen Reproduction System has been added. When specific conditions are met (enough food, available housing, proper mood level), children will appear in the Zone. Children consume 50% as much as adults, use the house/shelter living slots, and take 12 in-game days to grow up.
  • A resource discard feature has been added (right-click on the resource in your storage to discard the resources).
  • Additional entrances have been added to the buildings to improve the overall scavenging experience.
  • A new Megastorm and Supermoon music themes have been added.
  • The Citizen Housing logic has been reworked. The citizens will now get back to sleep at the closest shelter/house, which should help with running outposts.
  • The Building System has been improved to allow structures to be placed on gatherable objects. The workers will remove the gatherable object first and then proceed with the original task.
  • POI Filters have been added to the View Layers section. Players can now look for specific POIs like guns or gear on the map.
  • Heavy Rain animation for the Megastorm event has been added.
  • New shrub models have been added to the game.
  • Damaged structure models have been added to the game,
  • Snow particles and snow animation have been updated.
  • Beijing Map has been updated.
  • Mast visuals have been updated.
  • It is now possible to select an empty production cycle in the Medbay building to keep on attending to the wounded in the beds but refrain from manufacturing unwanted first aid kits. The UI of this solution will receive an update in the future.


Balance changes

  • The day/night length has been increased by 20%.
  • Default Warehouse capacity has been increased by 20%.
  • The number of potential immigrants wandering around our Zone has been slightly increased.
  • The Globetrotter achievement logic has been updated.
  • Hordes will now attack the encountered farm crops. Farms won't get destroyed, but the production progress will go down.
  • Biome regions have been updated to fix issues with excessively low temperatures in some areas.
  • The Assault Rifle base damage has been decreased by around 50%, but the attack speed has been vastly increased. This should result in the weapon being very strong, but consuming significant amounts of ammo.
  • The Shotgun base damage has been increased by around 25%. The attack speed has been slightly decreased.
  • The Shotguns have been added to the pool of scavengable items in the game.
  • The maximum available angle when placing walls has been increased.
  • The maximum available camera zoom-in has been increased.
  • The camera angle change during zoom-in and zoom-out has been readjusted.
  • The density of trees has been increased.


Bug Fixes

  • An issue with tooltips displaying incorrect information for buildings that are unlocked by multiple technologies has been fixed.
  • An issue with hordes attacking structures resetting their position upon death of one of the infected has been fixed.
  • An issue with the military medbay storyline causing errors has been fixed.
  • An issue with non-infected NPC groups attacking Infected who were buried down has been fixed.
  • An issue that caused the Research Tree to not properly refresh all the available researches has been fixed.
  • An issue with errors happening with partially adapted buildings getting fully adapted has been fixed.
  • Issues that were caused by the Zone name not having a character limit have been fixed. Now the maximum character limit for the Zone name is 32 characters.
  • A number of other minor issues have been fixed.


We hope that you will enjoy all the recent changes. Have fun and let us know about your feedback in the comments! Would you like us to work further on the current systems? Or should we prioritize completely new functionalities? We're all ears!
Thank you for playing Infection Free Zone.
Best regards,
Jutsu Games Team

Other than that, we track all the reviews and feedback to decide on the other changes that should come to the game first. Dealing with bug fixes and performance is of the highest importance for us right now. Thank you for playing Infection Free Zone.
