Bugfix Update #9 - Stuck Swarms, Immigrants Changes

[h2]Greetings, Survivors![/h2]

We have noticed an important issue with the previous build that caused some swarms to get stuck in the corners of the map. While this issue is fixed in this build, we want to let you know that it won't get rid of those "broken" infected that already exist in your current saves. If you notice large amounts of swarms stuck in your gameplay (and thus, impacting your performance) starting a new save might be the best option.

[h2]Changelog: [/h2]


  • The maximum number of immigrants joining the Zone at once has been reduced to 10,
  • The number of the infected in swarms has been adjusted to be even more dependent on the "hordes number" setting in the game customization,
  • Attacking with melee weapons from vehicles has been disabled,
  • An issue with swarms gathering in the corners of the map has been fixed,
  • An issue with an excessive number of vehicles spawning on expeditions has been fixed,
  • An issue with squad path visualization not being visible upon squad selection has been fixed,
  • An issue with the Research resume requiring additional scientific materials has been fixed.

After introducing Children, we noticed that the population growth was too steep when combined with the immigrant system. Hence the decision to reduce the maximum number of immigrants that can join your Zone at once. Other than that, we are further improving the Hordes Number customization option to ensure that players can really make this smooth transition to harder or easier difficulty, depending on their preferences.

Have fun!

Bugfix Update #8 - Additional Horde Multipliers, Expedition Issues

[h2]Greetings, Survivors![/h2]

This time we are coming back to you with a minor update, which addresses the most recent issues with expeditions and allows for better customization of your games. We hope that with the new horde modifiers, you will be able to tailor the gameplay accordingly to your needs!

[h2]Changelog[/h2]
  • New Horde Multipliers have been added to the Game Customization - x0.4 and x1.6. Use it to change the amount of the infected to your liking. You can also change that in your current savegames, via "Customize" in the Esc Menu.
  • The number of resources on the expeditions has been readjusted and should correspond to the real building volume in that location.
  • The number of gun POIs on the Washington recommended map has been increased.
  • An issue that resulted in some hordes not being visible on the expeditions has been fixed.
  • An issue with squads taking incorrect paths through expeditions has been fixed.
  • An issue with the Map Info Panel displaying incorrect temperature ranges has been fixed.

Bugfix Update #7 - Further optimisation and balancing

[h2]Greetings, Survivors![/h2]

We are pleased to deliver another important batch of fixes - v0.24.8.7 11 BETA is now available at the default branch - make sure you update the game!

First of all, we changed our entire compilation infrastructure, to build a more stable game that will work much more smoothly and crash less often.

However, we have an important message to all 3% of you who try to use integrated graphics cards:
Infection Free Zone cannot work properly with integrated graphics cards. The game is simply too complex, there are usually way too many dynamic 3D objects and the pathfinding grid is too large for the older generation of machines. IFZ might look aesthetically old-school, but it is actually extremely computation-heavy.

[h2]Changelog: [/h2]
  • The HPs of the adapted buildings have been increased based on their size.
  • The amount of hordes, immigrants, and bandits that we encounter will now be affected by the total volume of the buildings on the map, rather than the total number of buildings on the map.
  • Beverages now need 2x less grain


[h2]Bugfixes: [/h2]
  • New animations for hitting the infected with a vehicle have been added.
  • An issue with some buildings not completing adaptation after reaching 100% has been fixed.
  • An issue with the mood modifier from kindergartens being too low for loaded games has been fixed.
  • An issue with production not starting in very small buildings has been fixed.
  • An issue that made it impossible to disband a squad after replenishing has been fixed.
  • An issue with some resources on expeditions being unavailable when saving the game has been fixed.
  • An issue with the adapted buildings losing green filling during winter nights has been fixed.
  • An issue with the barn event not appearing for some players has been fixed.
  • Another set of small changes aimed at improving optimization has been released.
  • An issue with some maps crashing after launch has been fixed.
  • An issue with some buildings losing mouseover highlights has been fixed.

  • An issue with the squad groups assigned to numbers not being saved has been fixed.

  • An issue with the game freezing when picking up the resources from the ground has been fixed,

  • An issue with the building's HP not increasing properly when progressing the partial adaptation has been fixed,
  • An issue that resulted with "Create Squad" button not selecting the best fit members for the squad has been fixed,
  • Several events have been updated to improve the stability of the whole event system.
  • The LOD system has been updated to improve the performance of the game,
  • An issue with some saves returning the "The Zone has fallen" message has been fixed,
  • An issue with exiting the exchange sometimes returning errors has been fixed,
  • An issue with some hordes burying underground in the water has been fixed,
  • An issue that resulted in all the hordes in the swarm having exactly one infected has been fixed,
  • An issue with some infected staying outside the buildings has been fixed,
  • An issue with production progress being cancelled at sunset has been fixed,
  • An issue with unresponsive icons for the deconstructed buildings has been fixed.
