Here’s what’s new:

🧪 Research Lab & Bio Processing

Dead zombies aren’t going to waste anymore. They’re now part of your production line!

• Zombies that die during the night are now collected and stored in the Research Lab morgue

• From there, you can move them to the Resurrection Table and bring them back as controlled test subjects

• Revived zombies can be placed into special cages, and each zombie type generates unique special resources over time

• You can unlock multiple cages to speed up your resource production and build a proper bio-factory

• These resources can be:

  • Sold directly at base value

  • Or processed at the Lab crafting station into items like Gore Bait, Red Serum, or valuables like Alpha Cure for much higher profit

• All bio products can be sold through the new BioSell App on your computer, so you can manage the whole process from storage to sale in one place

🛡️ Upgradeable Barricades

Your defenses are no longer just throwaway planks.

• Barricades can now be upgraded through 3 tiers

• Each tier increases health and durability, making them last much longer against stronger waves

• You can transform a basic wooden board into a reinforced plank, and eventually into a sturdy metal barricade

• This gives you more control over how you build your defenses: light and cheap, or heavy and long-lasting

🔧 Bug Fixes & Improvements

• Fixed an issue where ammo items duplicated when they were left on the ground and the game was reloaded

• Fixed a bug where cleaning stains in the Chape l caused the player to lose energy instead of the employee

• Adjusted seed prices for better economic balance and progression

• Fixed an issue at the Urn Station that caused all urns in the same category to be consumed

• Fixed a bug where the courier sometimes failed to arrive at the Delivery Station

• Fixed an issue where employees were not loading correctly when entering the game

• Localization improvements and text fixes across multiple languages

As always, we’re continuing to work through your feedback, bug reports, and suggestions to make Zombie Graveyard Simulator smoother, deeper, and more fun to manage and defend.
