V3.1.0 Henpocalypse Experimental Update!

Posted on July 22nd, 2026 02:07 PM EST

The version 3.1.0 Henpocalypse Update is available now in experimental form on Steam only. The Stable version will come soon barring any critical bug fixes during the experimental phase. Read on for more details.

Here is how you participate:

  1. Right click on the game in steam

  2. Click on properties

  3. Click the “Game Versions & Betas” tab

  4. The drop down menu will have latest_experimental available <— you want THAT

  5. Select that and wait for the game to download

Important Notes about this Experimental Release:

  1. Sandbox Options for enemy and animal Density and Respawn rates have been split into day and night settings. Due to this change, please check your preset codes to make sure they are still valid. Invalid codes may default some or all settings. Official Presets have also been updated with this change in mind.

  2. A late localization update was made to the chicken coop input tooltip where chickens were mistakenly mentioned as an input value. The chicken coop does require chickens for production. A localization update for additional languages will come with a future update.

  3. Although new games will always be recommended, game saves should be compatible and a new game is not required. Don't forget that saves can be backed up with the Manage Saves function. Copy and name your save for future use.

The Henpocalypse V3.1.0 Update Release Notes

  • Chicken farming in the apocalypse is harder than it sounds. First you have to sneak up on the fowl. When that fails, give chase until you catch it. Then defend your raucous, fidgeting feathered friend from zombies all the way back to base. Place it in your Chicken Coop workstation for a steady supply of eggs and feathers. Rinse. Repeat. Now you're an apocalyptic chicken farmer.

  • The Chicken Coop includes three tool slots:

    • Brooding Lamp: Speeds up production and chicken maturation

    • Chicken Run: Lets chickens hunt for bugs, cutting feed cost by 50%

    • Nesting Box: Unlocks chicken breeding and adds nesting slots

  • Once you catch a chicken and add it to your Chicken Coop, you will need to feed it by crafting ‘Rekt’s Chicken Feed’ made from Corn and Rotting Flesh.

  • In addition to capturing and carrying chickens, a new Chicken Stress event mechanic has been added for flavor. By default, when your captured chicken reaches 100% stress, you drop your chicken and a special event is triggered based on your game stage. These new events range from dropping your chicken to angered zombies to angry chickens! A sandbox option is available to tune these events to your liking.

  • Along with the new Chicken Coop Workstation comes four new Chicken-Centric Recipes including:

    • Chicken Nuggets

      • Crafted from grilled meat, feathers, corn meal, and animal fat. Not only are the nuggets filling, they temporarily remove encumbrance.

    • Chicken Wings

      • Crafted from domesticated chickens, corn meal, eggs, oil, and honey. Grandpa’s favorite wings give you temporarily boosted melee damage and infection immunity.

    • Ash Chicken Stew

      • Crafted from domesticated chickens, mushrooms, corn, coal, and water. Comes with plenty of food, but has no smell to zombies.

    • Roadrunner Chicken Jerky

      • Crafted from domesticated chickens, yucca fruit, nitrate powder, and beer. A moderate amount of food that temporarily boosts your run speed, beep beep.

  • The Big Beak cosmetic outfit, originally worn by Nana’s Famous Chicken Mascot, is coming with the Stable release. Cluck and load. Cock-a-Doodle Doom.

  • We’ve added new Sandbox Settings and a QR Code feature! Now players can easily scan, copy, and share sandbox codes from their phones. Note: Existing custom presets may require updating with these new additions. New Sandbox Options: 

    • Chicken Coop Time - Speed of production

    • Chicken Coop Yield - Amount produced per cycle

    • Chicken Coop Input - Required feed amount per production cycle

    • Chicken Stress Event - Controls events when chickens get stressed

    • Density and Respawn rates have been split into day and night options

    • Density and Respawn types have been split into enemy and animal

    • Infection Chance - Controls chance to get infected

    • Hunger Multiplier - Rate of food consumption

    • Thirst Multiplier - Rate of water consumption

    • Stack Size Multiplier - Max size is capped at 30,000 for all items

  • We’ve added 4 new Loading Screen Images to the game replacing the old ones where the tooltips are displayed.
