Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We want to get lifeblocks into people’s hands sooner rather than later. By releasing in Early Access, we have more than just our small team contributing to and testing the game; we have a whole community. With everyone playing and sharing their thoughts, and being able to watch how people play, we can understand what players want from CHKN and make a better game.”

Approximately how long will this game be in Early Access?

“We want to make sure we incorporate player feedback as much as possible and leave Early Access only when the game is ready. Right now, we estimate version 1.0 will be done in mid 2017.”

How is the full version planned to differ from the Early Access version?

“To start, there will be improvements and additions to the current game. The world will get larger and more vibrant and varied, the creatures more intelligent and more useful with additional abilities, the survival gameplay deeper and more rewarding, the content and items more numerous, the UI cleaner and easier to use, and many other updates. But there will also be new features and gameplay added as well, like modding and scripting, additional creative tools, advanced creature training, alchemy, friendly NPCs, boss battles, sharing creatures with the community, and tons more. Plus all the great ideas, suggestions, and feedback we get from the community.

It’s tough to list everything here, so our roadmap is always available for a more comprehensive and updated look at what we have planned.

We should also mention that we don’t plan to stop at version 1.0. We have a lot of ideas for version 2.0 and beyond.”

What is the current state of the Early Access version?

“We consider the current Early Access version of CHKN to be in an early beta state. The game currently includes the core versions of Creative and Adventure modes for playing and testing, so you can build creatures using 150+ lifeblocks with 8 different abilities (more to come); give them basic commands; explore the tropical island biome (the first of 5); gather resources and craft them into basic items, tools, and structures; and defend against attacks. Our empathic intelligence AI is already at version 1.0 so creatures can actually learn, obey commands, express emotion, and develop relationships with the player, fellow creatures, and objects in the world.

All throughout Early Access, we’ll be updating regularly based on our roadmap and player feedback. We’ll have lots of new features and content, but we’ll also continue to improve on the current features, work on optimization and performance, and, of course, squash bugs.”

Will the game be priced differently during and after Early Access?

“Early Access pricing is currently discounted for those interested in joining us during development and to thank them for being with us from the beginning. Once the game is ready for release, with a full set of features and content, the discount will be removed. (Anyone who purchases CHKN at Early Access price will be automatically upgraded to the full version when it’s released.)”

How are you planning on involving the Community in your development process?

“We think of the community as our co-designers. We’re making CHKN together and love to hear from players about any aspect of the game.

Our Discussion Forums are open for feedback, constructive criticism, sharing ideas, bug reports, troubleshooting, or even if you just want to chat with fellow CHKN players. We check in on the boards regularly.

The development roadmap is always available for you to view and give feedback on, and you can comment and vote on what you’d like to see in the game.

We’re also available directly on Twitter, Facebook, or at to chat. Show us a crazy creature or share any YouTube videos you’ve made (we collect them!).”

[Patch Notes] v0.2.1: Bug Fixes & Improved Performance

Happy New Year, everyone. Thanks for all your feedback on the Adventure Update! We’ve got a new patch for you today full of optimizations, improvements, and bug fixes.

If you were having trouble with framerate (lag), loading times, or crashing specifically, this patch should help quite a bit.

NOTE: Folks on 32-bit operating systems who were getting “invalid platform” errors will now skip the error but will likely crash during loading. We’re still working on this! We hope to bring back 32-bit support soon. Until then, the previous version is available to play (v0.1.15)! Right-click on CHKN in your library, select “Properties”, go to the “Betas” tab, and select “previous” in the dropdown menu to download that version.

Here are the full patch notes...

  • Added terrain streaming to lower memory usage and increase frames per second
  • The Render Distance setting is now automatically selected based off of system memory. (You can set it higher manually if it’s not to your liking once you load the game. Just be sure you’re over minimum specs, otherwise you risk crashing!)
  • Launcher settings (Graphics Quality and Resolution) will now take priority over in-game settings
  • Improved “Stay” command to make a creature stays put in an area until commanded to do something else
  • Improved AI so creature will not move away as the player approaches to feed or pet it
  • Added a “Cancel” command to the whistle, which will stop creatures from performing the current action
  • Creatures that become untamed will no longer become aggressive immediately
  • Buckets now display interaction text based off of crosshair's target
  • Creature legs now animate backwards when walking backwards (no more moonwalking)
  • Death messages added
  • Default creature names added
  • Optimizations to item network syncing
  • Water and terrain culling added to increase performance
  • The tutorial starter creature can no longer be untamed or damaged while in the tutorial temple
  • Hoe tool degrades less quickly
  • Time spent on black screen during initial load significantly reduced
  • Fix to creature necks not animating correctly
  • Fix to creatures climbing trees
  • Fix to creatures walking through fences
  • Fix to invisible water trigger in temple
  • Fix to allow riding even if a creature is commanded to use a treadmill
  • Fix to bugs with multiple creatures using a treadmill that causes it to glitch out
  • Allow beams to be seen on all LOD levels
  • Fix to missing onboarding with the campfire
  • Fixed negative colliders on mirrored lifeblocks
  • Orb limit in creative mode is now unlimited as intended
  • Disallowed save game names with invalid characters
  • Fixes to save game corrupting bug with structures
  • Fixes to structures not displaying the right visuals on load
  • Fixes to structures not orientating correctly on load
  • Fixes to the stucco roof collider fracturing neighboring blocks
  • Fixes to not being able to pick up items with auto-pickup setting off
  • Changes to release unused memory when a chunk unloads
  • Fixes creature movement to slow down when approaching their target and slide less
  • Fix to workshops returning too many logs when canceling queue
  • Mill and treadmill animation/sounds now stop correctly when unloading
  • Sap no longer gives maple seeds
  • Cactus no longer edible
  • Temporarily removed the ability to open games to multiplayer since it’s incomplete (Coming back in the next version when it’s finished and working!)
We’ve got even more polish planned for the next build, and then it’s on to more new features and multiplayer. Until then, we hope you’re enjoying the Adventure Update! We’d love to hear your feedback.

Adventure Update v0.2.0!

It’s here! The Adventure Update (v0.2.0) is now released, just in time for the holidays. There’s still some work to do but we really want to get the update out to everyone and start getting your feedback on the new features.

You’ll find some build highlights and the full patch notes below. We’ve also added a link to our bug/known issues list for your reference. Onward!

What’s New
There are a LOT of improvements, updates, and brand new features in this build, with a big focus on Adventure Mode and creature interactions. Here are just a few of the highlights.

■ All New Map
Remember to bring a creature or two with you while exploring. You never know who you might run into.

■ Creature-Powered Structures
Put those creatures to work for you powering your homestead’s treadmills. (You only have to pay them in food.)

■ Survival Progression in Adventure Mode
Get stronger and build larger, more powerful creatures to take on more difficult challenges as you explore the island.

Here we see the rare three-headed dragon dance-fighting technique.

■ Creature Stat System
See your creature’s strengths and weaknesses as you build it! Experiment with different lifeblock combos to see what stats you get.

■ New Contextual Interactions and Prompts
Interact with your creatures and the world in different ways depending on what you’re holding. You’ll have your creatures eating out of the palm of your hand.

■ New Adventure Mode Starting Area
Make your way through the temple ruins to learn the ropes and build your first creature!

■ First-Person Hands, Items, and Animations
New items and use animations so you can see what you're holding when in first person view. Even the chickens are jumping for joy.

■ New Creature AI
Completely rewritten for more intelligent and emotionally responsive creatures... including scaredy cats.

■ New Whistle Command Radial Menu
Point and click, then select from a set of contextual actions. Your creature will take care of the rest.

■ New Creature Animation System
Better movement and improved performance! Everything an angry creature chasing you over uneven terrain could wish for.

■ Avatar Armor
Protect yourself and look snazzy at the same time. Your creatures are sure to be impressed by your fashion sense.

■ New Weather System
Poor soggy chicken. Maybe we should have made him his own house?

■ A Whole New UI
Menus, inventory, health and hunger meters -- everything’s been upgraded! See how your creatures are doing at a glance.

“Hey guys, I heard there were donuts over here?!”

There’s a lot more! For a full list of updates, you can check out the...

Patch Notes

  • Brand new environment: 5 unique biomes (tropical beach, forest, desert, swamp, volcanic) and points of interest to explore
  • New wild creature combos, with unique “mini-bosses” to challenge
  • New Adventure Mode intro experience (tutorial)
  • 4 mysterious temples added across the map (look for the beams of light to investigate!)
  • Magic eggs and lifeshaper relics added: unlock the ability to build more powerful creatures by finding the lifeshaper relics in Adventure Mode
  • New creature stat system: Important stats are displayed on screen while you build a creature
  • Creature-powered structures: craft building blocks and higher tiered items by putting your creatures to work
  • New whistle command radial system with contextual commands
  • First person hands, items, and animations for better immersion when using the first-person camera
  • New contextual interactivity system: available actions change depending on what you’re pointing at with the crosshair
  • Brand new UI/HUD throughout the game
  • Environmental effects for each biome added
  • Weather: relax on a rainy evening or find your way through the rolling fog
  • New, completely rewritten creature animation system for improved performance and visuals
  • AI completely rewritten for improved performance and more intelligent creatures
  • New pathfinding implementation: allows creature to accurately transverse structures and uneven ground
  • New tools added: like the club and hammer
  • Player armor added: craft new armor to protect yourself in the wild
  • All new food items added: like meatloaf, donuts, sushi and, of course, PIE
  • Procedurally generated trees: different types of trees found in different biomes for environmental variety; also provide new types of tree blocks when chopped down
  • New plants/foliage found around the island in different biomes
  • Game difficulty setting added: Explore in peace or challenge yourself by giving your enemies the advantage. Choose from “easy”, “normal”, or “hard”. Creative Mode defaults to “peaceful”.
  • Creatures now respect diet type: herbivore, carnivore, and omnivore; they will get sick if feed the wrong food type
  • Creatures that have been commanded to attack another creature will no longer eat the lifeblocks of their vanquished foe
  • Creatures will now automatically help break things: start chopping down a tree, for example, and your creature will come assist
  • Creatures can now pick items up in their mouths: they’re helping!
  • While building a creature, removed blocks no longer fall to the floor and need to be picked up; instead, blocks are magnetized to the player and picked up automatically
  • Cooking now requires a fuel source (like some wood) and time for the item to cook
  • Camp fire is now a low-level tool: can only cook low quality foods (get a furnace for higher quality cooking!)
  • Creature lifeblocks and tree blocks drop rate has been reduced in Adventure Mode for survival progression balance
  • Tamed creatures burn energy when using abilities
  • Breakable objects now regenerate “health” if left alone for a period of time: for example, your walls will “heal” up soon after you stop a raid on your homestead
  • Breakable objects now have a minimal attack value required to break them, and any damage that’s too weak will bounce off: for example, your fist doesn’t do enough damage to break an iron deposit; you’ll need to use a strong creature or craft a stronger tool
  • Drag/drop added to inventory
  • Improved flying speed
  • Off-hand slot improvements: now easier to use items in your left hand
  • World interactions reworked: now based on where the crosshair was placed when you first interacted to help prevent misclicks
  • Explicit “Rotate Block” key added when building/place (R)
  • Can't hurt tamed creatures while riding or if multiple valid hits
  • Tooltip descriptions added to all items
  • Partial controller support added and inputs cleaned up (NOTE: Only tested on Windows 10 with Xbox 360 controller so far. Please let us know if you test this out and have any feedback!)
  • Lifeblock values adjusted for progression
  • Structure block values adjusted for progression
  • Item values adjusted for progression
  • All new creature leg animations
  • Smoother chunk loading
  • Object pooling expanded to all objects in game to help improve chunk loads
  • Sound fall-off values tweaked
  • Tooltip now stays on screen near edges
  • Floating structure blocks fixed
  • Optimizations to many core systems

Known Issues
We’ve got a list of known bugs and issues over on our Trello board, and we’ve made it public so you can see them, too. If you encounter anything on the list, you’ll know that we’re working on it. If it’s not on the list, please let us know so we can investigate!

View the known issues list here.

Here are a few of the important ones we want to make sure you’re aware of:
  • For anyone on a computer with around 4GB of RAM (min specs), there will be some memory issues: lengthy black screen and slow loading at startup, and a lower framerate while playing. We recommend exiting any other big apps while you have CHKN running to help alleviate this. We’re looking into it!
  • Creature collision detection is still in progress, meaning that sometimes creatures collide with objects in the world (walk through a huge boulder, for example).
  • If you’re on a 32-bit OS, you may have noticed we increased the minimum requirements to 64-bit. This is temporary! We added a lot to this build and went over the limit, so we’re researching the best way to bring 32-bit back.
  • You may notice a change to the multiplayer menus. We’re in the process of adding Steam peer-to-peer networking with lobby support for the next update, but it’s unfinished at the moment. We recommend avoiding multiplayer for now!

Tell Us What You Think
We need your help to make CHKN better here in Early Access so please don’t hesitate to send your feedback along to us. We’re very happy to hear from you guys, whether you have comments to give, bugs to report, or just want to show off the stuff you’ve made.
  • Bug Reports: Submit bugs to this forum and we’ll take a look.
  • Feedback: Let us know what you think about CHKN, or post your ideas and suggestions.
  • Share: Tweet us @chkngame or upload your screenshots to Steam. We’d love to see what you create!


More to Come
We’re excited to share this update with you and we hope you like what we’ve added so far. We’re still hard at work on the known issues, as well as some other things we want to get into this update before we move on to the next one, so look out for another build in a few weeks.

Thanks, everyone!

- Team CHKN

P.S. A special note to our pre-release testers: Thanks for all your feedback and bug reports! We really appreciate all your help.

“The game was fun already, just making weird creatures, but now I can go around collecting resources and make my own creatures. [...] This game is awesome now. I can't wait to play more of it.”

“In CHKN, when you give life to a creature, it exists with its own set of needs, interests, and personal boundaries like a grotesque Tamagotchi. This factor is what makes CHKN truly stand out among its peers.”
Curse Gamepedia

“I actually really like the idea. [...] A world populated by tame-able creatures. I have mortal human instincts and a deep-seated fear of the unknown, especially when the unknown looks like somebody took The Known, ate it, and vomited up the parts.”

About This Game

CHKN is an open-world sandbox game where life itself is your strongest tool!

Create life, block by block…

Bring living, breathing creatures to life in any size, shape, or combination you can imagine. Whether you build tiny pets or enormous abominations, they’ll all have genuine personalities and feelings that respond to your actions and the world around them. One may be smiling at you, eager to be your new best friend, while another may snarling at you and giving you stink-eye. The latter has most likely decided that you look delicious, so maybe you should run?

Give your creatures unique traits and abilities…

Lifeblocks have different stats and abilities built into them. Some are strong, some are fast, some shoot blinding ink, some poison enemies…they can all be used to your advantage to make creatures more effective. A creature with a strong beak can chop down trees more quickly than you can. And you’ll definitely want a creature with a water-blast ability with you while you explore that dragon’s cave... unless you like being on fire?

Work with your creatures to scavenge, craft, and build…

Your creatures will help you gather resources in order to craft a wide array of tools, items, and structures. Collect unique lifeblocks to upgrade your creatures with new abilities. Build a homestead to protect them from thieving poachers. Start a farm to grow crops so you don’t go hungry. The better resources you have, the better the things you can craft, so you’ll need to scavenge if you like that whole “staying alive” thing.

Fight for survival as you explore a mysterious island…

The world around you is teeming with life, some friendly and some… not-so-friendly. You’ll need to work together with your creature companions to survive the many dangers of CHKN, avoid starvation, and defend your thriving homestead. There are three-headed dragons to fight and poachers to defeat. There are secret caves to explore, beaches to roam, and lush valleys to scavenge. There are also other, more mysterious things to discover but, you know, SPOILERS.

Get Creative…

If the risk and survival of Adventure Mode aren’t your thing, you can spend your time in Creative Mode. Here you’ll have an unlimited supply of every lifeblock and resource at your fingertips, so you can experiment and create whatever you like from the beginning with no restrictions. You won’t have to kill four dragons to see what it’s like to have a creature with 12 fire-breathing heads. (Hint: It’s pretty great.)

Help Us Make CHKN Great…

We’re just beginning with CHKN and we’d like to involve you in this journey as much as possible! Our development is completely open, so you can see what we’re working on, comment and vote on what you’d like to see added, and share your ideas with us in the discussion forums.

Thank you to all our CHKN fans for your feedback, bug reports, and suggestions so far!
