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!).”

New Graphics Rendering: Pre-Release Sneak Peek

Check out the awesome new lighting and rendering overhaul we just added to Pre-Release! This change is step one to upgrade CHKN’s graphics and look & feel. We’re still tweaking so please let us know your feedback, We think it looks pretty dang snazzy already so we wanted to share it with you first! (Click the screenshots below to see larger versions.)

Left is today’s game. Right is on Pre-Release. Note the lighting now has better detail (see horns) and sky is atmospheric (haze, clouds).

Venus flytrap in a new forest scene on Pre-Release (right). Fog effects plus color correction allows for warm night time atmosphere. Note the improved light reflecting off the eyes.

To the desert! The new skybox is in full effect (on right). The sunlight is scattered and reflected nicely off the beetle mouth... right before it bites your face.

Here are the technical details, if you’re into that sort of thing:
  • Upgraded Visuals (Lighting, Colors, Rendering and Effects):
    • Switched lighting from gamma to linear model to produce much more accurate and realistic lighting
    • Switched from LDR to HDR rendering to produce more accurate colors and better shader effects
    • Upgraded skybox to a new dynamic system for better day/night cycle lighting, atmospheric scattering, advanced fog, and dynamic animated clouds
    • Added new post processing effects to tie it all together (color grading, motion blur, ambient occlusion, bloom, screen space reflection)

In the swamp, the mist is enhanced by the new scattering and height-based fogs. Add the color correction with custom LUTs and we get this eerie blue-green look!

Light beams from the sun shine down through the trees, washing over the player and creatures. No epic crab fight here. Everything’s fine.

The new skybox creates a pretty amazing sunset. The light beams are shining, the coloring is warm and realistic, and the scattering adds to the effect in the background. Time to relax before night falls.

We’ve also got new environment art, some updated creatures, and a whole new Adventure starting experience in the works, all coming soon in the next update.

For video sneak peek, join us for our next dev livestream on Monday (Oct 30th) at 3:30 PM EST on Twitch and YouTube.

For now, there’s lots of work left to do so we’ll get back to it.

Later gators.

Help Test Controllers + Thanks for Bug Reports!

We need your help to test full controller support on Pre-Release. If you have a controller handy, here are the details:
  • CHKN will now automatically detect when you have a controller connected. Woot!
  • We’ve added cursor emulation so you can control those parts of the UI without needing a mouse.
    • You can disable this emulation in the Options menu if you prefer the OS cursor, but heads up that this completely disables the ability to use parts of the UI with the controller and you’ll need to use a mouse, too.
  • We’ve added default bindings for the following controllers (so far):
    • Xbox 360
    • Xbox One
    • Playstation 3
    • Playstation 4
  • Steam Controller: Default bindings are coming soon. In the meantime, you can set your own bindings (for any controller) in the Options -> Controls menu.
To download the Pre-Release build with controller support, check out these instructions. Tell us about bugs, improvement ideas, or feedback on the forums and we’ll take a look ASAP. Thank you!

“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.”

“CHKN's focus on giving value and life to your creations outside of the simple joy of building may be the first big step in the genre since Minecraft.”
Curse Gamepedia

“I actually really like the idea. [...] A world populated by tame-able creatures.”

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, with genuine personalities and feelings that respond to your actions and the world around them.

Give your creatures unique traits and abilities…

Life blocks 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.

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. The better resources you find, the better the things you can craft!

Fight for survival as you explore a mysterious island…

Work together with your creature companions to survive the many dangers of CHKN, avoid starvation, and defend your thriving homestead.

Get Creative…

If the risk and survival of Adventure Mode aren’t your thing, you can spend your time in Creative Mode with an unlimited supply of every life block and resource at your fingertips. Create whatever you like with no restrictions.

Bring Your Friends…

Want to brave the wilds of Foot Island as a group? Or collaborate on a massive creature and see what happens? Invite other players to join you in any mode and see what you can accomplish together.

Share Your Ideas with Us…

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 and share your ideas. 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!).

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