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!).”

Boss Design Challenge Winners!

Huge thanks to everyone who entered our inaugural Creature Design Challenge: Bosses! We had a tough time choosing but ‘tis the life of a CHKN scientist. If you didn’t win this time, don’t worry. We want to fill CHKN with all your awesome creations so we’ll have another design challenge for you soon.

These are our choices. We also want to hear your votes in the comments below so we can put your favorites in a future release! Let us know which creatures you’d love to fight against (or even just run across) in CHKN.

Runihara Thanatos by Ultimate Oddball!

Runihara is definitely a creature we don’t want to run into while exploring, which is why it makes an excellent boss creation. Looks and functions great in-game? Check. Quick and scrappy? Check. High health and DPS? Check. Multiple abilities? Check. Tough and fun to face off against in a fight? Double Check!

Congrats, Ultimate Oddball! We’ll be adding Runihara Thanatos to the game in a future release.

Runners Up
These creatures were also really fun to fight and look great in-game. Plus they kind of give us nightmares. Congrats to ramenhar and Jelly Butter!

Cow spider by ramenhar will come at you quickly and then there’s fire everywhere. Fun to fight against, and frightening but also kinda cute somehow!

Arms by Jelly Butter has an amazing strike attack that’s very effective. It may seem like a hug at first but don’t be fooled. Pro Tip: dodge and weave!

Honorable Mentions
These are some great submissions that we loved for their own awesome reasons.

Weirdest entry goes to Hugh-Man by Rowdyruff Muffin. We mean that in a good way, as you can see in this screenshot from its Workshop page. (Rowdyruff’s other entry, Bubblebert, is also weird-in-a-good-way. Check that one out, too.)

Crawly abomination by squidking was definitely the creepiest. Load this up in your game and then run away screaming. Or tame it if you’re not afraid of spiders... but who’s not afraid of spiders!? (Squidking also has three other great entries so be sure to take a look at those!)

Scorpion Mech by BarinAsh isn’t very effective in a fight but it just looks super dang cool. Very creative use of these blocks. (BarinAsh has a whole collection of amazing mech replicants if you like robot creatures.)

We underestimated Fuzzy Hairder by Lordofd. We thought fighting this thing would be easy. We were wrong. And it has a great ‘do.

Cerberus by Crystalseeker is actually really deadly but... dawwww look. It’s so cute! Tame this and you’ve got an excellent battle companion.

Put a saddle on The Block by Tycothepug and you have a really great battle mount. Try it out! The attacks are very effective. (And try out Tyco’s other creative entries while you’re at it.)

We did not expect a Nail Clipper by STEVEBILLYBOB. It somehow matches its name perfectly, plus it’s fun watching it try to attack with both mouths. (We’ll work on that back neck functionality!)

And finally, in the “Pfft, Rules Schmules!” category, SpyCakes, ardutton, and JuliaAiko went over the orb limit but we had to show off their creatures anyway.

The Land Kraken by SpyCakes was just over the orb limit but it’s a beast with both poison and ink shooting. Watching it glide around with its carefully placed octolegs is mesmerizing.

Potoooooooo by ardutton is a merciless charger, who also looks great with all those feathers. Probably keeps it nice and warm in the winter, too.

And this is Boss Creature by JuliaAiko, the fluffiest T-Rex. Not sure whether to run away or hug it. Many points for creativity.

(Looks like we need to work on screenshots for larger creatures too, whoops.)

Winner Announcement Live Stream
We showed off the winner and runners up in our live stream earlier today and explained more about our choices. Check out the video on YouTube to see them in action!
If you want to try out these creations in your own worlds, make sure to subscribe to them in the Workshop. You can use the links above or here’s a handy collection of ALL the submissions for you to play with:

Nov '17 Boss Challenge Submissions Collection

There were some other really great entries that went over the 2400 orb limit rule or weren’t boss fight material even though they looked really cool, etc. We included those in the list anyway. We’re definitely saving some of these to add to the world in the future!

Don’t forget that you can always share your amazing creations to the Workshop by using the menu in game. Just hold [E] and select “Save to Workshop".

It was a lot of fun looking through all your great entries. We hope you had fun creating them! We can’t wait to see what you build for the next challenge.

Design a Boss for CHKN!

Enter our boss design challenge! Your boss creature could be featured in a future game release, standing guard over some epic loot and striking fear into the hearts of players everywhere. Here’s how to enter. Good luck!

The Rules
  1. Build a boss creature within a maximum orb limit of 2400 and save it to the Workshop
  2. That’s it! Your boss creature can use any Life Blocks in any combination you like. It can be scary or cute or a true abomination. It’s up to you.

Whoops! Over 2400 orb limit! Gotta remove some parts...

How to Enter Your Creation
  1. Launch CHKN in Creative Mode
  2. Build your boss under 2400. Have fun and get creative!

  3. Exit the build sphere and save your creation to the Workshop so we can see it. (Use the [Q] command on your creature and select “Save to Workshop”.)

  4. Make sure to give your creature a name! Add “Boss Challenge” to the title or description to help us find it more easily.

You’re done! If you have more than one idea, fear not. You can enter as many times as you like.

All creatures saved to the Workshop before Tuesday, Nov 28 @ 23:59:59 EST will be entered into the challenge!

Who Will Win?
Once entries are closed, our crack team of CHKN scientists will go over all the entries and try our best to narrow them down to a winner. We have a feeling this will be really tough but also very fun!

We’ll announce the winners and show off our favorite entries during our next live stream on Friday, Dec 1 @ 3:30 PM EST. Join us!

“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!
