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 Life Blocks 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. Our next big update is coming Winter 2018.”

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, Adventure, and Arena modes for playing and testing, so you can build creatures using 150+ Life Blocks and dozens of 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 pit creatures against each other in battle. 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, so you can let us know what you think of what's coming and what you'd like to see added.

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

First Look at the New CHKN! (v0.7)

Version 0.7 is now on the Live branch for everyone to play! Check out the highlights below or download the update to try them out yourself. And if you’re a CHKN veteran, make sure to read *Important Notes for Returning Players* down below!
This update gets us another step closer to v1.0 of CHKN and we need your feedback! We know there are still some things to iron out in this build and we’d love to know what you’d like to see in the future. All your feedback really helps us prioritize development and improve the game. Please help us test and post your feedback on the discussion forums or in our Discord.

Creature Building
You asked for better building so we’ve revamped the Creature Builder! The improvements make it easier to use and design the creature you want to build. We hope you agree. Try it out and let us know. You can drag & drop or click to place blocks, sort blocks by animal type, move whole chains of blocks, undo/redo block placement, and see all the stat and ability information at a glance.

Every block matters! All Life Blocks add to your creatures’ stats. What’s important is how you combine and place Life Blocks when designing creatures in order to grant abilities and traits to your companions.

Abilities are special skills you can assign to creatures (like a stun ability to slow down quick opponents or a healing ability for team fights). To unlock an ability, you’ll first need to defeat or tame a wild creature and collect its “ability recipe” (a scroll will drop). The recipe is then added to your Journal so you can see what combinations of Life Blocks are needed to grant that ability to your creature. There are a limited number of ability slots available for each creature, though, so you’ll have to choose wisely! Here are just a few of the 28 abilities currently in the game:
  • Crab legs + Crab shell blocks = Hunker Down (armored force field)
  • Mech Dino eye = Laser Eye
  • Chicken Face (block, eye, mouth, comb) = Squawk Stun
  • Cat legs + Cat tail = Teleporting Vanish
  • 50% Cat blocks = Nine Lives (automatic revive)
  • 4 wings = Wing Gust (knockback)
Traits, on the other hand, are attributes and personality inherent to creatures. Some are passive like vision, diet type, and aggressiveness, but there are also more advanced traits with helpful benefits. A creature with the right traits could provide dung fertilizer for farming. Or add the Glide trait so your creature can cross larger gaps in the world.

Wings are pretty darn useful.

Ten animal types have a whole new look: Chicken, Cat, Crab, Dog, Snake, Pig, Spider, Elephant, Cow, and the poachers’ Mech Dino. Each animal type now has more Life Block size variety too, with an average of 10-12 Life Blocks per animal, so there are more ways to design and be creative. (We started with your most-used animal types and the others will be getting their upgrades soon. Tell us which ones you want to see next in our creature thread on the forums!)

The arena is a brand new mode where you can experiment and test your creature designs in battle. Try 1v1 in an Exhibition Match, pit groups against each other in Team Elimination, or fight your way to victory through increasingly difficult challengers in the Tournament mode.

The arena crowd will cheer you on… or boo you if they feel like it. They’re very fickle.

Adventure Mode
Discover the new improved world of CHKN where you must survive on an island populated by mysterious creatures. With this update, we’ve added progression for players. Power up your Lifeshaper and experiment with blocks to make better creatures and take on tougher challenges.

Oh, sorry. Is this your temple? I’ll just... *flees*

A new intro experience with a few starter quests teaches the ins and outs of surviving the wilds. Progression has been updated, new wild creatures spawn throughout the world, improved the UI (including new discovery notifications), and lots more to make survival more challenging and rewarding. Jump in and see if you can become a master survivalist!

Crafting at a creature-powered workbench.

Crafting is now easier and clearer. The new interface and organization is a major improvement. We’ve also added new recipes and items that help you harness the power of the creatures you discover. You’re gonna want to start collecting creature parts for some of these tools...

Not sure this chicken should be excited about something called the Chicken Claw Rake.

You’ll need the new updated Journal to survive and master the wilds of CHKN. Use the journal to make your own goals, whether it's to build a homestead, fight the poachers, hunt for the elusive RepigDog, or just collect and discover all the creatures. The journal has all the information you’ll need: Life Block stats and abilities, item recipes, where to find items and resources, and a list of creatures to discover.

Get all the info you need on a creature you’ve found in the world, or check out items you’ve discovered using the categories on the left.

Art & Environment
The all new island has 2 km2 of wilderness to explore, complete with new art for the Tropical Biome. Trees, bushes, rocks, resources, and temples have all been revamped and are looking quite spiffy if we do say so ourselves.

Feel more like an adventurer with the updated player avatar. And check out the new look for our favorite arch nemesis, the Poachers.
Did we mention armors yet? Yeah, there are new armors you can craft based on creature parts. Each provides a different armor rating and usefulness, plus they make you look rad.

Cow, Chicken, and Cat armors. (Plus Crab, too!) We want these as action figures on our office shelves.

** Important Notes for Returning Players **
FPS & World-Streaming Stutter:
We’ve optimized almost all the systems and increased FPS on recommended spec machines as well as reduced duration and intensity of world-streaming stutter. If auto-detect doesn’t pop up to determine your optimal settings (it only runs after a fresh install), you can adjust them manually in the Options menu. Check out this post with suggestions for which options to change to help find the best performance for you.

However, note that there are still some hitches in framerate because world-streaming is not yet fully optimized. We will remove all world-streaming stutter for recommended spec computers in our next update.

Workshop Creatures
Your saved Workshop creatures will not be able to be imported. You won’t see those creatures or be able to spawn them in game. We’re starting with a clean slate in the Workshop with this update. But, all old saved creatures are still there in the Workshop if you want to play in the Legacy branch (see below).

Legacy Branch
The old version of the game (v0.4.5) is now on a separate branch for you to play.
  • You can swap to this branch by right-clicking on CHKN in your Steam Library, selecting “Properties”, clicking on the “Betas” tab, and then selecting “Legacy” in the dropdown menu.
    • Swap back to “none” at any time to return to the latest live build.
  • You’ll be able to see all the old Workshop creatures in this build.
  • Your old saves are still there! You can bring them to this Legacy build by copying them over manually.
    • Go to C:\Users\YOURUSERNAME\AppData\LocalLow\Katapult\CHKN
    • Rename your “SavedGames” directory to “SavedGames_legacy”
  • NOTE: Since the legacy build is now an old version of the game, it’s no longer supported.
Known Bugs/Issues
  • If you have a lower-end computer, you might not see any grass. We’ve turned this off for now to improve performance and are looking at replacements.
    • To turn off grass manually, go to Options -> Performance and turn off Grass Rendering.
  • Sometimes a creature will get stuck on something in the world and stop following you. We’re working on Pathfinding updates to fix this but you can use the Party menu to quickly store and spawn it as a quick fix in the meantime.
Patch Notes… Too Many to List!
There have been a lot more changes to the game during Pre-Release development so the patch notes are too long to list here. If you want to check out all the patch notes from the Pre-Release updates, visit the News page and scroll back through the entries.

There’s more to come! Here’s our roadmap for the rest of the year.

Coming soon:
  1. Improved world-streaming / reduced stuttering
  2. Arms! Punches, kicks, cat-scratch for creatures (Legs will be able to act like arms!)
  3. Dog armor
  4. Bug fixing (of course)
  5. You tell us! (Post on the forums or Discord and let us know what you’d like to see.) And check out our Roadmap...

We really want to know what you’d like to see next. We love your feedback and read all your comments and ideas to keep us motivated in the wee hours. (What is sleep?!) We’re working as fast as we can to make CHKN everything we know it can be and we couldn’t do it without you.

Adventure Dev Stream!
We’re really excited about this release and we’ve been having so much fun in our Multiplayer Adventure tests so let’s turn on the stream! Tune in later this afternoon, Nov 30th @ 3:30 PM EST. Come hang out with us on YouTube or Twitch and tell us which creatures to build, help us survive, and ask us any of your burning CHKN questions!

First off, big thanks to all our previous creature contest entrants. The creativity of the MANY amazing Workshop creators really inspired us as we revamped creatures and repopulated the world. And we haven’t forgotten you, winners! Since not all the revamped blocks are in yet, it’ll be a bit before we can add your amazing creatures to the world but don’t worry. We’ll add them in as soon as we can.

And special thanks to all our Pre-Release testers, Workshop creators, and everyone who supports us. Your feedback and comments mean a lot and really help us make CHKN better. Thank you!

If you want to help us test, send us your feedback, or talk to us directly, here are some handy links:
Back to work for us. Bye~~!

Pre-Release Update v0.6.91

First off, happy Thanksgiving to all our friends in the US celebrating tomorrow! We’ve already started getting ready for our CHKN Team feast...

Step 1: Finding the right turkey… or is it TRKY?

Before we’re full of way too much food, we’ve put out an update to Pre-Release with more improvements as we prepare to push to the Live branch. (Note that your previous Pre-Release saves are invalid and won’t load.) Patch notes are below and, as always, bugs are expected in these work-in-progress builds so we really appreciate your help testing and reporting feedback on the Pre-Release forum. * If you’re not familiar with Pre-Release, it’s the unstable developer branch we use for testing new stuff. More info here.

If you’re not a Pre-Release tester, check out this video for a look at some of the features and updates coming to the Live branch!
We’ll also be playing the Arena on our developer live stream today, Nov 21st @ 3:30 EST on Twitch and YouTube. Come hang out! Help us build creatures and see who comes out victorious.
