From Green Hell to StarRupture

Hello everyone,

A short story time from us!

When we established Creepy Jar back in 2016, we wanted to create a company that would make horror games - just take a look at one of the earliest concept arts from us:



Our vision changed rather quickly, and in August 2019, we launched our first game in Early Access: Green Hell - an open-world survival simulator taking place in the uncharted Amazon jungle.

A keen eye will find the horror elements still left in the key visual for Green Hell ;)



Check out this very first announcement trailer for Green Hell - published back in May, 2018:

Since its full release in September 2019, we’ve supported Green Hell with over 21 Content Updates: we’ve added online co-op mode, an additional storyline, added a bunch of new mechanics you’ve requested and new features that we thought would be valuable additions to the ultimate survival experience.



We’ve had so much fun not only while we were creating them, but also when we were looking at your reactions in your reviews, comments, and hours of content you’ve made with the game.

Now, before us stands another great milestone in our studio history - a brand new game, a completely new IP in a sci-fi theme. Although it's not a spiritual successor to Green Hell, it sure contains the Creepy Jar survival essence for those still hungry for extreme experiences.

StarRupture is a first-person open world base-building game with advanced combat and tons of exploration. It’s a fusion of our experience and lessons learned from creating Green Hell, as well as the valuable feedback we gathered throughout the years from you, our Community.

StarRupture will feature both single-player and online co-op from the start in its Early Access debut. So no matter if you prefer the lone wolf experience or help from your buddies (watch out for the friendly fire, though!), you will be set for an unforgettable adventure while trying to survive on this sublime and ever-changing planet, extracting and managing resources, creating your complex industrial system, and fighting off hordes of alien monsters.

We’ll be more than thrilled if you try it out in action when it launches on Steam on January 6th, 2026.



No matter if we’ll see you either in the heart of the Amazonian Rainforest or on Arcadia-7, a mysterious alien planet, we hope that you will have fun while playing our games, and collect memories worth telling to your closest ones.

Yours as always,
Creepy Jar Team

If you prefer the lone wolf experience - no worries, the single-player option is still available.

[previewyoutube][/previewyoutube]
Running from December 3rd to December 8th, this co-op playtest offers the first exciting taste of StarRupture gameplay. If you want to get in, just click the Request Access button on the game’s product page in the Steam Client and download the Playtest.
You may also invite your Steam Friends to join you on the adventure by sending them an invite to the Playtest, so you can build, explore, and survive together on Arcadia-7 planet.






StarRupture Playtest Co-op Round:
What You Need to Know



Welcome to StarRupture, an intense first-person open-world survival game where you’ll build sprawling industrial bases, harvest valuable resources, and battle alien monsters—solo or in a group of up to 4 players. The planet is gorgeous, dangerous, and constantly evolving. Exploration, combat, and creativity are your keys to survival.





[h2]🧪 How to join the playtest?[/h2]


The closed playtest runs from today till December 8th. To join, just head over to our Steam page and click “Request Access.” It’s that easy—and yes, it’s 100% free!





[h2]🎮 What’s in the Playtest?[/h2]

The StarRupture Co-op Playtest features an early slice of the game, featuring the game's core mechanics, a guided tutorial (in single-player mode), and a free play option with map restrictions.


Some gameplay mechanics and more advanced progression levels will be locked out for now (and left for you to fully explore when the game launches in Early Access on January 6th, 2026), so don’t worry about the spoilers; the game will have plenty of fresh and new elements once it launches!


The Co-op Playtest features a more polished experience than July’s Single-Player Round Playtest: we’ve tweaked the performance, ironed out a lot of gameplay mechanics, and we’ve squished a lot of bugs (tons of Vermin were harmed during our internal playtesting), and yes: the autosave is working now!


Your feedback on the playtest will be really helpful for us to deliver you the best possible experience on the Early Access launch - you can fill out our short feedback form over here.

There is no time limit on your session—play as much (or as little) as you want! However, this event will be limited only by the good old calendar - it will finish on December 8th.





[h2]🤝Meet our (anti)heroes[/h2]

During the Co-op Playtest, you will be able to try out in action all of our 4 (anti)heroes - each with their own backstory, traits, and character. They will have plenty of chances to speak with GAL and each other to comment on the current situation. Be sure to try out each one of them to see who is your favorite, before the game launches in Early Access ;)
