About this game
You were born on a dangerous planet. Surreal and fantastical environments, teeming with exotic creatures that defy description. This world is both terrifying and awe-inspiring, as full of wonder and mystery as it is dangerous. But whatever dangers can be found pale in comparison to this world’s biggest threat: The Cylinder. This gargantuan, ancient rolling structure crushes everything in its path. But where did it come from? And how can it be stopped?
In this place, you are but a tiny creature called a Trebhum. While you may not be the fastest or the strongest, you have the most powerful ability of all: adaptation. Trebhum can mutate and evolve new physical attributes and abilities that can help them defend themselves against predators and navigate through this perilous world; what you lack in size, you’ll need to make up for in improvisation and resourcefulness. So, prepare yourself, little Trebhum. Gather your family for the dangerous journey ahead and save your world from The Eternal Cylinder.
An unforgettable alien world to explore…
A vast, open world that contains four unique biomes, each filled with extraordinary flora and strange fauna. What wonders, or horrors, lie ahead will surely be unforgettable.
…with real-time world destruction.
Every time The Cylinder roars to life, more of your beautiful planet is crushed under the weight of the ancient destroyer. Trees fall creating obstacles to escape while hills and mountains are flattened leaving nowhere to hide. Your only chance of survival is to run!
Build Your Own Alien Family
Each Trebhum can choose from 50+ mutations that give them the ability to grow spikes, shoot tornadoes, fly, and more! This allows Trebhum various methods to overcome any obstacle they face! Additionally, each mutation gives Trebhum unique appearances, meaning Trebhum herds become a diverse cast of lovable creatures customized for ultimate survivability.
Solve Ancient Mysteries
In hidden sanctuaries, built by generations past and protected by complex puzzles, is the ancient knowledge passed down from generation to generation of Trebhum. Seek these sanctuaries out for they house the only hope your world has left.
Watch out for The Cylinder’s servants
Servants are abominations created by The Cylinder; infesting, destroying, and consuming every natural thing on the planet, leaving nothing behind. Stay as far away from these monsters as you can!
*ANNIVERSARY UPDATE - NEW CONTENT*
New Creatures to Discover!

The Eternal Cylinder - Patch #3 is live!
Hi everyone! Patch #3 is now live, check out the details below. {STEAM_CLAN_IMAGE}/42566303/3a338313279b8c6246aab002c8cb1428f10dac17.png Patch notes and fixes for Hot Fix 3 (aka Patch 3): A progression bug that could manifest in several different ways is now fixed. The bug could cause non-progression at the end of chapter 2, and several barriers should have been red to present as blue instead, letting you pass through. In addition to the original bug being fixed, existing save games that have been affected by the bug are also repaired, but for the repair process to occur correctly, you need to load your game, save manually, and then load again from that save. You only need to do this is you were unable to progress. The green fog around certain plants in the tundra was made too bright by a change from Patch 2, this has now been corrected. The volume of the sound effects for the Buddugh Gropp has been adjusted. The game's custom Near Depth Of Field effect can now be turned off from the game's ini files. You can set r.DepthOfFieldQuality=0 in the section of Engine.ini If you'd like to support the game and team, please consider leaving a positive review on Steam.

The Eternal Cylinder - Patch #2 is live!
{STEAM_CLAN_IMAGE}/42566303/a5d29eedbcf6c2cc139426b1f7cc6b8b0297801a.png Hi everyone! We continue to listen to your feedback and make improvements to the game. Huge thanks to you, our Community, who continue to share your experiences, talk about your fun adventures, and let us know your thoughts. Patch notes and fixes for Hot Fix 2 (aka Patch 2): The high-quality skylight has been reimplemented to have minimal overhead. The option to toggle it has been removed as there were no noticeable differences in performance during testing. The game now falls back automatically to DirectX11 when DirectX12 is not available (note: this does not fix the startup crash on systems incompatible with FSR2.0) If you'd like to support the game and team, please consider leaving a positive review on Steam. It means the world to us and helps others get an understanding of what The Eternal Cylinder world is like. https://store.steampowered.com/app/865680/The_Eternal_Cylinder/ Join us on Discord here to chat more!Read full article on Community Announcements (Good Shepherd Entertainment)Patch NotesOfficial

{STEAM_CLAN_IMAGE}/42566303/45425e26a941b76377b54eb8aa5f692041799b33.png Hi everyone! Thanks for your warm welcome on Steam and for all your feedback! We are rolling out our Patch 1, here are its contents: Patch notes and fixes for Hot Fix 1 (aka Patch 1): Optimized Raytracing profiles configuration Fixed crash when playing with PS4 and PS5 Controllers Fixed Hand of Fate and Liberator destructibles popping out of scene. Fixed potential loading of incorrect Elder Cave during progression. Fixed mouse controls in Mutation Tree Increased new creature spawn rate in Chapter 3. Fixed some randomly spawning destructibles at coordinates 0,0,0 Gas bombs no longer kill the player so easily. Demo progress now auto-rolls over. Please note: if you played the demo and beat the demo, and then didn't have your progress roll over/started a new file, your game will revert to your demo progress. To maintain your current progress, you will need to delete the SavedData_Steam.sav file from your local files and leave only the SavedData.sav. Please Note: We are still investigating the stuttering issue with the High-Quality Sky Light. Global illumination changed between Unreal 4.24 (old engine) and 4.27 (current). For the time being it is disabled by default. We hope you'll enjoy the improved experience! If you want to reach out to us or discover more about the game, join us on Discord here!
