WELCOME TO AHRA PRIME
Shattered Stars rain down across the horizon. A broken fleet lay in shambles across the scorched skies. The surface storms rage as cowering beasts flee into the caverns below. Your supplies are exhausted, your body bruised and broken. The path ahead is one of pain and hardships. Charon beckons you forward. Will you find your way home?
HIRAETH is an immersive single-player survival experience that challenges players to survive and explore the desolate remains of a forgotten planet. Only the strong can survive merciless AHRA PRIME.
You find yourself alone and out of resources on an forgotten planet that seems to be trying very hard to kill you. Scavenge for food and supplies as you try to piece together the mysteries of AHRA PRIME. The voice of the enigmatic Charon is your only guiding light through the seemingly endless abyss. Where will that light guide you? And what awaits you at the end of the journey?
HIRAETH features two distinct gamemode experiences that share survival mechanics.
- HIRAETH – ETERNAL offers a non-narrative, endless survival sandbox.
- HIRAETH – REVELATIONS is our story mode, with each chapter unveiling a greater mystery. Both will test your survival skills, however, REVELATIONS also features moral decisions with outcomes that significantly affect the world.
☵ ETERNAL
Offers an endless, pickup and play sandbox, ending only with the player’s death. Eternal mode will challenge you to survive utilizing your skill and cunning. As you complete challenges, you will be rewarded with skills that assist on future playthroughs. In-game notes can be found, offering lore and additional tips. Tasks can also be completed, such as repairing installations and accessing databases, that aid in your survival.While exploring the endless horizon, you will discover environmental storytelling, hidden secrets, and unimaginable dangers.
☵ REVELATIONS
A fully crafted narrative experience that unfolds over chapters. Awakening on AHRA PRIME, a delirious survivor attempts to uncover the truth. Guided by a mysterious figure, Charon, the survivor must explore the remnants of the colony, delve into labyrinthine caverns, and survive the planet’s harsh conditions. How far will they go in the pursuit of truth?CHAPTER ONE: DENIAL
“On AHRA PRIME, wise men speakand fools decide.”
DENIAL is the first of many chapters in the Revelations. An amnesiac awakens to find the horrors of AHRA PRIME. With the colony in ruin and the settlers seemingly gone, the survivor must brave the harsh planet’s surface in their pursuit of survival. Charon, an enigmatic figure, will guide them.
UNRAVEL THE TRUTH…
If you can survive
EXPLORATION
AHRA PRIME features a diverse landscape, including mountains, coastlines, and canyons. In order to survive, you must traverse the hellish landscape, collecting resources and scavenging for supplies. Deserted Outposts and dilapidated bases act as markers, helping you navigate the seamless open world. As you complete survival challenges, you can earn perks that will assist in future runs.
PERMADEATH
When you die in HIRAETH – ETERNAL, survival free mode, your save and progress is reset. The wrong choice might cost you everything. The mode will also feature difficulty settings, so that each player can tailor the challenges to their liking.
SURVIVAL
HIRAETH features custom, in-depth survival systems. As you explore and fight, you must manage your oxygen levels, thirst, hunger, and negative ailments. Without vital supplies, nourishment, and rest, you will not survive the planet’s harsh conditions.
RICH STORY
Play through a rich storyline as you explore the world while trying to learn the fate of those who came before you. The full story will be released in chapters with the first chapter available upon release.
LIMINAL SPACES
You must traverse the world of AHRA PRIME for life-saving food and gear items, while avoiding the dangerous predators and environmental hazards. Outposts can act like temporary shelters, but when your supplies are exhausted, you must travel onward. Cowards will starve and the brave will become prey. Which are you?
CRAFTING
HIRAETH features a deep, robust crafting system that must be mastered in order to survive. As you find schematics and recipes scattered across the world, you’ll be able to craft items, food, supplies, and weapons.
Tools, workshops, and recycling stations will assist you, as will portable tool sets. Some tasks can be performed by hand, while more complex recipes require specialized machinery, such as a 3D printer.
FULL BODY AWARENESS
For better immersion, we have introduced a full body awareness system. When looking in first person, you will see your character's movements, clothing, equipment, and held items. This will also allow you to determine an item's condition, for items and weapons deteriorate with use.
EVA SUITS
The EVA suit is your lifeline and only means of surviving the deadly environment of AHRA PRIME. As you explore you will come across different suit types such as pilot suits designed for faster traversal or heavy suits built for greater protection. You can also customize your chosen suit with upgrade modules that add additional functionality and further enhance the suit’s unique characteristics.
UPGRADING
Upgrading your tools and equipment will allow you to survive longer and explore further. Shelters can also be repaired and upgraded. Doing so can increase the efficiency of its workstations or unlock entirely new systems.
PROGRESSIVE SKILLS
HIRAETH is not a typical RPG, but everyone learns something all the time. As you gain experience, you acquire different skills. Some will help you survive, others will speed up your work, and others will enable you to perform more complex activities.After achieving some of them, you will receive them permanently, which will make it easier for you to try again - because you definitely won't end up with just one!
UNLOCKABLES
In each playthrough, after achieving certain goals, you can earn permanent Perks that will make tasks easier in the next playthrough. From the acquired ones, you will be able to choose which ones you want to use and later increase the number you can bring with you.The simplest example would be to increase your stamina after walking a certain distance
FREE UPDATES
HIRAETH will receive free updates over time, including additional story chapters, an expanded world for the survival sandbox mode, and numerous improvements. These updates are free and accessible with the base game purchase.We will not introduce:
- paid add-ons (apart from the already available soundtrack)
- paid content, items, world expansions, storyline - we want to deliver a complete product.
- However, we do not rule out adding paid cosmetic items. These items will not affect gameplay and are pending community outreach.
WORKSHOP
First, we will provide translations by the game community into languages not available in the basic version. Next, we will expand the possibilities of working on HIRAETH

🕹️ Partial Controller Support
🎮 Full Controller Support
The new year dawns over Ahra Prime as well, wanderer carrying strength reborn, skies washed clean, and horizons waiting to be claimed...
A transmission from the HIRAETH development front this time important for the entire gaming universe!
Double FPS at No Extra Charge
The latest HIRAETH update delivers a massive performance leap across all systems with no visual compromises. Players on midrange hardware are now reporting up to 2 higher FPS, and even older GPUs are running smoother than ever.\n\nAs you can see, the oncemythical stable 60 FPS is now achievable even on an RTX 2060 with DLSS set to EPIC or the AMD equivalent.
[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/44720610/68cbea74896124a4b6ebbcab6a7fc907c00603fc.png\"][/img]
Why not on my top rig on Windows 11?
Many Windows 11 users may be surprised to see much lower performance on their systems. I explain the issue along with the full solution in the next section, and the good news is that everything can be fixed. The problem is not related to HIRAETH or Unreal Engine, and as youll see, it affects many other games as well, from small indie titles to major AAA releases.
I encourage you to take a look. Windows 10 players can safely skip this part, but for Windows 11 users its essential and it will also help improve performance in other games you play.
Road to Double fps for free
You can find a short summary in the update announcement below, but heres the full story behind the performance breakthrough.\n[dynamiclink href=\"https://store.steampowered.com/news/app/2646160/view/523111043238463872\"][/dynamiclink]This upgrade comes from deep enginelevel optimizations. \nNo tricks. No hidden settings. Just pure efficiency. \nIf your framerate suddenly jumped yes, thats intentional.
Along the way, I performed detailed bottleneck testing across every major system in HIRAETH. Heres what I found:
My Game Code All Green
No bottlenecks here. Everything runs smoothly, even with a large number of systems constantly monitoring player state, items, world time, and environmental conditions.
Character Animation Heavier Than the Entire Game Code
Character animation costs more than all gameplay logic combined but thats completely normal. Its well within expected limits and does not cause any performance issues.
Rendering Excellent, With Plenty of Headroom
Rendering performance is fantastic. Even on my vintage RTX 2060, HIGH and EPIC settings run smoothly, and stronger GPUs have a lot of room for future visual upgrades. Ahra Prime will continue to grow more beautiful.
World Loading (World Partition) Fully Stable
HIRAETH uses Unreal Engines World Partition system something many developers fear. Here, it works exactly as planned: stable, predictable, and efficient.
AI & Actor Ticks No Issues
General AI logic and actor ticks are clean and lightweight. No unexpected spikes or hidden CPU drains.
Navigation Still a Known Unreal Engine Challenge
Navigation remains the one problematic area. Even after many fixes introduced in Unreal Engine 5.6.1 for openworld projects, several issues remain unresolved on the engine side.
The good news:
the old crashes are gone,
[/*]but heavy CPU spikes can still occur, which can severely impact FPS.
[/*]
For now, Ive temporarily disabled AI navigation while I work on a custom workaround. [u]AI will return in the coming days without the performance penalties.[/u]
Physics Engine Bugs, Now Under Control
Physics bugs in the engine were causing unnecessary CPU load. I identified and removed several problematic objects and edge cases, and since the last update everything has been stable.
Other News from Ahra Prime
Toward the end of the year or the very beginning of 2026 I planned a major update for Nesoi Island. And while not everything made it in, a good part of it did!
I feel especially committed to this project. I know HIRAETH isnt a game for everyone but those who connect with it, really connect. One recent player already passed over 40 hours of playtime just a few days after purchasing the game. That kind of dedication means the world to me.
And I wont rest until Ahra Prime offers enough depth, mystery, and discovery to keep explorers engaged for hundreds of hours. This world deserves it and so do the players who believe in it.
A brandnew location has arrived: Athens, currently in WIP form but already shaping up to be one of the most atmospheric areas on Ahra Prime. Melee combat with the Crowbar is now fully functional, and the UI received a wave of improvements, refinements, and qualityoflife upgrades.
Some of the planned features had to be postponed due to the deep performance investigation and the Windows 11 research described earlier. These issues are critically important not only for HIRAETH, but for many other games as well and solving them now ensures a stable foundation for everything that comes next.
The good news: more quests, more crafting, and more gameplay systems are already on the way. Ahra Prime is growing, and the next updates will bring even more life to the world.
Last Chance for the Steam Winter Sale!
The Winter Sale ends on January 5th and many explorers have already joined the expedition. If you havent yet, this is the perfect moment. As you can see, development is active, steady, and the results are visible with every update.
\n[dynamiclink href=\"https://store.steampowered.com/app/2646160/Hiraeth/\"][/dynamiclink]How far HIRAETH evolves depends entirely on you, the players. Your support shapes the future of Ahra Prime and Im grateful for every single one of you.\n\nss2heart A heartfelt thankyou to everyone who picked up HIRAETH during the Winter Sale and to all new explorers setting foot on Ahra Prime for the very first time. Your trust, curiosity, and willingness to join this journey mean more than I can express. Every purchase, every hour played, every message and screenshot helps this world grow stronger. Welcome to the expedition Im honored to have you here.
Windows 11 Performance Issues Identified & Solved
Some players even confirmed the exact same Windows 11 performance behavior in other titles across different engines including survival games such as Occupy Mars: The Game (Unity), Astrometica (Unreal Engine 5.3), and The Planet Crafter (Unity). This further proves that the issue originates from Windows 11 itself, not from any specific game or engine.
I prepared a clear, stepbystep guide to help players fix:
low FPS on strong hardware
[/*]unstable GPU usage
[/*]sudden performance drops
[/*]Windows 11 background services interfering with games
[/*]
If youre on Windows 11 and performance feels off, the guide will help you restore full power.
Windows 11 Input Issues Player Help Guide
A small number of Windows 11 users reported:
incorrect draganddrop values
[/*]UI elements clicking in the wrong place
[/*]problems connecting oxygen or interacting with objects
[/*]cursor offset or inconsistent input
[/*]
These issues are caused by Windows 11 DPI scaling and input handling and they affect many modern games, not just HIRAETH.
I created a dedicated Input & DPI Fix Guide for All Games, including:
DPI override fix
[/*]multimonitor scaling fix
[/*]pointer precision fix
[/*]fullscreen optimization fix
[/*]Raw Input workaround
[/*]HDR/VRR/GSync compatibility notes
[/*]
If your interactions feel off, this guide will help you fix them in minutes.
I have no control over Windows 11s performance behavior that part is entirely on Microsofts side. However, I will be updating HIRAETHs own scaling and input handling soon. Its a significant amount of work, so it wont happen tomorrow, which is why I strongly recommend applying the fixes on your side right away.
[u]The bonus is that these changes will also improve performance and input accuracy in many other games. Some titles may never receive proper Windows 11 updates, so taking action now will benefit your entire library.[/u]
Thank you, Explorers
Your reports, screenshots, and patience helped us track down issues that even Microsoft hasnt fully documented yet. Every fix we ship makes HIRAETH stronger and your feedback is a huge part of that process.
Stay curious. Stay brave. And remember: the stars are watching.
As we step into the new year, I wish you clear skies, smooth framerates, and countless unforgettable journeys both on Ahra Prime and beyond. May 2026 bring you discoveries worth sharing, victories worth celebrating, worlds worth exploring and simply good luck, and happiness, wherever your path leads.
