A first‑person hard sci‑fi survival game on Ahra Prime. Explore, craft, fight, and endure a hostile alien world. Story Mode begins — uncover what happened to the vanished colony.
HIRAETH is a first‑person hard sci‑fi survival game set on the alien world of Ahra Prime. Manage oxygen, suit integrity, temperature, stamina, injuries, craft tools and weapons, explore handcrafted regions, face predators and environmental hazards, and uncover the mystery of a vanished colony.
A gripping hard sci-fi survival experience about isolation, resilience, and the quiet search for belonging in an alien wilderness.
Hiraeth – a word for the ache of longing for a home you’ve never seen —
and for those stranded on Ahra Prime, it becomes something more.
Is home a place you return to… or one you forge in the void?

You awaken alone on Ahra Prime—a vast, unforgiving planet where a thriving colony once stood. Now it's silent. Empty bases hum with failing power. Systems flicker. But no one remains. Every breath draws from dwindling oxygen. Every step risks suit failure or unseen predators. Every choice echoes across a world that doesn't care if you survive.
Your only goal: endure long enough to unravel the mystery of what happened here—and decide what home means when everything familiar is gone.
HIRAETH is not a simple or forgiving survival game. It’s built for players who enjoy:
Hard sci‑fi survival — deep, demanding systems where oxygen, power, hunger, hydration, temperature, and suit integrity matter every minute. No hand‑holding; every mistake has consequences.
Atmospheric, immersive worlds — a slow‑burn alien environment that rewards patience, observation, and curiosity.
Exploration with real tension — a handcrafted island you can scout from afar, dynamic day/night cycles, and unpredictable encounters.
Developed by a solo true indie creator — with a proven track record of consistent updates, transparent communication, and a world shaped directly by community feedback.
Games that grow on you — tough at first, deeply rewarding once you learn its logic and uncover its mysteries.
HIRAETH blends hard sci‑fi survival with atmospheric exploration. Every system is designed to keep you on edge:
Oxygen, hydration, hunger, temperature, stamina, and suit integrity
Equipment durability and maintenance
Dynamic time and weather affecting fatigue, item wear, and visibility
Predators, environmental hazards, and unpredictable encounters
There’s no hand‑holding, no guided path — even in shelters and bases, danger is never far.
Just you, your EVA suit, and a planet that wants you gone.
Your journey begins on Nesoi Island, a handcrafted region you can scout from afar — even through a sniper scope. Explore land, underwater caverns, abandoned structures, and ruins. Every location hides resources, lore fragments, and clues about the world’s collapse.
As Early Access progresses, Ahra Prime will expand dramatically with new biomes, regions, and vehicles that unlock previously unreachable areas.

An endless survival sandbox where every run is a test of skill and adaptation. Learn the systems, push deeper into the world, and uncover lore that evolves with each attempt.
A narrative journey told across five chapters. Discover the truth behind Ahra Prime, guided by the enigmatic Stranger. Each chapter offers a complete arc with no cliffhangers — culminating in a grand finale.
Story Mode begins unfolding during Early Access, with quests, messages, and early narrative systems already in place.

HIRAETH rewards mastery and experimentation:
Progressive Skills & Perks that shape your playstyle
Challenge Mode arriving during Early Access for structured objectives
Over 20 Steam achievements available from day one, with many more planned
Multiple difficulty levels, from relaxed exploration to brutal survival
Every run feels different thanks to randomization, player choice, and evolving world systems.
Crafting & Upgrades — build tools, weapons, and survival gear
EVA Suit enhancements — improve resistance, efficiency, and survivability
Companions — choose between a quirky alien slug or a high‑tech droid
Vehicles — traverse long distances and reach remote locations
Full Body Awareness — see your entire body and equipment in first‑person (optional for motion‑sensitive players)

A dedicated Training Course introduces the core mechanics, ensuring everyone can learn the systems at their own pace.

Immerse yourself in the desolation of Ahra Prime with an electronic soundtrack crafted to enhance tension, loneliness, and discovery.
HIRAETH is created by a solo developer who works closely with the community. Frequent updates, transparent communication, and player‑driven improvements are at the heart of the project.
If you enjoy titles like The Long Dark, The Solus Project, Subnautica, or Returnal, you’ll feel right at home — or as close to home as Ahra Prime will ever let you get.
HIRAETH is designed as a deeply personal journey:
Full control over pacing and exploration
No waiting for others, no toxicity, no interruptions
A world that grows with you, not against you
A game you can return to years later — no servers required
Most survival games follow a familiar loop. HIRAETH breaks the mold with:
Innovative survival systems
Meaningful progression
Atmospheric worldbuilding
Player freedom and replayability
Accessibility without sacrificing depth
Elegance over grind
Your story on Ahra Prime is yours alone.
Every choice matters. Every mistake teaches. Every discovery pulls you deeper.
