Permafrost has two meanings in this title. In geoscience, it is ground that remains at or below 0°C for at least two consecutive years. In video games, Permafrost is a story-driven survival sandbox set in a fictional frozen, post-apocalyptic world. The game borrows the danger of persistent cold, but it is not a simulation of real permafrost science.
This guide explains the Earth-science term first, then separates it from the systems advertised for the PC game: temperature threats, preparation, exploration, crafting, shelter building, machines, progression, the dog companion, and co-op.

What permafrost means in Earth science
Permafrost is ground—soil or rock, including any ice and organic material within it—that stays at or below 0°C for at least two consecutive years. The definition is based on measured ground temperature and duration. It does not require a particular amount of ice, so permafrost can contain little ice or be effectively ice-free.

“Permanently frozen” is therefore misleading. Permafrost can thaw when heat reaches the ground; the formal term records a temperature condition sustained over time, not a guarantee that the ground can never warm.

The active layer above it
The active layer is the near-surface soil above permafrost. It thaws during the warmer season and freezes again seasonally. Its thickness and behavior are not uniform: snow cover, vegetation, moisture, soil type, shading, disturbance and local climate all affect how deeply seasonal heat penetrates.
Because frozen ground can restrict drainage, water may remain near the surface. Wetlands, ponds, lakes and marshes can occur in permafrost terrain, although local topography and hydrology determine whether they develop.
Depth and continuity vary widely
Permafrost is not one continuous sheet beneath every cold landscape. The National Snow and Ice Data Center reports thicknesses from less than 1 meter to greater than 1,500 meters (the source page does not state a year for that range). Mapping commonly distinguishes continuous, discontinuous, sporadic and isolated permafrost. Two nearby sites can therefore have very different ground conditions.

What happens when permafrost thaws?
Thaw is the progressive loss of ground ice as heat enters the soil or rock. The consequences depend on ice content, slope, water, vegetation, snow, geology and human disturbance. A low-ice site may show little visible change, while excess ice can produce major settlement.
Settlement and thermokarst
When excess ground ice melts, the ground surface can settle or collapse into irregular thermokarst terrain. Depressions may collect water, changing drainage and creating new ponds or lakes. The surface does not necessarily sink evenly, so roads, buildings and utilities can experience differential movement.
Slopes, polygons and vegetation
- Thaw slumps: unstable, ice-rich slopes can fail as thaw removes the support provided by frozen ground.
- Active-layer detachments: a saturated, seasonally thawed layer can slide away from the still-frozen material beneath.
- Degraded ice-wedge polygons: patterned ground can lose its sharp polygonal form as ice wedges melt.
- Thermokarst lakes: thaw-related depressions can fill with water, though drainage changes may also empty existing water bodies.
- “Drunken forest” trees: tilting trees can indicate uneven ground movement, but their presence is not proof of one identical thaw process everywhere.
The National Park Service identifies practical hazards including slope instability, thaw settlement, drainage changes and infrastructure damage. Climate, terrain, hydrology, vegetation, geology and disturbance all influence the outcome, so no single visible sign appears at every thawing site.

How to compare two real permafrost sites
Useful comparison questions are:
- What are the ground temperatures and the depth of the frozen layer?
- How much excess ice is present?
- Is the permafrost continuous, discontinuous, sporadic or isolated?
- How deep is the active layer, and how does it change seasonally?
- What are the surface drainage, moisture and slope conditions?
- How do vegetation and snow cover insulate or expose the ground?
- Has construction, clearing or another disturbance altered heat and water movement?
What is the game Permafrost?
The PC game Permafrost is advertised on Steam as a story-driven survival sandbox in a frozen, post-apocalyptic setting. SpaceRocket Games is listed as the developer and Toplitz Productions as the publisher. The listed Early Access release date is October 9, 2026. Its setting is fictional; the title should not be read as a promise that the game models real ground-temperature data or thaw mechanics.
What’s actually slowing this PC down?

The store-page copy captures its design premise with the line, “The cold is alive and ever-present.” That is marketing language for the game’s constant survival pressure, not a scientific description of permafrost.
How the advertised survival loop works
The listing presents survival as a cycle of preparing for cold, venturing out for resources and technology, then returning to improve the equipment and shelters that make longer trips possible.

Cold, frostbite and storms
Frostbite, storms and creeping cold are named threats. Staying outside is therefore a risk-management problem: a trip must justify the supplies and technology it may yield, while leaving enough margin to return before conditions become dangerous. The page does not provide independently tested temperature thresholds, damage rates or a complete status-effect formula, so those details should not be treated as established mechanics.
Explore frozen cities and wilderness
Players are expected to move between abandoned urban areas and wilderness. Exploration supplies the raw materials and discoveries needed for survival, but exposure and hostile danger make route planning important. The listing describes a world in which progress is gated by what the player can recover and repair rather than by simply walking to every location at the start.

Hunt, scavenge and craft
Hunting and scavenging provide the resources for crafting. Crafting is presented as part of preparation for harsher excursions, rather than as an isolated menu activity. The store page does not publish a full recipe list, resource table or production-time data, so exact item requirements will depend on the live build.

Repair machines and restore shelters
Recovering technology and repairing machines are central to pushing farther into the world. Abandoned shelters can be restored, and the advertised shelter network gives the player more than one place from which to stage expeditions. The practical implication is a forward-planning loop: establish or improve safe points, then use them to reach areas that were previously too costly or dangerous.
A dog companion
A dog is advertised as a companion that can scout, warn of danger and carry supplies. Those roles make it useful for reconnaissance and carrying capacity, but the listing does not specify its detection range, inventory size, combat behavior or survival requirements.

The store listing describes both single-player and online co-op. One player can go alone, or a party can include up to three friends, for a listed maximum of four players. Co-op changes the planning problem: players can divide scouting, hunting, hauling and repairs, but the available information does not establish whether every objective scales with party size or how revives and shared inventories work.
Steam features and PC requirements
Steam lists achievements, trading cards, Steam Cloud, stats and Family Sharing for the game. Store specifications and availability can change during Early Access, so check the live listing before purchasing or installing.

The live listing does not establish the processor, graphics-card or DirectX values, and no independent performance test is available. Treat the RAM, storage and operating-system figures above as the listed requirements, not as a guarantee of a particular frame rate or visual preset.
A practical first-session plan
- Read the cold situation before leaving shelter. Identify the immediate threat—ordinary exposure, a storm or a frostbite risk—and avoid committing to a route with no return margin.
- Choose a short objective. Start with nearby scavenging, hunting or a repair task rather than a deep wilderness run. The advertised progression rewards technology recovery, but the first priority is getting back alive.
- Carry for the job. Leave room for scavenged materials and supplies. The dog’s advertised carrying role can help, but its exact capacity is not stated.
- Use restored shelters as staging points. Repairing and linking shelters should reduce the distance of later expeditions and give you more options when weather turns.
- Invest discoveries in access. Recovered technology and repaired machines are described as the means of reaching farther areas, so prioritize upgrades that remove the next exploration barrier.
- In co-op, assign jobs. Have one player scout, another gather or hunt, and another handle repairs or hauling. Keep a shared retreat plan for storms and cold rather than splitting so far that nobody can help.
What the game does—and does not—establish
- Established by the store listing: fictional frozen post-apocalyptic setting; story-driven survival sandbox; cold, frostbite and storms as named threats; exploration, hunting, scavenging, crafting, machine repair, shelter restoration; technology-gated progress; dog companion; solo and online co-op for up to four total players; listed Steam features and PC requirements.
- Not established by the listing: real-world permafrost simulation; exact temperature or frostbite thresholds; detailed crafting recipes; shelter statistics; dog capacity or detection values; multiplayer scaling rules; performance at a specific resolution or frame rate; a permanent final feature set during Early Access.
Keeping those categories separate prevents a common mistake: using the scientific definition to infer mechanics the game has not claimed, or treating promotional feature descriptions as independently verified test results.
