Sakhal is the frozen volcanic archipelago introduced with DayZ Frostline, the game’s first paid expansion, released on 15 October 2024 alongside update 1.26. It is a self-contained official map, not a community mod, and it rewrites a lot of what you think you know about staying alive in DayZ. Here the temperature is usually below zero, food spawns frozen, and even the snow under your feet can poison you. This guide covers the terrain, where to head for loot and water, and how to actually survive the climate.
What is Sakhal? A frozen volcanic archipelago
Bohemia officially describes Sakhal as “a frozen volcanic archipelago located in the far east,” built around windy hilltops, snowy forests, messy settlements, vast ice fields and a massive naval base. Including the ice sheets, the playable terrain is roughly 105 km², which makes Sakhal the smallest official DayZ map. Don’t mistake small for forgiving — the dense layout and brutal climate make it one of the most punishing maps in the game.
The map is studded with hot springs and shaped by volcanic activity. That volcanic ash is more than scenery: it contaminates nearby snow and water, which is the root of the new Heavy Metal Poisoning threat covered below. If you’ve come from Chernarus or Livonia, treat Sakhal as a survival puzzle first and a PvP map second.
The cold: Sakhal’s defining survival threat
On Sakhal the ambient temperature is usually below freezing, so warmth management is a constant, active task rather than an occasional concern. Frostline expanded DayZ’s temperature simulation in two important ways. First, items themselves now carry temperature, so winter clothing insulates better than its summer equivalents and wet gear costs you heat. Second, food cools off based on server temperature and will eventually freeze solid if left out — meals progress through Hot, Warm, Chilly, Cold and Frozen states, and you generally want food at least Warm before eating it.
To stay warm, rely on heat sources such as a campfire, a gas stove, or sitting inside a car. Layered, dry, insulated cold-weather clothing is your baseline defence. Hot springs scattered across the map offer natural warmth too — but, as covered next, drinking from contaminated water is a trap. Note that Frostline also reduced cargo space in jackets, pants, vests and backpacks, so you carry less and have to plan loot runs more carefully.
Heavy Metal Poisoning: don’t drink the snow
The single most important Sakhal-specific mechanic is Heavy Metal Poisoning, contracted by consuming snow or water that volcanic ash has contaminated. Critically, the usual fixes do not work: boiling water and Chlorine Tablets remove germs but do not remove heavy-metal pollutants. To consume snow or suspect water safely, use a Filtering Bottle or take Chelating Tablets. Chelating Tablets are also the cure — take one at a time and let each wear off before the next. In its early stages the poisoning can clear on its own over time, but if it advances to its final stage untreated it becomes lethal. The safest water plan on Sakhal is to find genuinely clean wells, ponds and bottled drinks rather than gambling on snow.
Key towns and where to land
Sakhal’s settlements range from tiny fishing hamlets to substantial coastal towns. Named locations include Petropavlovsk-Sakhalskiy (one of the largest coastal settlements and a strong early-game hub for food, basic firearms, fishing gear and cold-weather clothing), along with Severomorsk, Aniva, Nogovo, Rudnogorsk, Dolinovka, Yasnomorsk and many more. Coastal towns are your fresh-spawn lifeline for the warm clothing and calories you need before the cold catches up with you.
Military and high-tier loot
The headline military objective is the large naval base that Bohemia calls out as a defining feature of the map, plus an airfield toward the southern part of Sakhal and a southern military peninsula where dynamic events like vehicle convoys and crashes appear. These high-risk zones are where you go for top-tier weapons, ammunition, military clothing and optics — but they’re also where other survivors hunt, so weigh the reward against the exposure. As on every map, dynamic events refresh, so circling back pays off. For a deeper look at military looting principles that carry over from the mainland, see our companion guide below.
| Sakhal feature | What it offers | Survival note |
|---|---|---|
| Coastal towns (e.g. Petropavlovsk-Sakhalskiy) | Food, basic firearms, fishing gear, warm clothing | Best fresh-spawn priority for warmth |
| Naval base | High-tier military loot | High traffic and exposure |
| Southern airfield / military peninsula | Weapons, optics, dynamic convoys and crashes | PvP hotspot; events refresh |
| Hot springs | Natural warmth | Nearby water may carry heavy metals |
| Contaminated snow / water | Emergency hydration | Use Filtering Bottle or Chelating Tablets only |
Food, water and new wildlife
Food on Sakhal is scarce and often spawns frozen, so you’ll spend time thawing meals before they’re edible. Hunting fills the gap: Frostline re-added hares and foxes and introduced new animals to the region, with reindeer among the wildlife to track across the snow. Fishing is reliable too — you can land Steelhead Trout and Pollack with a fishing rod, and catch shrimp using a small fishing trap. For getting around the archipelago’s islands and ice fields, the new rubber boats are the easiest vehicle to get running and let you cross open water between landmasses. Pair hunting with cooking over a fire and you solve food and warmth at the same time.
Sakhal vs. Namalsk: official cold map vs. mod
If you’ve heard people compare Sakhal to Namalsk, keep the distinction clear: Sakhal is official, paid DLC content from Bohemia, whereas Namalsk is a long-running community mod with its own separate cold and radiation systems. Both punish you for ignoring temperature, but their mechanics, items and servers are distinct. We cover the mod separately in our DayZ Namalsk guide.
Frequently asked questions
Is Sakhal free or paid?
Sakhal is part of the paid DayZ Frostline expansion — DayZ’s first standalone expansion (the Livonia map was its first paid DLC back in 2019) — released on 15 October 2024 with update 1.26. It is official content, not a mod.
How do I avoid Heavy Metal Poisoning?
Don’t drink untreated snow or contaminated water — boiling and Chlorine Tablets won’t help. Use a Filtering Bottle to consume snow safely, and keep Chelating Tablets on hand, since they both prevent and cure the poisoning.
How big is the Sakhal map?
Including its ice sheets, Sakhal is roughly 105 km², making it the smallest official DayZ map. Its dense layout and constant sub-zero climate make it feel anything but easy.
Survive Sakhal together
Sakhal rewards coordination — splitting up loot runs, sharing fires and watching each other’s temperature is far easier with a crew you trust. If you’d rather tackle the Frostline cold with friends on a world that’s always online, spinning up your own dedicated DayZ server gives you full control over settings, mods and who joins. Our DayZ server setup documentation walks through installation and configuration step by step.
