Valheim 1.0 Is Here: What the Deep North Update Adds

Valheim’s Early Access run is over. Version 1.0 landed on September 9, 2026, five and a half years after the game first appeared on February 2, 2021, and it brings the Deep North — the frozen biome at the top of every world map that has sat empty since launch. It also brings a new boss, a proper achievement system, two new consoles, and a higher price tag.

Quick answer: If you already own Valheim, 1.0 downloads as a normal update at no extra cost and your old characters and worlds still load. Back up your world files before you launch it, and create a fresh world if you want the Deep North and the other new world generation to appear correctly.

Valheim 1.0 platforms, price, and download size

Iron Gate and Coffee Stain Publishing shipped 1.0 everywhere at once. There was no staggered rollout and no public test branch beforehand, so every player got the same build on the same day. The console lineup now includes PlayStation 5 and Nintendo Switch 2 for the first time.

The price increase applies only to new purchases. Anyone who bought the game during Early Access keeps it at what they paid.

Deep North biome: snow, ice, and where you can build

The Deep North is the last biome in Valheim’s progression, and its weather is a mechanic rather than scenery. Deep snow covers large stretches of ground, and you cannot settle on it until it is cleared. That means crafting a Snow Shovel and digging out a footprint before a single wall goes up. Snow also gathers visibly on rooftops during storms, and it leaves footprints without slowing you down.

Ice behaves differently again. Frozen lakes are slippery enough to slide across and easy to fall on mid-fight, ice shelves link islands together along the coast, and frozen surfaces can be smashed — either by hand, with an Ember Charge, or by ramming a ship straight into a sheet to break it apart and drop whatever was standing on it. Collected snowballs feed into a new Ice Maker station that turns them into buildable Ice Blocks, and snowballs can also just be thrown at friends.

Two dungeons sit inside the biome. The Winding Tunnels are entered through openings in the large houses of abandoned villages, and hold Frostcore, Luminous Larvae, and the Moulds used for late-game crafting. Mörkhalla is gated behind fortress-like structures and needs an Intricate Key to open. Other new locations include stave halls, ice ponds, memorial sites, and the Forge of Potential, a hidden forge where the idols scattered around the world are used to push gear past its normal ceiling.

1.0 also touches the rest of the map. Seeds can now generate alternate versions of earlier biomes toward the outer edges, such as Rocky Birch Meadows and a Deforested Black Forest, and two world events have been added — one announcing that the Jotun have found you, another warning that something is emerging from below. The Ocean biome received nothing new.

New creatures, enemies, and the Deep North boss

More than ten creatures arrive with the update, including one new boss, Kall Fimbulbringer. Some of them are hostile, some are livestock, and one is a mount.

Nord, Frostfire, and Thunderblood weapons, plus four armour sets

Over 40 weapons come with 1.0, and most of them are organised into three parallel tiers that each cover the full weapon roster. Nord gear is cast from Bloodgold at the Frost Foundry using Moulds recovered from the Winding Tunnels, and each Nord weapon can be upgraded with two gemstones. Bloodgold itself is smelted from Petrified Tissue, the raw material left behind by a shattered Gammeltroll.

The Grappling Hook is unlocked back in the Mistlands, has unlimited uses, and handles both climbing cliffs and swinging across gaps. The staves cover more specialised roles — Spirit Caller summons a ghost wolf, bear, or moose to fight beside you, and Northern Vengeance is an upgraded Staff of Protection that damages anything striking the shield instead of simply absorbing the hit.

Building gets a similar expansion, with more than 80 new pieces. Highlights include working drawbridges, steeper 67-degree roof pieces across several material styles, Scalewood structures made from Timberwood, Ice Blocks, and a Wardrobe that holds considerably more than a Black Metal Chest. New crafting stations and extensions include the Frost Foundry, the Frigid Kiln, a Smoker for the cauldron, Smith’s Aprons for the Black Forge, and a Standing Loom for the Galdr Table. Over 20 food items were added too, with lingonberries, kale, oats, and poteitr among the new ingredients.

Achievements start tracking from install, and cheats lock them

Valheim now has 53 achievements, each with its own icon and unlock condition, and some of the objectives are hidden. Nothing you did during Early Access counts. Tracking begins the moment 1.0 is installed, so an achievement for killing Eikthyr requires killing Eikthyr again even if you have done it hundreds of times already.

There is a hard separation between cheated and clean saves, and it is worth knowing which actions are permanent before you open the console.

Old worlds still work, but a new one generates the Deep North properly

Your existing saves are untouched by the update and sit exactly where you left them. Old worlds do receive the new content, with one catch that decides everything: biome generation only applies to terrain you have never visited. If you already sailed and mapped a chunk of the frozen north, those tiles will not fill in with villages, dungeons, or resources. Iron Gate’s recommendation is to start over.

Note: a new run is no longer identical to the old one. Haldor sells Deeper Pockets and Wider Pockets upgrades that expand your inventory, every hair and beard style is unlocked from the start, and Ashlands enemy spawn rates have been rebalanced.

Crossplay works everywhere, cross-progression mostly does not

Every supported platform can share a session. Windows, Linux, Mac, Xbox One, Xbox Series X|S, PS5, and Switch 2 players can all join the same server, with the 1–10 player cap unchanged.

Save syncing is far narrower. Xbox players can reach their saves on PC, but only through the Microsoft Store version of the game. No other combination moves characters or worlds between systems automatically, so playing with a friend on another platform does not mean carrying your Viking there.

Performance, interface changes, and mod support

1.0 ships on an upgraded Unity engine with a rebuilt save system that splits world data into chunks, which cuts how much data is written at once and is designed to survive a failure mid-write. Saving is faster, and the microstutters that hit when zones load in and out of memory have been reduced. A new Draw Distance graphics setting lets you shorten the simulation range for performance or extend it for the view. Very large settlements are the exception — Iron Gate has said these particular changes will not do much for sprawling builds, and that performance work continues after release.

On the interface side, the hammer and serving tray menus were reworked, every build piece description was rewritten, and an optional HUD window shows which player placed each piece. Capes and cloth now use the Magica Cloth system, player movement animations were redone, and the update adds new music, cinematics, dreams, runestones, and Munin dialogue.

Mods remain unofficial. There is no built-in mod support, no Steam Workshop integration, and no console modding, and a version jump this large usually breaks existing plugins until their authors rebuild them. Treat every mod as incompatible until proven otherwise.

What happens next is the one genuinely open question. Iron Gate has committed to bug fixes and quality-of-life work after 1.0 but has not said how long that support runs, and has not confirmed whether any further content is planned. The Deep North closes the biome progression the studio started building in 2021 — everything past that point is unannounced.
