Valheim leaves Early Access on September 9, 2026, and the Deep North arrives with it. The question filling every Valheim Discord right now is whether the world your group has poured 400 hours into still counts. Here is the honest answer, straight from Iron Gate's own 1.0 FAQ rather than from speculation.
Your Save Is Safe. Your Map Might Not Get the Deep North.
Two facts, both confirmed by Iron Gate:
- "Your old saves will still be where you last left them, and you can continue to play with them if you like."
- "Biome generation will only work properly on areas that have not yet been explored."
So nothing is deleted and nothing is forced. But the second line is the catch. Valheim writes terrain into your world file the first time somebody loads that part of the map, and it never rewrites it. If your longship has already been to the far north, that ice is baked in as the old placeholder version and will stay that way. If nobody sailed up there, those tiles are still blank and will generate as the real Deep North the first time someone arrives.
Iron Gate's own recommendation is blunter than the mechanics: "We always recommend that you start the game over from scratch to get the best possible experience." Asked directly whether you can head for the Deep North on an old save, their answer is that you can, but they still suggest starting over. That is worth reading carefully. It is a recommendation, not a requirement, and Iron Gate frames it as general advice for the best 1.0 experience, not as something limited to the northern edge.
The Other Things That Change on September 9
- Achievements start from zero. Tracking begins the moment you download 1.0. Nothing you did before launch counts, and a character that has used cheat commands carries a permanent flag that blocks unlocks entirely.
- Mods will break. Iron Gate is explicit that there is no official mod support and no guarantee that anything works at 1.0. Plan for a vanilla launch week and update your BepInEx stack afterwards.
- Crossplay covers everyone. PlayStation 5 and Nintendo Switch 2 join PC and Xbox, with crossplay between all platforms. Your dedicated server does not care which one a player is on.
- Capacity is unchanged. Iron Gate states 1.0 is a game for 1 to 10 players.
On a Server, It Is Not an Either/Or
This is where a rented server beats a friend's PC. A dedicated server holds as many worlds as you want, so the real answer for most groups is "both". Keep the old world with the base you love, create a fresh 1.0 world for the Deep North, and switch between them whenever the mood changes.
In the DoomHosting panel that lives in the Worlds tab. New world from seed writes a brand new world with the seed you pick and points the server at it, and the terrain builds on the next start. Your old world stays in the list underneath, untouched, and Make active switches back at any time. No file editing, no FTP, no deleting anything.
Two things to do before launch day, in this order: take a backup of your current server from the Backups tab, then create the new world so it is ready to go. If the update lands badly, the backup is the whole difference.
