Quick answer
Official facts confirmedValheim 1.0 launches September 9, 2026.
The update is free for existing owners and adds the Deep North endgame. Old saves continue, crossplay spans every launch platform, and achievement tracking starts only after 1.0 is downloaded. Final Deep North progression, item, and boss details are still launch-day facts.

Player impact
Three decisions sit behind the headline
Your old world can continue
New content generates properly only in unexplored areas. Choose between preservation and a clean map before opening a valued save.
Make the world decision →Achievements start from 1.0
Existing characters and worlds can earn achievements, but earlier feats are not awarded retroactively.
Check achievement eligibility →Mods are not guaranteed
Iron Gate does not officially support mods or guarantee launch compatibility. Preserve an unmodified fallback before updating.
What is not confirmed yet
The final Deep North boss path, complete resource and crafting lists, exact achievement list, platform-specific interface details, and release-build performance need final patch notes or direct launch evidence. The FAQ also says 1.0 does not include an Ocean biome overhaul.
A creature, weapon, or location appearing in official footage confirms that it was shown—not its final stats, recipe, unlock condition, or progression role.
