Deep North fieldbook · reviewed Sep 27, 2026
Valheim 1.0
Deep North is live. This fieldbook starts with the decisions that can cost a save or a wasted expedition: world generation, unsupported mods, crossplay, save sync and the real Mechanical Spring route.
Available nowVersion 1.0 · Deep North · full crossplayDirect answer
Back up first. Choose the world second. Sail north third.
Old saves still load in 1.0, but new biome terrain only generates correctly in unexplored areas. Iron Gate recommends a new world for the intended experience even though continuing is supported.

Live facts, with community data labelled.
Iron Gate establishes the release, crossplay, save behavior and mod boundary. The Mechanical Spring recipe is identified as community-maintained data because the official 1.0 notes do not publish it.
