Do Valheim Old Saves Work With 1.0?
Keep a Valheim save in 1.0 or start over: understand unexplored Deep North terrain, the new save system, achievements, and backup decisions.
Quick Answer
Yes. Old Valheim saves remain available in 1.0. New biome generation works properly in areas that have not been explored, so an old world and a freshly generated world may offer different Deep North terrain. Iron Gate recommends starting over for the full experience, but does not require it.
