Expand World is a Valheim modpack that lets you add new biomes and deeply customize world generation. Adjust world size, tweak your world seed, and enable background minimap generation for smoother exploration.
The Expand World pack includes modules like Expand World Size, Rivers, Data, and Events, each with dedicated GitHub documentation. Some features are server-side only, while others must be installed on all clients and the server. Existing configs and YAML files are reused automatically, and “Legacy Generation” helps when biome borders change. ⚙️
