FUSE

FUSE is a Unity Mod Manager modding layer for Railroader. It loads FUSE data packages — route extensions, asset packs, audio packs, track graph changes, world scenery, operations, and progression data — and provides drop-in compatibility for legacy Railloader, Strange Customs, ConfusingSupplements, For Your Convenience, and Alina's Map Mod packages.
