Workers & Resources: Soviet Republic - Biomes is a DLC for the city-building simulation game Workers & Resources: Soviet Republic. It adds three new biomes: desert, tundra, and tropics. Each biome presents unique environmental challenges and opportunities for resource management and logistics, including limited resources in the desert, harsh winters in the tundra, and monsoons in the tropics. Players can build on unpopulated maps or integrate their republics with existing towns on populated maps within these new environments.
