Build a Soviet superpower across three new biomes: the scorching desert, the unforgiving tundra, and the lush tropics, each with its own challenges and opportunities. The spirit of socialism knows no bounds!
Establish a glorious nation from the ground up on unpopulated maps, or explore populated maps that feature existing small towns with architecture fitting their respective biomes, begging to be united by a visionary leader.
Contend with limited access to trees in the desert and the resulting demand for localized logging around the minimally available wet soil. Prepare for the logistical challenges of long distance hauling, whether from distant oases or foreign trade.
Brace for longer, harsher winters in the tundras by investing more heavily in the appropriate sectors – a shorter farming season strains your agricultural sector as heating services struggle in the frigid climate.
Brave the monsoons of the tropics, where road conditions will suffer under the immense pressure of precipitation. Traffic and transportation will be slow-going, and as a result you must plan around the reduced flow of industry and commerce alike.
Challenge yourself with unique biomes that allow you to explore new opportunities and experience new struggles as you build a powerful republic in some of the harshest environments on Earth.
