FREIKORPS is a simulation game depicting a hypothetical invasion of Germany by the Soviet Union’s “Red Army of Workers and Peasants” in 1920. The game is designed for two players, one representing the irresistible forces of proletarian revolution (the Red player), and the other the impervious alliance of anti-Bolshevist forces that would have been arrayed to oppose such an invasion (the White player).

The game begins just after the Red player’s forces have won the Battle for Warsaw in August 1920. Sensing that the time is ripe to “carry Revolution to the rest of Europe on the points of Red bayonets,” the leadership of the Soviet Union has decided to seize Berlin, capital of a Germany in political and economic disarray. However, it is already mid-summer and the Soviet Union cannot sustain a military effort of this size past the onset of bad weather at the end of October. The Red player has just ten weeks to change the course of world history.
