What if communism lasted forever?

In this gripping alternate history DLC for ICBM: Escalation, the Soviet Union emerges from the Second World War stronger, smarter, and far more ruthless. The politburo has tightened its grip, forged a stable superstate, and is ready to reshape the world, by diplomacy, domination, or devastating nuclear fire.

Set in 1950, just five years after the end of the Great Patriotic War, Endless October plunges players into a world where the Cold War burns hotter and longer. The USSR detonated its first nuclear bomb only four years after the U.S. and now, Korea becomes the first major flashpoint in a decades-long global struggle.

Take command of the Soviet Union and lead it through a sprawling campaign that spans the 20th century and beyond. Forge alliances, provoke conflicts, and rain destruction on capitalist enemies as you aim to raise the Red Banner over every continent.

Long live the revolution. Endless October has begun.
