Set in an alternate history where the United States emerged from World War II with more than victory, this expansion’s campaign imagines a nation unchecked by opposition. There’s no Korean War. No arms race. No balance of power. Instead, the United States has poured limitless resources into its nuclear program, creating a war machine unmatched by no rival.

Armed with a monopoly on nuclear weapons and driven by an insatiable thirst for control, America rises as a self-proclaimed guardian of freedom whose democracy serves as a cover for ruthless domination.

Endless October explores this “what if” scenario across 11 missions, beginning in 1950 and extending into the near future — the year 2047.

In this DLC, the Soviet Union emerges from World War II strong, cunning, and ruthless, determined to reshape the world through diplomacy, domination, or nuclear fire. Players will be tasked with raising the Red Banner over every continent, forging alliances, and thriving amidst war and conflict.

The expansion also introduces new Soviet and Russian-style player portraits, and marks the debut of cosmetic loadouts. Depending on the nation they’re playing, players will see appropriate counterparts on the battlefield — their Leopard 1s might appear as T-62s, their F-22s as Su-57s, and so on. Units are automatically represented using faction-specific models to better reflect the historical and stylistic context. Whether simulating Soviet dominance or leading a modernized Russia, players’ forces will look the part.

Endless October is out now on Steam, with the base game, ICBM: Escalation, on sale at 10%.
