Company of Heroes 3: Final Stand is a roguelite-focused spinoff that departs from Relic's classic WWII strategy campaign formula. Players choose from four historical factions and attempt to survive twelve increasingly difficult waves of enemy assaults, with the objective of keeping their headquarters intact throughout the entire encounter.

The game's core progression system begins each player with minimal military units and expands capabilities between waves through randomised upgrade selections. These selections include new unit types, passive bonuses affecting vehicle durability or infantry cover effectiveness, and active abilities that influence tactical outcomes. The variety created by different upgrade combinations means each playthrough develops distinct force compositions and strategic approaches, preventing repetitive gameplay across multiple sessions.
