Headquarters: Cold War is an immersive turn-based strategy game that transports players to a hypothetical 1984 conflict between NATO and the USSR. Players can choose to command forces from either faction through two engaging campaigns and a selection of skirmish missions. The game emphasizes unit management, allowing players to build their forces, assign heroes, and level up units while utilizing powerful Headquarters skills to strategically outmaneuver opponents.

The game presents a true tactical challenge with its combat system, designed to be easy to learn yet difficult to master. Each unit is equipped with detailed armor configurations, making positioning crucial during battles. Additionally, the terrain and obstacles on the battlefield provide directional cover, while destroyed vehicles and buildings can create new tactical opportunities. Elements such as high ground advantages and destructible environments introduce verticality and unpredictability, enhancing the strategic depth of gameplay.
