Headquarters: Cold War is a fast-paced turn-based strategy game set in a hypothetical conflict between NATO and the USSR in 1984. Commanders can play as either side across two plot-driven campaigns and a variety of skirmish missions. Build your force, assign heroes, level up units, and use powerful Headquarters skills to outsmart the enemy and change the course of modern history.
Campaigns and multiplayer
Play through two campaigns (NATO and USSR) with 10 missions each, test your tactics in Skirmish battles against improved AI, or challenge friends in online multiplayer with up to 4 players. Cooperative 2v2 battles are supported, along with asynchronous play through Slitherine's CombatHQ system.
