About this game

The world has frozen over. The dead walk the ice. Your only hope lies beneath the streets.
In the aftermath of a catastrophic global freeze, civilization lies buried beneath endless snow. The surface is uninhabitable β€” and the frozen wastes are crawling with the undead. Deep underground, in the abandoned tunnels of a metro system, a handful of survivors cling to life. Welcome to Frostfall Metro, a post-apocalyptic simulation & strategy game where every decision means the difference between survival and extinction.
πŸš‡ Build Your Underground Haven
Transform a derelict subway station into a thriving fortress. Construct living quarters, farms, medical bays, workshops, and defense outposts. Manage resources, assign survivors to specialized roles, and research new technologies to endure the long, frozen night. Every tunnel you clear, every room you build, brings your colony one step closer to prosperity β€” or one step closer to the horde.
πŸš‚ Command the Armored Train
The legendary metro locomotive is your greatest asset β€” and your most powerful weapon. Upgrade the train with reinforced plating, mounted turrets, resource harvesters, and mobile labs. Send it on expeditions across frozen rail lines to scavenge supplies, rescue stranded survivors, and uncover the secrets of the old world. But beware β€” every journey attracts the attention of the undead.
🧟 Defend Against the Frozen Horde
Zombies pour into the metro through collapsed tunnels, ventilation shafts, and breached platforms. Set up chokepoints, deploy automated turrets, lay traps, and command your survivors in tense real-time defense battles. The horde grows stronger with every wave β€” mutated abominations, frost-armored elites, and swarming infected will test the limits of your strategy.
❄️ Survive the Eternal Winter
The cold is as deadly as the dead. Manage heating systems, insulate your tunnels, and ration food and water through brutal blizzards that sweep the surface. Send scavenging parties above ground during rare safe windows β€” but never stay too long. The frost claims everything, eventually.
βš”οΈ Forge Alliances or Conquer Rivals
You are not alone underground. Other survivor colonies compete for the same scarce resources. Trade with friendly factions, form alliances to face common threats, or dominate them through force and strategy. In the metro, trust is a luxury β€” and betrayal is always one stop away.
