They Are Billions — A Steampunk Survival Challenge

They Are Billions drops you into a grim, steam-powered future where humanity clings to life amid endless swarms of infected. As governor of a fledgling settlement, you must design and expand a livable colony while holding back waves of the undead in tense, real-time encounters. The experience blends long-term planning with immediate tactical decisions, forcing players to balance growth and defense to keep survivors alive.

Core systems and player objectives

The game’s loop revolves around several interconnected systems that demand attention and foresight:

Grow your settlement footprint, adding housing and infrastructure to support an increasing population.
Fortify your perimeter with layered defenses to stop mass attacks before they breach inner zones.
Manage raw materials and production chains so your builders and soldiers have what they need.
React dynamically during assaults, repositioning units and using abilities to blunt enemy advances.

What makes it engaging for strategy players

They Are Billions stands out by combining macro-level resource and city planning with high-pressure micro-level combat. Its narrative tone and atmospheric visuals heighten the stakes, while unforgiving difficulty rewards careful preparation and adaptive thinking. Fans of deep strategy will find the need to anticipate threats and optimize layouts especially satisfying.
