About They Are Billions

They Are Billions is a real-time strategy and colony-building game with pause. Players expand a settlement, manage food, energy and workers, and build defenses because a single breach can spread infection through the colony. Survival mode culminates in huge final waves, and a campaign adds missions and tech choices.
