They Are Billions

Game Introduction

They Are Billions is a survival, city-building game that blends real-time strategy and tower defense, developed by the Argentinian indie studio Stdion Pixel. Released in 2019, the game features a steampunk aesthetic. Players assume the role of a survivor leader in a post-apocalyptic, Victorian-era steampunk world overrun by a zombie virus. Your task is to lead humanity's last survivors to establish a colony and fend off endless waves of the undead. The story is set in a parallel Victorian world where a mysterious virus spreads rapidly, turning the infected into frenzied zombies. Players must choose a location in the zombie-infested wilderness to build a colony, gathering resources, researching technology, training armies, and constructing defenses to withstand wave after wave of zombie attacks, fighting for humanity's hope of survival in the apocalypse.

Game Features

Massive Horde Scale The "Billions" in the title is no exaggeration. The game supports rendering thousands of zombie units simultaneously. Players can witness hordes of thousands of zombies swarming across the map like a dark tide, a visual spectacle that delivers unprecedented tension and pressure.

Steampunk Aesthetic The game employs a unique steampunk art style. Buildings, weapons, and vehicles are imbued with the spirit of the Victorian Industrial Revolution. The combination of rusted gears, steam-powered machinery, brass piping, and Victorian architecture creates a post-apocalyptic world that is both retro and imaginative.

Procedurally Generated Maps & Missions Each map is procedurally generated, including terrain, resource distribution, and zombie placement, ensuring a unique experience every playthrough. The game offers multiple modes, including Free Build, Survival Challenge, and a rich Campaign with various missions.

Deep Strategy Systems Players must balance economic development with military defense and plan city layouts wisely. Interconnected systems like resource management, tech tree research, building upgrades, and army composition require comprehensive strategic consideration.

Extensive Buildings & Units The game features dozens of building and unit types. From basic resource-gathering facilities to high-tech defense towers, and from standard infantry to powerful steam tanks, players can freely mix and match according to their strategic needs.

Gameplay

Colony Building Players must first select suitable land to establish a colony. The game offers various terrains like plains, forests, hills, and lakes, each with unique advantages and limitations. Players build houses to attract workers, construct resource-gathering facilities for basic materials like wood, stone, gold, and food, and must carefully plan the layout of different functional zones.

Resource Management Multiple resources require management: Wood and Stone are basic construction materials; Gold is used for trade and hiring workers; Food sustains the population and enables growth; while Oil and Power are energy sources for advanced technology and defenses. Players must find a balance between expansion and development to avoid colony collapse from resource shortages.

Technology Research By building Research Centers, players can unlock various technologies, including more efficient gathering methods, powerful military units, advanced defensive structures, and passive skills that improve overall colony efficiency. The tech tree design encourages experimenting with different strategic paths.

Defensive Construction Defense is a core gameplay element. Players can build various defensive structures like Machine Gun Turrets, Cannon Turrets, Flamethrowers, and Electric Fences. Each defensive facility has unique attack methods and strengths, requiring strategic placement based on enemy types. Walls and traps are also vital components of the defense system.

Army Training Beyond passive defense, players can train various military units for active operations. Infantry, Snipers, Rangers, and Tanks each have distinct characteristics. Players must form combined arms forces to actively clear infected zones within the hordes and expand the colony's safe perimeter.

Horde Defense At regular intervals, massive zombie hordes will attack. Players must prepare thoroughly before they arrive, allocating resources and manpower effectively to ensure defenses are intact and armies are fully manned. At critical moments, players may even need to take direct command of the battle, making rapid decisions.
