Game Information

Available on:PCJun 18, 2019

Developer: Numantian Games

Genre: Strategy

They Are Billions is a strategy game in a distant future about building and managing human colonies after a zombie apocalypse destroyed almost all of human kind. Now there are only a few thousand humans left alive that must struggle to survive under the threat of the infection. Billions of infected roam around the world in massive swarms seeking the last living human colonies.


Lead the campaign under the orders of Quintus Crane, ruler of the New Empire, and reconquer the lands devastated by the infected.

48 missions with more than 60 hours of gameplay.

Build fortified colonies to survive in infected territories

Destroy the swarms of infected with the Imperial Army.

Make your colonies evolve with more than 90 available technologies.

Explore the ancient human fortresses with your Hero.

Discover the story behind the apocalypse... how did the pandemic start?


In this mode, a random world is generated with its own events, weather, geography, and infected population. You must build a successful colony that must survive for a specific period of time against the swarms of infected. It is a fast and ultra addictive game mode. We plan to release a challenge of the week where all players must play the same random map. The best scores will be published in a leaderboard.


This is a real-time strategy game, but don’t get too nervous. You can pause the action to take the best strategic and tactical decisions.
In Pause Mode, you can place structures to build, give orders to your army, or consult all of the game’s information.
This game is all about strategy, not player performance or the player’s skill to memorize and quickly execute dozens of key commands. Pause the game and take all the time you need!


Build dwellings and acquire food for the colonists. They will come to live and work for the colony.
Collect resources from the environment using various building structures. Upgrade buildings to make them more efficient.
Expand the energy distribution of the colony by placing Tesla Towers and build mills and power plants to feed the energy to your buildings.
Build walls, gates, towers, and structures to watch the surroundings. Don’t let the infected take over the colony!


What kind of people would want to combat the infected?
Only the maddest ones. Train and contract mercenaries to protect the colony. They demand their money and food, and you will have to listen to their awful comments, but these tormented heroes will be your best weapon to destroy the infected.
Every unit is unique and has their own skills and personality – discover them!


Yes! They are billions! The world is full of infected creatures… they roam, smell, and listen. Every one of them has their own AI. Make noise and they will come – kill some of them to access an oil deposit and hundred of them will come to investigate.
We have created our custom engine to handle hordes of thousands of the infected, up to 20,000 units in real time.
Do you think your colony is safe? Wait for the swarms of thousands of infected that are roaming the world. Sometimes your colony is in their path!


If just one of the infected breaks into a building, all the colonies and workers inside will become infected. The infected workers will then run rabid to infect more buildings. Infections must be eradicated from the beginning, otherwise, it will grow exponentially becoming impossible to contain.


Prepare to enjoy these ultra high definition graphics. Our artists have created tons of art pieces: Beautiful buildings with their own animations, thousands of frames of animation to get the smoothest movements and everything with a crazy Steampunk and Victorian style!

It's a smartly designed game at its core, despite the distractions. Just like a lone zombie can bring about your demise, sometimes one strong idea is enough.

They are Billions is a great game that is lacking in content. The idea behind it – a survival strategy with "realistic" zombie mechanics – is fantastic and the actual mechanics behind it are well thought out and make for a deep and enthralling strategy, if one that may be a little too challenging for some. If that sounds great to you then being light on content may not matter, as there aren't many, if any other games that fit into this particular niche.

The lack of the campaign mode and the difficulties in its gamepad control do not make the consoles versions of They Are Billions the best, although its fun and challenging essence remains intact.
