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.

Game Modes

Campaign: The New Empire - Available now!

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?

Survival Mode

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 100 days 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.

Real Time with Pause

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 your Colony

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!

Build an Army

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!

Thousands of Units on Screen

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!

Prevent the Infection

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.

Beautiful 4K Graphics!

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!

We are very happy to announce that They Are Billions is available for XBOX One (right now) and PS4 on July 9th. The time has come for console players to also enjoy this RTS. Although for the moment it’s only available in the Survival mode, we will also bring the Campaign mode to this console in the near future.

An RTS on consoles?

Indeed, there are not many RTS games in consoles. This genre is mostly exclusive to PC because its game mechanics make it essential to use a mouse and keyboard. But at Numantian Games we have accepted the challenge. First of all because we truly believe that console players can also enjoy this exceptional game genre that we like so much. Second, They Are Billions within the RTS has also created its own sub-genre, a new style that has managed to bring many players who had never before played this type of games, and have enjoyed it as much as the more veterans players. In the porting we have tried to be 100% loyal to the PC version. We want the game experience to be the same. Along with Blitworks, our porting partner, a huge effort has been made to achieve a game speed equivalent to the PC, as this game uses CPUs and multicore super intensive. Few games can boast of handling 30K units in real time, each with fully independent AI. We also had to work to adapt the game handling to the console interface and we have implemented two play modes:


In this mode, the cursor and the camera can be moved with the analog joysticks. We have also enabled many shortcuts for the most typical actions that greatly improve the speed of handling. They Are Billions was always conceived as a game where strategy comes first (over player's performance) and that's why you can pause, so you can take your time and decide your strategies and tactics. This allows that in consoles, even if it is a little more uncomfortable handling with gamepad, the player establishes the preferred pace of play.

Mouse and Keyboard

The new consoles allow you to use any normal USB or Bluetooth mouse or keyboard and, of course, they are both supported by They Are Billions. In this case the gaming experience is exactly the same as in the PC version. Even you can perfectly play with mouse while using the gamepad for shortcuts. And that's all for now. If you have console gamer friends you can tell them that: "The zombie apocalypse, has arrived!" And if anyone is curious to see how has been the development on consoles here you can see our friends from Blitworks in action:

See you soon!
