Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“This game has two game modes: Survival and Campaign. As the Survival mode is already fully playable, we think it is a great idea to let the players play it and take their feedback to improve the game while we work in the Campaign mode. All the feedback and improvements will be applied to the Campaign too.”

Approximately how long will this game be in Early Access?

“As this game can be expanded in a lot of ways, we will keep it as Early Access as long as needed. With that said, we expect to finish the Campaign mode in Winter of 2018.”

How is the full version planned to differ from the Early Access version?

“The Early Access game will start by including the Survival Mode. In several months, we will include the Campaign mode, the story mode, with hand-crafted levels, crazy NPCs, and lots of other fun features! The final release will include both the Survival and Campaign mode.”

What is the current state of the Early Access version?

“The Early Access game now contains the Survival Mode. In this mode, a random world is generated and the player must create a colony that can survive in an apocalyptic world for a set period of time.”

Will the game be priced differently during and after Early Access?

“Early Access will be cheaper than the final release. However, we have not finalized the price for the final release.”

How are you planning on involving the Community in your development process?

“We plan to be extremely involved with the community. We love community feedback! We already did this with our last game Lords of Xulima.”

New Version 0.9.2

Just a quick update to talk about the new version published 0.92 and some news about the incoming Level Editor.

New Version V 0.9.2
It is just a minor update. It fixes some problems and bugs and also improves the general performance. It also includes these new features:

Custom Keys

Now you can customize most of the keyboard commands available in the game. You can do it from the Options screen, under the controls section. You can even assign several keys for the same command if you like.

We have added some more achievements that make the Survival Game more challenging and spicy:

The Game Editor

We expect to release the game editor in about two weeks under Steam Workshop. With the game editor players can create and share custom levels. The editor will be updated from time to time, growing in added features.

These are the main features included in this first version:

- Full map creation: Theme selection, terrains, forests, mountains, ornaments...
- Adding any game elements: Buildings, Doom Villages, treasures to loot, ruins, units...
- Adding interactive elements, like displaying a message when a unit enter in a selected area, or creating Units (Infected) generators.
- Create your own story by customizing the start, game win and lose, game events, neutral characters that join your colony. All of these with your own style and writing.
- Full control of game events: Roaming infected groups, swarms, win conditions, send all infected to the Command Center, grant or remove resources to the colony...

What do you think? We are confident that you will create great and original levels with this first version. Here you have some screenshots:

And that's all for now. See you soon!

[UPDATE 12/11/2018]

We have delayed some weeks the launch of the editor as we have been improving it heavily. The reason is because we want to make sure that all levels and content created with the editor will be always compatible with all future new versions of the game. Also we have added some cool features that were missing in the previous version:

  • Custom Survival Levels: You can let the game to generate random maps (as the Survival Games) and just customize the narrative, events and scripts to offer your own Survival Experience.
  • Custom Scripts: We have improved this part a lot. You can now interact much more with the player (dialog, menus to choose options...), and a lot of cool things to make very interesting levels.
  • Multi language support: You can create multi-language custom levels to reach a wider audience.
  • Custom Pictures: Decorate your story and narrative displaying custom pictures to the player.
  • New Custom Level from Numantian: The 50 Days Challenge! A extreme and super fast survival game where you will need the help of the colony neighbors to succeed.

First we will activate the Workshop and Editor for the Test Branch. We will announce it here very soon. And after that (for 26-29th Nov) we will make it public for all players.

Campaign Development (I)


I hope you’ve had a great summer! It’s been a while since our last update. It’s not only because even the most devoted developers need to take a break sometimes, but mostly because we’ve been working hard on the game, making big changes as we develop the Campaign Mode. This, unfortunately, has prevented us from updating the Survival Mode with new content for now.

So with this post, we would like to inform you on the game development and what we’re currently working on.

The Campaign

When we originally envisioned They Are Billions, the Campaign was the main gameplay mode and the Survival was just conceived as a quick game for fun, played in a random scenario, that allowed us to test and balance the game. We decided to release it in Early Access on Steam at the end of last year, as the players who played the Survival Preview (the backers) loved it. To our surprise the success of the Survival mode was so great that we decided to improve it over time, as you surely know, by continually adding content and putting a lot of work on it. But then... what’s happening with the Campaign?

We’re now in a paradoxical situation in which the development of the Survival takes time away from developing the Campaign and vice versa. And both modes need to grow together since they have the same core. Otherwise, we’d end up having two different games. So now, it’s the Campaign’s turn, which is also a good thing, as we’ll include many of the features implemented in the Campaign to enrich the Survival Mode.

And How is the Campaign development going?

The Campaign development has been much more time consuming than we anticipated. We’re committed to delivering a great Campaign and not just a bunch of survival scenarios that you have to play in sequence. We want to add there all that is lacking in the Survival Mode, to have a perfect and rounded experience.

In the Campaign you’ll have a big World Map where you’ll be able to choose what kind of missions to play to reconquer a big territory from the infected. Every mission accomplished will unlock new missions, but be careful because infected swarms will block your path to new territories. You’ll have to destroy them with your personal Imperial Army.

These are the kinds of missions you’ll encounter:

- Colony Building: In this mission you have to build a colony on an outdoor map and achieve specific objectives (resist X days, get X colonists, get X resources...).

- Swarm Attack: You’ll need to grow a big army from the Empire using your Empire Points to hire your troops. Lead them against the swarm that’s blocking your advance on the map and reach new territories where you can establish new human colonies.

- Old Fortresses: This is a tactical-based mission. You’ll explore abandoned human fortresses with just a few units. In these Fortresses, you’ll discover secrets and valuable artifacts that will grant you advancements in Science, Technology and the Empire. These will boost your Colonies and your Imperial Army.

The Old Fortresses missions are themselves like a whole new game that we think will improve and enrich the experience. You’ll have to venture into these infected places with only a handful of warriors (and a Hero, but we’ll talk about heroes later). To survive, use the environment to your advantage. These fortresses hold the keys to you finding out how the world fell to the infection, with lots of lore and many other surprises along the way.

We have now new artists creating hundreds upon hundreds of new graphic assets for the game. Here’s a taste of what the Old fortresses look like. We hope you like the atmosphere:

Incoming Game Editor

We expect to release a game editor soon, so players can create and share their Survival maps with other players. This will be officially supported and will be integrated with the Steam Workshop too. We’ll talk about it more in the next update.

And that's all for the moment. Keep on fighting for the humans!

See you soon!

About This Game

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.

Survival Mode - Available Now!

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.

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!

Future Game Mode - Campaign

In the campaign mode, you have to help the surviving humans to reconquer their country. There are dozens of missions with different goals: building colonies, tactical missions, rescue missions... You can decide the path of progress and mission - research new technologies, advances and upgrades to improve your colonies and army. We are working right now on the campaign and we expect it will be available for Winter 2018. The campaign will be included for free to all the buyers of the Steam Early Access version.
