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 Spring 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.”

Big Update! The Six Wonders


Here’s the teaser video we’ve prepared to announce The Six Wonders. Hope you like it!

The Six Wonders are the biggest and most amazing ones you can build for the colony. But, as mighty as they are, they’re also really expensive to build. Tons of resources are required for both researching and building them. In return, they grant very special features to the colony, and also increase the final score with extra victory points.

You can only build one of each kind in the same map. Building all of them can be challenging or almost impossible, but that's part of the strategy. If you have the resources to build just one, chose carefully which will suit your colony best, given the current map, your resources production...

The Lightning Spire

This portentous structure reaches toward the sky, capturing the energy of lightning for the colony. In addition, it extends the power supply, acting as a huge Tesla Tower.

  • Energy Supply: +800
  • Energy Transfer Radius: 30
  • Victory Points: +1500

The Atlas Transmutator

No one knows how it works, but this extraordinary and smoky metal spawn is capable of transforming common materials into precious oil.

  • Oil Supply: +40 (by transmutating 20 wood, 20 stone and 10 iron).
  • Victory Points: +2000

The Victorious

This unbreakable bunker stands as the most amazing symbol of the victory of humanity against the infected. It's a beacon of hope and courage for everyone in the colony.

  • Colonists Hope: +20% gold generation for the surrounding dwellings.
  • Unbreakable: Defenses Life 8000, Armor 10.
  • Victory Points: +2000

The Academy of Immortals

In this glorious academy, the most famous heroes train the army to battle with the skills and courage of experienced veteran soldiers.

  • All army units and new units trained are veteran.
  • Victory Points: +1000

The Crystal Palace

This magnificent architectural wonder generates its own climate control environment, where the best crops bloom and thrive, feeding the colony even in the most barren lands.

  • Food Supply +800 on any terrain.
  • Victory Points: +1500

The Silent Beholder

It’s the most precise and complex machine ever created. The Beholder is installed on top of the Command Center revealing the entire map. Nothing can escape its prodigious eye.

  • Reveals all the map and enemies permanently.
  • Victory Points: +1500

Finally, here goes a screenshot to show you how the Wonders look in the colony:

New Version 0.8

Of course, all the new features we talked about in our last update are now available: Flat mode (F4), World Capture (F10), the new 30 Mayors, Italian language, the new balancing tweaks, and much more.

By the way, as the Flat Mode has proven to be very helpful, we’ve improved how it’s activated. In addition to using the F4 key, you can use any extra button you have on your mouse, other than the left and right ones, to activate this. For example, you can use the central button that is usually available by pressing the wheel.

What's Next?

Now, we want to put most of our workforce into developing the campaign and finishing the game. In the meantime, some of the new campaign content may be added to the Survival Mode, such as new map themes, new infected... and new features.

As many players have requested, we’ll improve the frequency of our updates to two or three weeks at most. We’ll share more about how the development is going, and tell you, the players, more about They Are Billions.

We hope you like this new update! Looking forward to watching those mega screenshots of your colonies with your amazing wonders.

See you soon!

Development Progress


As you know we are working on a big update for They Are Billions (V.0.8) with The Six Wonders, that we expect to publish on the 5th of May. Yes, it has been delayed, sorry about that! The main reason is that we have to translate all the new stuff into 12 languages which pushed back the release dates and also requires extra testing time.

Meanwhile we have used this time to add more features suggested by you, the players, to improve many aspects of the game. Apart from the Six Wonders, which we will go more in detail in our next post, we want to talk about the new features of the upcoming 0.8 version.

New Language Available: Italian

Finally, we have finished the translation to Italian and it will be included in the next version 0.8. They Are Billions is now available in twelve languages!

Flat Mode (F4)

This is really helpful! You can toggle the Flat Mode with the F4 key. When activated, mountains and forests will be displayed just as flat coloured cells, allowing you to see what’s behind them, making it easier to build near those hidden parts of the map.

More Building Assistance

The cells that are in the map limit, where building is not allowed, will be displayed without energy so that it is much easier to know where the limit is and plan your defences accordingly.

Also, when building, all existing objects will turn semi-transparent as the mouse moves over them, to improve the visibility behind them.

Chasing Command for Groups of Units

You will really love this feature! Now, all units in the same selection slot will automatically go in a group formation when they are in the chase command mode. Just select a group of units, save them in a slot with right click and then activate the command chase.

The Inn 2.0

The Inn has been improved in several ways. It’s influence radius is now bigger, and It’s building margin reduced by one.

Mercenaries come to the Inn every five days, except the first ones which will come after just one day. Also, the number of days remaining for new mercenaries to arrive and the percentage of prestige of the Inn is now shown in the features panel. The more prestige, the more powerful the group of mercenaries will be.

30 New Mayors!

We have added 30 new mayors to add more variety to your colonies. Also, if Mayors that bring resources to the colony (for example 200 wood) provide an excess that cannot be stored in the warehouses, they will be placed as bonus items next to the Command Centre, so you can use them when needed. This can be very useful when building the ultra-high expensive Wonders.

Lots of Balancing Improvements

We have made lots of balancing tweaks, so many that we cannot cite them all here. We have improved the Soldiers (that were not so useful compared to other units). Soldiers now level up faster, they do a bit more damage, they regenerate full life in just 24 seconds, their Armour is better and gives 50% more resistance to fire and venom.

Also, Lucifers do more damage, have more health and regenerate full life in just 12 seconds, and they have 75% resistance to venom.

Titans attack radius has been increased by 20% and deal more damage, also they have more life and Armour, but they are more expensive.

Many of the structures have also been tweaked, so now the game feels much more balanced. Also, the map generation is better now and the map scenario types have also been improved.

Now, more than ever, you will have a wider range of strategic options to fight the infected and develop a successful colony.

Units Health Regeneration

We have improved this mechanic to make it more relevant in game. First we have added a tooltip for the Life text in the selection panel which will tell you about the life regeneration rate of the unit. Units start to regenerate health after two seconds without having received any damage. It will then regenerate a fixed number of life points every second:
  • Ranger: 1 point / second. Full life in 60 seconds.
  • Soldier: 5 point / second. Full life in 24 seconds.
  • Sniper: 1 point / second. Full life in 150 seconds.
  • Lucifer: 40 point / second. Full life in 12 seconds.
  • Thanatos: 3 point / second. Full life in 83 seconds.
  • Titan: 8 point / second. Full life in 100 seconds.

Press F10 to take a Mega Screenshot of your entire colony!

This is just amazing! Have you ever wanted to show off your colony to your friends? Does your colony look amazing with your Six Wonders? Have you won the game without using walls or with any other crazy condition and you want to show it to the world? Now you can! :)

Just press F10 whenever you like and the game will render an ultra-big image of the full map. This is especially amazing when the final horde comes to the colony as all the map is revealed.

You can configure the resolution of the image in the options screen, the highest value being 256 mega pixels!! Just check this.

We hope you like the new changes for gameplay and the Survival Mode. Of course, we keep on working on the campaign secretly behind the scenes. After this big update on the 5th of May, we will share with you more details about the highly anticipated campaign.

Thank you all for your incredible support! 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 Spring 2018. The campaign will be included for free to all the buyers of the Steam Early Access version.
