Update #6: Defend your colony!

First, we'd like to show off the main theme that our composer Nicolas de Ferran has created for They Are Billions. As you can see in the video, the theme is played during the main menu of the game. We have called it: "An Ocean of Doom". Hope you like it!

Today, we will talk about one of the most important parts of the game which is defending your colony from the infection. We are sure every player will follow their own strategy, so we won't tell you what to do but instead, tell you what you can do. Most of the strategy techniques must be researched first in the workshops so you will have to think carefully on which of them you invest in. There are a lot of tactics and combinations. Experiment with all and have fun!


Mountains, forests, cliffs, lakes, ruins and many other geologic elements are part of the world map. Though you cannot do much with them, you can decide to expand your colony around the most protected terrains. The less exposed the colony, the easier it will be to defend it. At the same time, you will want to be near resources, so deciding where to extend the colony can be the most important decision to survive.

Your Army

The first few units in which you start the game with will be your unique defense in the beginning. Units can patrol between two points and will kill any enemy that they find in their way. The first units can be enough for dealing with roaming infected that come close to the colony, but you will need many more to stop bigger groups or defend against the dreadful swarms. The advantage of the army is clear, they are dynamic. They can move and be placed wherever you need them while all the rest of defense elements are static. If you need to extend the colony, you will have to destroy them and rebuild them again in a new place.
Units can also cure themselves with time, while all other structures must be repaired when they are damaged by spending gold and resources.

Walls and Gates

Blocking all access into your colony with walls is always a great idea. However, walls are not cheap, especially in the beginning. You will have to decide carefully where to build them. Use the terrain to your advantage. Also placing gates will allow your soldiers to pass through and enter and exit your colony. But do not worry, the gates open and close automatically for allies. Your enemies will have to destroy them to enter. Walls are passive defense elements. They block access from the infected. However, the infected can destroy walls while they trying to reach the colony. To survive, you will also need offensive attack elements like units, traps or turrets to kill them. You have lots of strategies here. For example, you can make several walls rings that surround your colony so if the infected reach the colony, they will be contained in the next ring.

Army Towers

Place your units in these towers and they will gain a big bonus to their sight and attack radius. They work perfectly with the walls. Placing a few towers wisely can protect all your colony frontiers without having units patrolling. Towers are a great way to protect your units, as these towers are very strong. The downside is, the same as the walls, they are expensive. When you wish to extend the colony, you will have to destroy them and build new ones. The towers also need units inside, otherwise, they are just big passive walls.


On the ground, you can place traps such as stakes, metallic wired fences, or even mines. Though there can be billions of infected, they are not very smart when deciding their path into the colony. The stakes and metallic traps will damage the infected while they walk over them. If you build many of them, they can destroy large groups of the infected. The downside is that the stakes are also damaged while the infected come though, so you will have to repair them from time to time. The mines are different. They explode and can kill even the strongest infected easily. They are expensive, so use them carefully. Of course, none of these traps can harm your units.
There are a lot of strategies to using traps: place mines in front of your walls, place them in a safe place and attract the infected to them by using your fast rangers, or surround your more vulnerable buildings just in case the infection reaches the colony, it won't spread as fast...

Guard & Radar Towers

These towers allow you to watch from much farther away than with just units or other structures. This is a very big advantage. Detecting roaming groups or big swarms much earlier can make a difference, as you will have more time to move your army or even place traps. Also, they will unveil a big part of the map that surely you have not seen before. This allows you to discover resources or safe places to extend the colony.

Attack Towers

The Great Ballista, The Executor and more... They are very sophisticated and expensive to research and build but they are also very powerful. They have a very large attack range and produce extraordinary damage. But, in contrast with the other structures, they need some workers and energy to operate. Be careful where you place this powerful machine. If the infected manage to break into them, the workers inside will now be infected and your enemy in combat. At the same time, if they lose their access to energy because the infected have infected a nearby Tesla Tower, they won't work at all.

Development and the Incoming beta access

Right now we are working very hard on polishing the Survival mode of the game. Though the game is fully playable and looks very good, there are several small things we want to polish before creating the first gameplay video or releasing the beta. Most of the things are just small issues like some missing sounds, improving the in-game help, adding tips, other cosmetic elements, some optimization, and of course, finding and fixings some mini-bugs. All of these things can take some time, so we expect that the next update in about two weeks will include the gameplay video. Then, perhaps in the week to follow that, the beta will be available through our website.

See you soon!

Update #5: The Villages of Doom

Greetings! First of all, we have created a small mini teaser for They Are Billions. It fits really well with the mood of the game. We hope you enjoy it. Please, share it with your friends if you like it!

Today we will talk about a new element of the gameplay: The Villages of Doom.

The Villages of Doom

It is said that when the infection spread across the mega cities of the 22nd century, thousands of the surviving families escaped and they settled in the small villages of the country to avoid the infection. They call them Villages of the Alive. They felt safe for some time as they expected the infection would remain in the cities. After all, the infected weren't very smart beings. But when the mega cities collapsed and no human life remained, the infected did not stay there any longer. Swarms of millions of infected left the cities and started to roam around the country like a plague of locusts. And perhaps it was by some far echoes from the villages brought by the wind or perhaps small particles of human smell in the air, the swarms managed to find the villages.

The new settlers dug deep bunkers under their houses to hide from the infected but it was useless. The infected turns crazy when there are humans near and can break everything with just their hands.

Ultimately, the villages turned into nests of the infected. The new humans of the colonies call them Villages of Doom and always avoid them. It seems the infected are surprisingly comfortable in those nests, staying there quiet and silent until something disturbs them.

During the game, you will find some of these Villages of Doom. You will have to be very careful when encountering them. Destroying them will cause thousands of infected to leave their nests. Make sure you have a big army, otherwise you will become easily overwhelmed. On the other hand, don't think that you are safe if you let some infected periodically to go out to investigate noises or smells. If your colony is near one of them, you can be sure they will find you.

At least if you manage to destroy them, you can collect a lot of resources that those poor old settlers stored with them in their bunkers. Decide for yourself and good luck!


We continue with the development of all the campaign elements. We are currently working on the trains and railway network. Let us share a design drawing of the locomotive:

Crowdfunding Campaign?

We have received many emails and comments about the possibility of backing the development of They Are Billions. Thank you very much for your support, it is very much appreciated.

We considered some months ago about launching a Kickstarter campaign for They Are Billions, but we thought it was not a good idea. First, because preparing and running a KS takes a lot of time. This prevents us from working on the game itself. Even if all goes well, it can easily take 2 months away from development. Second, we already have the funds to produce the game. OK, of course extra money would allow us to include extra features like more languages, cinematic, voices in additional languages... But the game core would still be the same. The other problem is that we risk failing and not reaching our goal. Then all of the dedicated time and effort is wasted.

So, the other option that looks more easy and reasonable is to offer the same KS rewards directly from our website. That way people wishing to back the game can do so while we focus on the development as scheduled. If all goes well, we can add those extra features to the game.

Among the rewards would be the access to the current beta to play the survival mode, private access to the development forum to give feedback and ideas, have your name in the credits, digital steampunk or zombie portraits, develop a building or unit... and much more. We will give further details on them in the next update.

What do you think? KS or direct backing from our web?

Thanks for your feedback, and 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.

Game Modes

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.

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!
