Update #7: Build your colony!

Today we are going to talk about building and managing the colony. Managing the colony is one of the most important aspects of They Are Billions. What you build and where is key for the success of the colony. So let's talk about the main aspects of city-building in They Are Billions.

Where to build...

When you start a game, you will have the Command Center already built. This is the main building of the colony. You can start building structures on the available free cells surrounding it. Most buildings cannot be next to other buildings as you need to have at least one cell in between. But there are special rules for different buildings. For example, colonist dwellings can be placed next to each other up to two rows. Tesla Towers, walls, traps, towers can be built next to any other building. In contrast, some buildings must be separated by a specific distance to properly operate like Mills, Warehouses, Markets, Banks...

A very important aspect of the game is that you can only build structures inside the energy coverage of the colony. The Command Center has energy coverage radius of 10 cells. If you wish to expand the colony you will have to build Tesla Towers to extend the available area. If the energy network is broken because a Tesla Tower has been destroyed or infected, the buildings affected will be disabled until the energy supply is restored.

Because of the threat of the infected, you have to be very clever on where you place your structures. You have to factor in the environment geography and the energy coverage of your colony. Sometimes you won't even have physical space for a specific big building, so you have to expand the colony further than you'd like. That is often very risky and dangerous... Don't waste space! And at the same time, you have to take into account to have fast access to roads for your soldiers, otherwise, when you need them to defend the colony, they will waste a lot of precious time running in a maze of buildings.

Storable Resources

These type of resources can be produced or collected and then stored in the colony. They are five: gold, wood, stone, iron, and oil. These resources are produced daily, working time of eight hours (in game time). They are spent when you build or repair structures, train soldiers... Also, most of the buildings have a permanent gold cost (the salary of the workers inside). Some of them, like the Power Plant, require a permanent input of wood and stone to produce energy.

Gold is mostly generated by the colonists. The more colonists in the colony, the more gold that will be produced. Better houses generate more gold. Also, some special buildings like the Command Center, Bank, Market or even quarries with access to gold deposits can generate gold too.

Wood is produced by the Sawmills while stone and iron are produced by the Quarry. These buildings have a collection radius and can only obtain resources from the cells inside that radius. For example, the Sawmill gets wood from surrounding trees. The more trees inside its radius, the more wood it will produce. When you build this type of structures, a message will appear, telling what the production value will be if you build it in that place. Two structures cannot be built too close that their gathering radius is overlapped.

Oil is a special and very valuable resource that can only be obtained by placing Oil Platforms over oil fields. However, these usually are very scarce and often very far away from the colony.

Resource sources don't ever end, provided that they have their needs covered (workers, salaries, energy...), the building will produce resources forever. BUT the colony has a limit to store resources. That limit depends on the number of warehouses you have built. The excess resources will be wasted if the storage limit has been reached unless you have built a Market. In that case, excess resources will be automatically sold, providing the colony extra income in gold.

Supply Resources

These resources are an integral part of your colony:
- Workers: Most buildings need workers to operate. The more complex the building, the more workers it will need. Also, you need workers to train soldiers for your army. Workers are provided by the colonist dwellings.
- Food: Every colonist will consume one food unit. Also, some soldiers need extra food units. You cannot build houses or train soldiers if you don't have the available food required. Food can be produced by some buildings like the Hunter Cottage, the Fisherman cottage, Farms... In the same way as the resources buildings, they have a production radius that will determine how much food they will produce depending on the surrounding environment. The Hunter Cottage prefer woods and fields to find food. The Fisherman Cottage needs sea/rivers. Farms prefer grassy fields.
- Energy: Most buildings require energy to work. Build Mills or Power Plants to provide energy for the colony. To extend the coverage reach of energy to your colony, build Tesla Towers.

Army Buildings

There are two buildings to train/create units for your army: the Soldier Center and the Engineering Center. Every unit takes some time to train. You can create as many of these buildings as you need.

Researching Buildings

In the beginning, you will only have some basic structures and units available to you. There are three special buildings that let you research new units and structures. They are the Wood Workshop, the Stone Workshop, and the Foundry. They are very expensive to build, and every research has a high cost. However, through all of your research, you will be able to evolve the colony with more sophisticated buildings and units. Deciding which new technology to research is key for the colony’s progression.

Other Special Buildings

There are special buildings with special features that affect the surrounding buildings. For example, the Market reduces the food consumed by the nearby colonist dwellings. The Warehouse improves the resource production in all surrounding resource producing buildings. The Banks increase the gold collected from the nearby colonists.

The Three Pillars of They Are Billions

As you can see, there a lot of decisions to make when building a successful colony. There are three main pillars in the game that must be well balanced because they are equally important:
- The Colony Management: Economy, resources, colonists...
- The Colony Defense: See the last update :)
- The Colony Army: The colony cannot progress without an army that can clear the infected from the areas that you wish to colonize, for getting resources, reaching better defense environments or just to have enough space to expand the colony.

This has been a long post, but don't be afraid of the complexity of the game. Indeed when you play, everything feels very natural and intuitive, and most importantly - fun! :)

Beta Incoming

We are still polishing the beta and solving some nasty bugs. We have finally found a mysterious bug that can crash the game after an hour of playing. It seems the culprit is the sound library... Several days of development has been lost because of that bug, but it is OK because that is part of game development. We expect the next update for the end of October to be about the beta release and the gameplay video - cross your fingers!

See you soon!

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!

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!
