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.”

Multi-language Support: Spanish Available

First, thanks for all this wonderful support! The amount of comments, feedback, videos, twitchs... is simply amazing! There are players that are making colonies that we have never seen in our play testing. Just look this one with almost 16K colonists!

We are glad to see our game engine moving softly these huge scenes with thousands of colonists, hundred of buildings and dozens of thousands of zombies.

And here goes a quick update to inform you of the game’s development progress.

Since the release on December 12th, we have been very busy working on several important technical aspects of the game:

Solving Installation Issues

With so many players and computers, sometimes some components required by the game are not correctly installed. Therefore, some players have had problems starting the game.

DirectX: It seems the Microsoft install is not always the correctly installed version, so we have added the exact libraries to the game folder and DirectX is no longer needed.

Visual C++ Runtime 2017: The same issue here. This has been the source of a lot of problems, giving the error HRESULT: 0x8007000B (thanks, Microsoft). Now the libraries are compiled statically, so that installer is no longer needed anymore.

There are a few more technical issues that we are studying such as problems with some monitor refresh rates.

Solving Bugs and Crashes

We have fixed a lot of small bugs detected by the players and refactored some parts of the code to avoid random crashes. This new version should be the most stable one.

Multi-language Support

As They Are Billions is being played massively in all parts of the world, we have worked on implementing the multi-language support. And furthermore, we have implemented an automatic system that allows the translators to update the game with their changes very easily. So, all the languages will always be up to date and won't delay the development at all.

For notifying issues or errors in the translations please use this forum. We will create a pinned topic for every language and the translators will take of them:

Spanish Available

Spanish is the first language added and is now available on the options screen. It is available in the Version 0.5.

New Languages Coming

We expect in two or three weeks to have the next languages: Chinese (simplified and traditional), Korean, Japanese, German, French, and Russian. We are also trying to add Brazilian Portuguese, Polish and Italian.

New Content Delayed

Unfortunately, because of all the work related to the technical aspects we have delayed the development a few weeks for the new building The Tavern and the feature Challenge of the Week. But don't worry, it will be ready very soon. All the developers want to test our skills against all the players playing the same map. That is going to be very fun!

Thanks for all the support! I hope everyone has a wonderful holiday break and a happy start to 2018.

See you soon!

Survival Mode Available Now!

Greetings! Finally, They Are Billions Survival Mode is available on Steam! We know lots of people have been waiting patiently to play the game, especially the backers after we ran out beta keys. We have worked as if we were being chased by billions of zombies to launch the game much earlier than originally anticipated.

This version is now much more polished than the original. We have implemented lots of improvements suggested by the beta testers and also fixed billions of issues and bugs. This process will continue during the Early Access phase while we work on the epic Campaign Mode.

For the Backers of They Are Billions

The backing period and special editions are no longer available. Thank you so much for your support and patience. The overwhelming support for our game was so much more than we had ever dreamed of.

Your Steam key(s) are already available on your download page in Humble Store. Just use the link from the email you received as: "Your Ranger Edition is Ready.”

In January, we will start creating the special rewards for the Sniper, Lucifer, Thanatos, and Titan editions. We will contact all of you directly by email.

Last Version: V.0.4

From now on, we will announce the new versions and what's next directly on the Steam Store updates section. As many of you may already know, these were the last changes to the game:

New Mayors System
Now the colony can choose a new Mayor when the colony reaches specific population levels. There are about 100 mayors with different levels and features.

The awesome Thanatos unit is now available. He can be very narcissistic, but his rocket launcher can blow up dozens of infected in one shot!

Veteran Units
Rangers, Soldiers, and Snipers earn experience and can level up, improving their attack power and speed.

Targets Selection Priority
For the units, you can set the mode for auto-targeting enemies. Currently, it is only "The Nearest Enemy". There will be another mode, where you can set the priority "High Level Enemies first".

What's next for V0.5?

New Building: The Tavern of Lost Souls
Would you like to attract mercenaries and strange travelers of all kinds to your colony? Nothing better than offering a beer by the fireplace.

Competitive Mode: Challenge of the Week
Every week you can play a specific map that will be the same for all players. All players will compete on the same map and their score will be registered on a Leaderboard. Players will only have one chance to play the Challenge of the Week.

New Languages Coming Soon!

We have decided to anticipate the translation of They Are Billions, so the Survival Mode can be enjoyed by all the players:
- Simplified Chinese: 汉语
- German: Deutsch
- French: Français
- Spanish: Español
- Russian: Pусский
- Polish: Polski
- Italian: Italiano
- Japanese: 日本
- Korean: 한국어

The Campaign

Don't forget that the main mode of They Are Billions is the Campaign. Though the Survival Mode launch has taken us a lot of time, the development of the campaign is a bit delayed but don't worry, it is going to be like a whole new game with a great story, characters, missions, and lots of new features like the steam trains, the old fortresses, the infected mutant... We expect that it will have about 40-50 hours of gameplay. And of course, it will be included for free for all the Backers and Early Access buyers.
We will talk about the campaign in the next updates!

Thanks for your Review

As you know, reviews on Steam are more important than ever. If you are enjoying the Survival Mode, please consider writing a review. The game is just in an early access phase, so we need all of your support to continue developing and improving the game. Thank you very much in advance for your time!

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.
