Evaluation
They Are Billions launched into version 1.0 on June 18, 2019, graduating from Early Access with the full "The New Empire" campaign. The game has received post-launch patches and feature updates since then.
The most recent developer communication is a news post from January 22, 2026 [NEWS-1], announcing the Nintendo Switch 2 release. Within that same post, Numantian Games explicitly states: "we're also exploring how to expand both the game and potential sequels or DLCs." The post also notes that there are "other changes in the pipeline" for the existing PC game that they plan to roll out gradually. Additionally, the developer mentions working on a project set in the They Are Billions universe (described as not a video game), promising more details soon.
This January 22, 2026 statement is a clear and recent signal that the developer has not concluded content work on the game — expansion of the game through new content or DLC is actively being considered. The only DLC currently listed on the store is the Soundtrack & Art Book, which shipped on launch day in 2019. No specific new DLC has been formally announced or listed as unreleased, but the developer's own words from January 2026 establish that future content additions are under active exploration.
As of today, October 8, 2026, the last developer communication was on January 22, 2026 — approximately 8.5 months ago. This is a notable gap, but given the developer's explicit statement about content being explored and changes in the pipeline, the silence alone does not override that direct communication. There is no developer statement indicating the game is complete or that no further content will come.

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.
Lead the campaign under the orders of Quintus Crane, ruler of the New Empire, and reconquer the lands devastated by the infected.
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.
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 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!
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!
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!
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.
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!
