Workers keep their professions and gain experience over time. Who lives, works, recovers or dies can change what a settlement is able to support.

Rome has come to Britain.
A third-person strategy RPG where you fight, build, trade and command Rome's advance through a living Britannia that continues with or without you.
in the current developer build
integration and polish underway
solo-developed and self-funded
Single-player by design
Britannia is not a stage waiting for the player. Its workers gather, its craftspeople produce, its caravans travel and its factions pursue their own campaigns.
You experience that strategy from the ground: fighting in third person, taking your place in the invasion and deciding which settlements, people and supply lines to defend, command or disrupt.
The living world
People, resources and territory are connected. A decision made in one settlement can change the strength of another days later.
Workers keep their professions and gain experience over time. Who lives, works, recovers or dies can change what a settlement is able to support.
Resources are gathered, crafted, consumed and moved by real caravans. Protect a friendly supply line - or raid an enemy route before attacking its settlement.
Ownership, population, production and military pressure are connected. The campaign is built to leave more than a colour change on the map.
One world, two perspectives
The campaign map is built from the same landscape the player travels through. Its terrain is transformed into a restrained Roman military map, while settlements, armies and campaign information are added dynamically as Britannia changes.

Steam Next Fest · October 19, 2026
The free demo arrives October 19, 2026 for Steam Next Fest, offering a first look at the combat, settlement and living-world foundations.
Enter the invasion from a third-person perspective.
See people, resources and settlements acting as connected systems.
Experience the foundations of a campaign built around lasting consequences.
One settlement, two scales
Settlements are simulated at campaign scale, but the player inhabits them from an over-the-shoulder perspective. What changes in the economy becomes visible in the street.


Work in progress / Visuals subject to changeField report / Current build
The core simulation is playable and the current developer build contains roughly ten hours of gameplay. Development is focused on integration, performance, presentation, balance and continued stability testing.
The developer
I'm Zeno Ferenczi, the solo developer behind Invasion of Britannia.
I have independently funded and built the project for four years, personally writing nearly all of its code. The goal has always been an ambitious single-player world where the player is part of a larger system, not the switch that turns it on.
Hearth & History Games is the home for that work: historically grounded games built around the people, economies and decisions that make a world feel alive.

If this is the kind of single-player world you want to see, wishlisting it on Steam is the most direct way to support its development right now.
The final Steam link will replace this launch marker as soon as the store page is public.
