- Citadelum Campaign IV: The Gallic Wars - 9 May 2025
Ave, Julius Caesar’s Gallic Wars (58-50 BCE) remain a pivotal chapter in Roman history, a testament to his military genius and a catalyst for profound societal change in Gaul. More than mere territorial expansion, these campaigns were a brutal yet effective engine of Romanization, laying the groundwork for centuries of Roman dominance north of the Alps. This period, meticulously documented in Caesar’s own Commentarii de Bello Gallico, which has been our main inspiration for Citadelum new content, offers invaluable insight into Roman military strategy, logistical prowess, and the complex interplay between conquest and cultural assimilation. The Gallic Wars introduces a new biome, the autumn forest, which adds more variety to the game (on top of Peninsula Italica, Africa, Hispania, Snow and Swamps biomes). Enjoy a new region map, more challenging missions and battle scenarios set in Galli…

- Citadelum (PC) Review - 17 October 2024
I’m always a fan of a good simulator, whether it’s zoos, theme parks, farms, or city-building. When the Roman city-builder Citadelum was brought to my attention, I knew I had to jump in, and I’m so glad I did. Citadelum blends strategy, simulation, and style to create an addictive experience that I can’t seem to put down. Citadelum is what happens when you blend SimCity with Age of Mythology and then ramp things up to 11. The game takes place in Rome, and you need to build a functional city for your people. However, what is deemed functional varies as your town evolves and your residents demand more. What I thought was going to be a peaceful sim game turned into a little ball of chaos when things like armies and angry Gods came into play, but more on that later. As Citadelum begins, players focus on building homes for working-class citizens known as Plebeians. The first essential struct…
- Build Rome, share Rome, play Rome. Citadelum editor. - 2 October 2024
Ave Dominus, Citadelum will be out next October 17th, and the team is working full steam ahead in the final touches, some bug fixing and polishing. We are truly excited about the final result, you will be able to play very soon on Steam. But today, I want to share something on a personal side. Since Citadelum editor was announced, I let my imagination fly with the possibilities included. It is not only about playing Campaign. Sandbox or Battle modes, but giving the player the power to create their own maps and campaigns, and share them with the community, is something huge. This is a unique opportunity to recreate some of the lesser known episodes of the roman empire, or even to change History at will. What I did, even before I had access to the game, was researching some Historical events I would love to play. I am not spoiling the surprise -you will be able to download and play it aft…
