What is Citadelum?

Citadelum is a single-player Roman city builder where you gather resources, manage food and water, build defenses, and train legions. Across missions, you expand on a world map through trade and tactical auto-battles while completing Senate objectives and navigating the demands of the gods.

For you if...

+you enjoy planning cities around food and production chains
+you prefer goal-driven campaigns to open-ended building

Not for you if...

−you want direct control over every legion battle
−you prefer historical settings without mythological gods
