Update 1.1.1: Improvements to Camps, Raids and Campaigns
Update 1.1.1 for Summa Expeditionis is now available. Many of the changes in this release started with your reports: camps stockpiling gravel while running out of stone, looted…




Summa Expeditionis is a colony sim and base building game set in ancient Roman Empire. Follow the career of a Roman soldier from Legionnaire to Centurion. Build and manage your camp, recruit more soldiers and face the barbarians for the glory of Rome.
You are a Roman legionary sent to the edge of the Empire. In the wild north of Hispania, far from the safety of Rome, your mission is simple: establish a foothold, secure the territory, and survive whatever the frontier throws at you.
Start with a small expedition camp and transform it into a thriving Roman stronghold. Gather resources, construct fortifications, recruit and manage your soldiers, and lead your people through a harsh and unpredictable land. As your influence grows, so will your responsibilities... and your path from common legionary to respected centurion.
Construct barracks, workshops, and defenses to turn a small expedition into a thriving frontier camp.
Assign soldiers to gather resources, craft equipment, and defend your settlement.
Face hostile tribes, harsh conditions, and the dangers of unexplored lands.
Grow from a lone legionary into a respected commander of Rome’s expedition.
Summa Expeditionis is more than a game: it’s a test of wit, courage, and leadership. Will you answer Rome’s call?
💥 Play now in Early Access and help shape the ultimate Roman Empire experience!
