Leaving Early Access: 2026

What the developers have to say:

Why Early Access?

“Our goal through Early Access is to involve the community in the development of Summa Expeditionis. This will be a huge help in launching the best possible game.”

Approximately how long will this game be in Early Access?

“Our plan is for Early Access to last 12 months. This could change by lasting a few months less or a few months longer.”

How is the full version planned to differ from the Early Access version?

“At the moment, the first campaign and the core mechanics are close to be fully developed and launched. The complete version 1.0 will include this first campaign and all the mechanics developed and polished.”

What is the current state of the Early Access version?

“The current version includes all the core game mechanics (gathering, hunting, building, crafting, management and combat) and a complete campaign (northern Hispania).”

Will the game be priced differently during and after Early Access?

“The price of Summa Expeditionis will not change during Early Access, but will be priced higher at launch.”

How are you planning on involving the Community in your development process?

“The main channels of communication with our community will be the Steam forums and our Discord server. Beta testing of new versions will be reserved for those who actively participate in the community by providing feedback.”

About This Game

Establish Rome’s frontier in untamed barbarian territory. Build a legionary camp, command your soldiers, and carve a Roman stronghold out of the wilderness.

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.

BUILD A ROMAN CAMP

Construct barracks, workshops, and defenses to turn a small expedition into a thriving frontier camp.

COMMAND YOUR LEGIONARIES

Assign soldiers to gather resources, craft equipment, and defend your settlement.

SURVIVE THE FRONTIER

Face hostile tribes, harsh conditions, and the dangers of unexplored lands.

RISE THROUGH THE RANKS

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!
