History of the Ancient Seas III: MARE NOSTRUM is the dramatic conclusion to the History of the Ancient Seas trilogy from Sound of Guns, delivering the most expansive and competitive experience yet. Set in the golden age of empire, this standalone strategy game casts 3–5 players as the leaders of great civilisations competing for dominance over the Mediterranean world.

Over centuries, the region has seen countless empires rise through trade, diplomacy, and warfare. In MARE NOSTRUM, you'll command one of five mighty powers: Rome, Carthage, Greece, Egypt, or Persia. Each faction possesses unique abilities, strengths, and divine patronage—offering deep asymmetric gameplay and new tactical challenges with every session.

To achieve dominance, you must expand your influence through conquest and commerce—sending armies and diplomats to far-flung provinces, founding colonies, and securing trade routes. Maintain the happiness, wealth, and culture of your people while balancing your military and economic agendas. Whether you build a golden age of prosperity or pursue glory through the sword, the fate of your empire is in your hands.

Gameplay is driven by the acclaimed impulse-based action cycle, where each player chooses one of eight powerful actions per round. Once an action is taken, it’s locked out for the next player—creating fierce competition, shifting priorities, and intense strategic depth. Timing and foresight are everything.

MARE NOSTRUM adds new elements to the series, including support for five players and deeply individualised powers for each civilisation. With gorgeous 3D wooden components, detailed maps, and a rich historical setting, it delivers a true empire-building experience where every decision resonates across sea and land.
