As of today, you can get Corsica & Gallia DLC for free on every platform.

Corsica & Gallia introduces two new playable maps – the titular ones – each with a unique game mechanic. They’re also both noticeably vertical!

• Corsica is a small 20 City, 8 Province map where Prefects provide bonus gold.
• Gallia is a 25 City, 10 Province map where players face the challenges of crossing the English Channel and navigating the river Sienne and securing Harbors to sail past the Mediterranean Sea!
