Conquer Britannia and turn it into a bustling city of prestige and culture despite of the difficulties.
Difficulty: hard
Begin small and focus mostly on income and military.
It may take up to 20 years to finish the scenario.
PS: I don’t know how to get the cohorts to deploy and return to forts on their own. You have to do it yourself. I’d appreciate it if someone could tell me how to fix this.
