Congratulations for your promotion, Praetor! Now that you well weathered governor, I want you to overcome this next challenge. Build a medium city in the dangerous African desert. This province has small water supplies but there is still some fertile land, and the rocks are suitable for mining iron. The iron is very important for your city’s survival since the main Carthaginian strike force is heading through the valley. Forge weapons, and lots of them. You are going to need them.
In addition to fending off the Carthaginian invaders, I want you to build a prosperous city and commence trade with the rest of the empire, although the clear passage of the trade routes to this distant province depends greatly on the weather. I hope you can bring life to this valley of death, after slaying the intruders of course!
TL;DR:
Standard C3 style mission with heavy invasions
Sparse water supplies
Notes: Doable without exploits (Multiple barracks / Aqueduct-road).
