Emperor: Rise of the Middle Kingdom Hints for PC
Also on: PlayStation 2
Tested In Campaign Mode
Get all the soldiers allowed, then Delete the Infantry base, quickly hit undo.
Your soldiers will all remain dead, but now you can add as many bases you want, of any kind.
To build an army, all you have to do is have some houses (duh!), but they only have to be common houses. Then build a fort joined with a road.
Buy or make weapons and you should have a fort of soldiers. My favourites are Infantry and Cavalry.
