Undead Horde 2: Necropolis

In order to complete this you will need to rebuild every single building in the Necropolis. This is kind of misleading because one of these is not a building. You will unlock it after beating the game.

You need to upgrade all 4 summoning buildings. Spirit Hall, Corpse Hall, Animal Hall, and Skeleton Hall. You also need to fully upgrade the trader's cart, the rune hall, and the Senate building located north of Death.

All of the rest of the buildings will rebuild as you complete the game. You'll need to fully take over most of the 48 zones. Not all of them will give you a new commoner but each commoner and each bigger soul will rebuild 1 home in order to live in.

Commoners are acquired by killing every single building and enemy in a zone. Once you have taken it over the lighting will become dull and most of the time a commoner soul jar will drop.

The bigger soul jars are all found while progressing through the game. As long as you complete all question marks on each map you will get all the jars assuming you didn't forget to pick one up.
