A game from the warhammer series.

I played on the first Sonya, there was no need to build anything, they gave a detachment of infantry and archers at the first level. They fought with the undead, then which path you choose, heavy cavalry to the right, gnomes to the left. So the troops and collected. I remember the level where they gave us a mortar and, being on a hill, destroyed entire regiments of the undead. Is there anything similar on the PC besides the Praetorians?
