This Campaign has Normans playable only and the unplayable is Papal States, Scotland and Saxons
next release would be all factions and maybe a Grand Campaign in the Prolouge Map
(the map is not mine is belongs to the original Medieval II Total War Map)
NOTE: This does replace 2 files in the original Game
Installation:
1. Download (it's a .rar)
2. extract to C:\Program Files (x86)\Steam\steamapps\common\Medieval II Total War or wherever it is installed
