What era of the middle ages is the game set in? We unfortunately know very little about anything to do with combat styles for the early (500-1066) and high (1067-1300) middle ages. We can only look at their armament, Armour and sometimes other primary sources to get an idea of how a weapon was used. Around about 1300 AD saw the first medieval 'fechtbuch', or 'combat manual' being written. From then on they occur quite frequently, up until modern day, with the German and Italian schools being the most predominant, but with surviving texts from across Western-Europe. Due to the rise in popularity of HEMA and other European martial arts there has been a lot of debate surrounding them in the last decade or so. Here is an extensive list of some combat manuals hosted by one such society, with background for many of them. Hope this will help.
