Impetus is a set of wargame rules that aims to simulate battles with toy soldiers in the ancient, medieval and renaissance period.
Basic Impetus is a free, simplified, version of those rules. The aim of Basic Impetus is to accompany you on your first steps towards the world of Impetus, giving you a chance to play immediately with a smaller number of miniatures.
Being just a "taste" of the full rules we have left out a lot of the elements that are the fundamental characteristics of the original rules, to which you are referred for a more structured and exciting game.
