From the publisher's website:
A quick and easy campaign game for the Crusades period in the Byzantine Empire, including map, counters, and miniatures interface for our "Ironbow" rules.
In fact, the game is leader driven- good leaders get things done, while poor ones are a hindrance. Counters representing every troop type are here, including Turkish Ghulam heavy cavalry, Turkomen horse archers, light and heavy infantry, Byzantine Cataphracts, Norman and Varangian mercenaries, Petchenegs, everyone. It comes with a battle board so you don't have to stop the game for every battle if you don't want to, but the troops convert directly into "Ironbow" units for those of you who want to play miniatures.
This is a web-published game that is FREE to download and play.
