Thought this was about real crossbows ... . I remember my brother had one when we were kids, that he made in wood/metal work classes at school! Can't imagine that happening now. It was, quite literally, deadly. From short range it would fully bury a 6" bolt in a tree trunk.
I have this game, was great fun and for a game board set way above what you were used to! Good fun, probably that and Pro Action Football were my favs!
