Is there a special bow/sling rule in Genlab Alpha?
I don't have the English Genlab Alpha (except the campaign).
Is it that bows and slings need to be prepared before you can use them (a maneuver). If it is that rule you mean, it exists in MYZ as well (it is mentioned under reloading p85), even to the rule is described more comprehensive in Genlab Alpha. Bows and Slings are slower than scrap guns.
If it is something else, please let me know
