It makes use of zones. These could be a map but it doesn’t have to be.
Zones are very flexible, it could be a small as your left & right hands and body if running a duel all the way up to sections of a city for Espionage/Warfare. (If you look at my thread on Espionage/Warfare conflict you can see the map I used)
For most skirmishes zones will be a series of rooms or similar. If you are in the same zone you can engage in melee, if you are further away you have to rely on Ranged weapons or psychological attacks.
