Black lines are impassible walls. The defending team may enter the green "archery towers" freely and exit freely. Anyone standing up in a tower may fire projectiles out of them(and threw walls, as they are "over" the wall) and may also be fired upon with projectiles, and are within line-of-sight of verbals. Anyone crouched, sitting down, or kneeling in a tower may not be seen or affected from outside the tower, although "Tracking" may be used by a member of the other team to enter the tower and attack anyone inside.
