On page 11 it says that Art in a PF which are to shoot out must be in a tower.
On page 12 the costing example strongly suggests towers are square.
On page 34 it says that any edge of an element in a PF tower can be the shooting edge, and that an element is a valid target if any part of it is visible within half a base width of straight ahead of any part of the shooting edge.
Put all this together, and it appears that elements approaching from a 45 degree angle towards a tower's corner are pretty much untouchable by shooting until they come within half a base width of the tower, at which point they're only one move away from contacting.
Something about that doesn't seem right.
Have I got the rules right, or is there something I'm missing?
