I'm trying to sort out this issue. I cannot find anything written as to how far a perimeter weapon, with the Boost trait, can move towards it's target...specifically Madtraps. The rules state that the weapon must move until it enters contact with its target. However, there are no movement ratings for these deployables. Does that mean it will instantly move 8" if the target is just inside its ZoC?
If the target is inside ZoC, if the MadTrap can physically(*) reach it, it will. (*) the only exception is if the target is in a fully enclosed and sealed space.
