How is it handled mechanically when during combat (so Tactical time), a character wishes to, say, attack the next character through a door? They lie in wait for that next person to walk through.
There's no "Hold Action" action or "Overwatch" action, and I can't find anything in the system to address this. Since there's no way to act in the middle of another character's turn (with the exception of 2 Threats being spent to provide a foe an immediate free maneuver), the target could come through that door and continue clean out of that room without the attack ever taking place.
