I think that bethesda should add traps that you could craft and place your self (eg1. trip wires, hidden mines and pressure plates...) and combine traps together (eg2. is that you could place a trip wire across a door that activates a shotgun ,missle launcher ,grenade rifle or to keep a door shut). I've also thought that you could create trip wires out of 2 scrap metal and 1 ripped out wires from demolished walls.
