make more ways to counter it than the port emp and emp grenades
Other than EMP nades, portable EMP and keypad crackers, the nano suit (hacking ability), combat drone and K398 electric round can also all open the forcefield for differing amounts of time as well (I believe K398 electric rounds will hold it open for the longest amount of time and the portable EMP holds it open for the shortest amount of time).
