Well, you could use a timer linked up to ALL of the dispensers, and set the timer to shoot every 1 second, and then get a pressure plate system up and a NOT gate linked to the pressure plates, so when somebody steps on a pressure plate, the NOT gate will deactivate, turning on the timer and launching this death rally. But of course, on my computer things don't work out and it requires pressure plates DIRECTLY linked up to a dispenser, not the pressure plate to NOT gate to timer system. Of course, this may work on your computers but it probably won't work on mine. On the other hand, you COULD try to make a forcefield that covers like a 1500 block radius or something like that, deactivate from the inside, yeah. Just make a forcefield the size of your base.
