We built the gate in Nevada, on an army base. When we turned it on, it took almost four hours to stabilize. By the time we could make out any detail they were already trying to come through. They built an enclosure around it within a day. They tried sending a robot through, but it bounced right off. So did those energy pulses. By the time they thought of a laser we had the mirrors up. I don’t know why nothing solid’s worked… it’s supposed to be a gate. But from the looks of their weapons I’m glad it’s not.
