No burst of fire from inside, so I spin around the frame in a crouch, scanning with eyes and with the barrel of my weapon. It’s pitch-black inside, and the light from outside is enough to illuminate only the first half-dozen meters of the hallway that stretches away from me. What the frag happened to the lights? Did some of our troops blow the power, or have the defenders decided that darkness is more a disadvantage to us than for them? Cautiously I move forward again.
