As you input the reboot codes you hear the building begin to hum. A loud thunk followed by a low rumbling echoes as the main generators kick back on. The lights ignite slowly, flickering to a steady glow. A wave of relief floods over you. This is the first step to making it out of here. The release doesn’t last long as you feel the ground gently shake. You hunker down behind the terminal and listen. Thud… Thud… Thud… the sounds grow louder. Something was drawn by the sound of the generators, and it’s big.
