"Scanning armory inventory," Rogue processes as your nanobots slither across the dusty weapon racks. "Found electromagnetic shielding gear - degraded but functional. And six EMP rifles. I can rig them to blow while keeping one operational for us."
Your nanobots begin their work on the weapons when a distant mechanical whir echoes from the stairwell. The sound is getting closer, accompanied by the distinct clicking of metal on metal.
"Jack," Rogue's presence sharpens. "Something's approaching. Fast. Quadrupedal gait pattern. And... the ventilation system just activated - air's being pushed into this room."
The Squad Leader's face drains of color at the sound. "Sentinel," he breathes.
What's your next move?
