Aug eyes no pain

Darkness descended, lit only by pulses of light from passing warning
lamps as they flashed by. In the strobing, staccato glow, Jensen and his
attacker twisted and fought in dangerously close quarters. The wide dagger
blade hummed as it cut through the air toward his throat time and time
again. With each swing, Jensen tried to extend away, but there was nowhere
to retreat to. Instead he went on the offensive, bringing down the butt of the
pistol on the brow of the helmet. He smashed one of the quad-eyes and the
attacker flinched; Jensen guessed they were neural-jacked straight into the
overlapping mech-optics, and although there would be no pain effect, it was
hard for anyone to have their eye – real or not – crushed and not shrink
from it, even for a moment.
