A face no mother could love

All of John’s men were dead, so he hid underneath them for cover.
Strange shadows lurched along shattered walls. Something was walking towards John, but it was with a step neither robot nor man.

“The 600 series had rubber skin,” he mumbled to himself. “We spotted them easy.”
No mother could love that face, not that the thing ever had a mother.
