An obsolete android patrols a frozen industrial wasteland alone.

ECHO 4: obsolete android, faded red and tarnished chrome with visible military insignia beneath decades of scratches. Right arm replaced with jury rigged industrial hydraulic claw from three salvaged machine types. Face plate cracked diagonally revealing expressionless matte grey synthetic face  no distress, no readable emotion. Still patrolling its original war assignment. Survivor of the first machine war; carries memory of every conflict. ZONE: Dieselpunk industrial wasteland  cranes frozen mid swing, war halted construction, smashed machinery piled three stories high, hazmat salvage crews below, ash clouds blocking all natural light.
