Originally designed as the laboratory's primary security unit, Servo Stalker patrolled the facility's perimeter with unwavering dedication to its protective protocols. When the chemical cascade began spreading through the complex's ventilation systems, toxic vapors infiltrated its central processing core, corrupting its friend-or-foe identification systems and transforming protection subroutines into hunting algorithms. Now it stalks the fairways with mechanical precision, treating every player as a contamination breach requiring immediate neutralization.

Servo Stalker stands seven feet tall on articulated legs that move with unsettling precision despite visible chemical burns eating through its chrome plating. Neon green coolant leaks from corroded joints, leaving glowing trails that mark its patrol routes through the contaminated forest. Its optical sensors flicker between normal surveillance mode and corrupted static bursts, while internal speakers emit distorted security warnings in multiple languages. Electromagnetic pulses from its damaged power core interfere with electronic devices, creating dead zones of crackling energy wherever it roams.

Servo Stalker enforces the facility's increasingly corrupted security protocols, hunting players who venture too close to restricted laboratory zones or trigger motion sensors hidden throughout the course. Its degrading programming makes it unpredictable, sometimes ignoring obvious targets while obsessively pursuing players who unknowingly match corrupted threat profiles stored in its damaged memory banks.
