Built as a Tier 2 robot for protection of LENUA Robotics facilities and patrolling both protected areas and new colonies, the 'Patroller' variant is fitted with a Tier 2 AI system as well as a standard issue LENUA bullpup carbine. The more advanced 'Stalker' variant was built with a Tier 3 level AI system, special camouflage and the same standard issue LENUA bullpup carbine with advanced silencing capabilities. It also has its own lighting for low-light level missions. 'Stalkers' can be identified by the red-black paint job and orange glowing parts. 'Stalker' type robots are often used by LENUA to undergo secret operations such as assassinations, industrial sabotage and other missions in dangerous areas where LENUA does not want to be seen. Modified Patrollers were also used later in the LTA (Lenua Terrestrial Army) as well as in an industrial setting as Utility workers.
