Cerberus: Rampart Mech

Though its initial invasion of Omega was successful, Cerberus was soon faced with the problem of controlling the station's large and often lawless population. An initial solution was to establish detainment areas bordered with impassable force fields, believed to be sheets of plasma suspended in a magnetic field. As Cerberus tightened its control of the station, units that could pass freely through the force fields to police the populace became necessary, leading Cerberus engineers to recover LOKI security mechs from the remaining Eclipse mercenary chapters. When upgraded with Cerberus's proprietary mini-fabrication technology, shielding recovered from Omega' element zero processing plants, and additional ablative armor, the result was the Rampart mech, a flexible combat unit designed for control and intimidation of Omega's inhabitants.

Rampart mechs can seek out targets or troublemakers anywhere on Omega, even lower industrial areas where radiation can be intense. It is fitted with infrasound and scent markers that are "fight or flight" triggers for several species and are intended to subdue or disperse a crowd. When necessary, Rampart mechs can channel all available power into generating a high-intensity shield that defends against hacking or biotic attacks and weapons fire, protecting the Rampart until reinforcements arrive. For combat, most Rampart mechs are equipped with a standard issue shotgun; if damaged beyond repair, the Rampart mech destroys the shotgun's aluminium-alloy heat-dispersal sinks, coating any nearby assailants in red-hot residue that burns through armor.

In extreme situations, the Rampart mech overclocks into a "hunter-killer" mode, diverting power from its unique shields to single-mindedly destroy its target. In this mode, the Rampart mech moves faster, attacking with a flash-forged omni-blade that targets unprotected nerve clusters and immobilizes the luckless target. The Rampart also channels excess heat through the dispersal sinks, visible burning off material to create an intimidating display as it advances.
