The Weight Bearing conformal external assistance system (“负重者(Weight Bearing)”紧凑型外力辅助系统) is an exoskeleton system developed after 2012 by the United Nations Relic Science Agency to help in the exploration of relics site.
The primary objective of the Weight Bearing system was to develop an exoskeleton of minimal encumbrance to protect human operators from Collapse Fluid radiations when exploring relics site. The system was also outfitted with many equipment mounting points to make it highly modular for engineering, police and military purposes.
Weight Bearing was critical to the exploration of the main Antarctic relics site and the foundation of Hollow City after 2023. The Weight Bearing systems Mark 1 and 2 became the base for the Assault Artillery combat platforms AA-01 and AA-03, but after World War Three broke out, since they were not developed for combat, their downsides spurred the development of the AAX generation.
