A early defense technology from Rodent Industries that has seldom been improved on due to its mimicking natural processes that have evolved over centuries. It was accidentally discovered in the lab when a batch of study rats developed some very pernicious mites destroying the skin tissues at a very rapid rate. These mites were genetically patterned and then reproduced with nano technology. It is not lethal in-itself but is devastating to any sort of protective suit.
This defence can only be neutralized by a immunio-frequency radionic chip that is specifically programed to the individual using it.
This product is recommended only for users of the Hermit grade.
