The work on the MIS series did not stop even during the development of the Artifact Hunter. It continued in the background but did not cease. Thanks to significant technological advancements in the Zones research and extensive experience in creating such suits, Research Institute 7 developed an almost perfect scientific suit. It is intended for research in the Zone. Rumor has it that the protection elements for Atlas, as well as for the 85D, were found rather than created from scratch. According to some particularly talkative stalkers, because no one completely understands how they work, the suit ended up with flaws.
