No, that is unknown. Its relationship to MJOLNIR [GEN2] is also unknown. I suspect that it is sparsely deployed, or only ever reached the testing phase due to the need for mass produced affordable MJOLNIR armor systems. It was the HRUNTING/YGGDRASIL MK-I. And no, no more were ever made. It was a prototype for a reason. Such a suit was never attempted to be designed again due to the severe safety hazards of operation. However, the HRUNTING/YGGDRASIL armor systems did not end there. While extremely costly, they seem to have made a breakthrough with the HRUNTING/YGGDRASIL MARK IX "Mantis" armor system. Another thing to note is that the Prototype itself, despite never reaching production phased, and was destroyed, did influence the development of MJOLNIR.
