The mEPS MK1 was the first prototype of the mEPS line of Active PPE Exosuits. It never saw adoption outside a small select test groups. It was plagued with mechanical and electrical issues as well as a general low reliability.

It featured a small power pack and could power the exosuit for a mere three hours before running out of charge at 80% load. Furthermore, it featured a 1.3 ton lift capacity sustained and a 2.7 ton lift for short duration.
However the MK1 lacked any sort of protective lining for the user meaning that it saw frequent user injury in the pinch points of the suit and meany more close calls.

While the mEPS MK1 never saw widespread adoption, and it remains rather infamous it did lay the groundwork for future mEPS.

Status: As of now the mEPS MK1 is fully deprecated and sees no use in any capacity.
