I just spent about 30 minutes trying to figure out how I would get out of that Armored M&M. I doubt egress is something which can be done alone while the suit is upright. You could probably get in/out if it were on its back or front, but then there would be some interesting flexing rocking to get back upright. I bet under one of those flaps is a set of rings hooked to his inner suit. A derrick/hoist would then be used like for a deep sea diver hard-suit. The inner suit has catheter interfaces in the proper places and then a consolidated jack that sits at the cossix to plug you into the outer shell and activate the beast.
