S.L.I.M.E

 Semi Liquid Matrix Emulsion (S.L.I.M.E) did not only act as frictionless padding, allowing a Marine to wear that suit for many months if necessary, absorbing impact shocks the Arti Gravs could not handle and recycle sweat, body waste and every dead skin flake; it also acted in concert with the Auto Doc and provided medical treatment. The bio slime kept temperatures at perfect levels. It instantly sealed wounds and kept any wound trauma to the absolute minimum. The S.L.I.M.E. was more or less the same stuff Med Techs used in their Re-Gen tanks. The Blue Slime could, if necessary assist the Auto Doc and regrow limbs, bones and basically keep a Marine alive even if sixty percent of his body had been vaporized. The Blue Slime had a few other benefits as well but like the Neuro Ping, it was a thing you had to get used to.

 As soon as the Suit was ready to be sealed the slime deployed out of small openings inside the suit and then crept and crawled like a living thing, warm and moist, all over you and entered every orifice. Newbies often panicked when the slime crept into their nostrils, forced itself inside the mouth, into ears and over their faces and eyes.
