[Science and the world of tomorrow] Soldiers fighting in weaponized exoskeletons, how plausible is that for the future?

I was observing an acquaintance playing a video game where the combatants were cloaked in weaponized exoskeletons similar to those the ”liberated people” of the Matrix tried to defend the docks with. The exoskeletons in this video game had heavy machines guns, as well as rocket launchers, the ability to leap further and higher than natural humans, and I suspect able to run faster too, but even if they could not run, the heavy armor or Kevlar made it difficult for conventional weapons to penetrate. How plausible do you see as an evolution of warfare and who do you think will attempt to introduce it first?
