@Dervish Actually, I was planning to have something like that, but a bit more flexible depending on the user's customizations. But still, the really advanced stuff would be achieved later on.
@Fisticuffs Most historians agree that the Fall happened about a century ago, and since medical technology at the time was far more advanced than currently available, there are a few survivors displaced by the event. Most of them are old and bedridden however, and can barely speak. The few words gathered from them tell of a time of great prosperity, when the visions of a future many generations ago had come true.
@Corporal Lance With 11 billion active soldiers, it's impossible for everyone to have a deus-ex or Halo-style augmentation. Grunts do not have any augmentations, besides the few who must receive a cybernetic limb due to injury in combat. As soldiers climb the ranks, they are given the option to receive augmentations. And yes, a skilled engineer/specialist would be able to receive a neural uplink which would allow for them to interface with machines and such, but the functionality is limited, like activating switches and circuits and the like. Later upgrades would allow for much more advanced functionality.
