Continuing the discussion from "Good morning Commander. We need you.":
The Augment is my stand-in for what is communicating to the player. It’s your standard Cortana/Navi little buddy thing, except it’s also like the shoulder eggs in Phantasy Star Online (haha, I can’t for the world remember what they are called, but that’s enough to figure it out ), where it is part of a system that interacts with the Legacy system. It’s like an AI that’s in your brain, serving as a digital familiar.
Which means of course we can upgrade it!
The Augment, or TA, can be renamed by the player, but we don’t care what it is called, it’s never referenced publicly.
