how do you get extra armor?

[Ingeras Kurai]

for the gold edition it lists Hydraulic Suite and Cyborg Battlearmor but i've researched everything and still can't find them, sitting at end of game with particle weapons. what did i miss?

Don't quote me on this, but I think that I read somewhere that those are dlc.

Yeah, I couldn't get those back then as well. How do we get those?
