Are you looking for more armor sets? Imperial & Civilian Pilot Sets were added to S-1A0 after the patch. Some players are still complaining about the customization of the armor sets in the game. Personally, I think the Imperial sets look pretty good compared to some of the other sets. What do you think?
There is also some discussion on the official forums about where and how you get Imperial and Civilian Pilot Sets in the game.
