Just found a couple of people running around on New Romulus with the new outfit, like to know how they did it. I checked the tailor options and there was nothing for the Elite or Elite Commander, and no way people got the Adapted set yet.
The Black MACO outfit that people are using is the Photonic Tactical Boff from the Lobi Store for 300 Lobi crystals. These Boffs use the same type of armor as the MACO armor from the new limited fleet project except they have a helmet and is black. Players can't wear this uniform yet.
