I know I sound like a broken record, but Apollo's free clothing pack can be adapted to a very decent Sci-Fi uniform. I'll find Anton's example and post it here.

Armour would be great, and it wouldn't be too hard to at least adapt a chest plate from the default Vest. There are armour morphs included. All you'd need is a decent displacement map for fine detailing.

Carodan has a great Alien character, but unfortunatley it requires the Cole morph pack.

If we can hit that bullseye, the rest of the dominos will fall like a house of cards...checkmate!
