Since my desktop is capable of rendering in full Ultra mode, I thought I'd go in and find EVERYTHING in the new set and display it.
Here's the parameters of this shoot:
All Graphics set on high end Ultra so as to display the maximum amount of detail (and boy is there a LOT of detail!).
I used the Praetorian Character create menu so as to accentuate that sort of "brassy" look. The costumes are all set with two main colors. Nothing complicated. The colors are a deep brown and a gold. Some pieces were colored individually, but most were just fine with the default "set to all" switch on. All body proportions are set to defaults. I used "Male" and "Female". With the assumption that "Huge" would be a duplicate of "Male" I omitted taking shots of that.
There is "Classic Steampunk" and "Victorian Steampunk" as a theme. There was nothing in the way of a set theme set into the costume generator as a default. So I went menu hunting. I'm 99% certain I found everything.
I've taken shots of each as it's own set. Either all "Classic Steampunk" or all "Victorian Steampunk". No mixing of the two. This is only to show off the set pieces themselves. (Though obviously mixing of elements would create some even niftier outfits, that's not the point of this shoot.
Backbacks and Wings are displayed on the male characters. But rest assured, they do work on the female models as well. I just omitted them for clarity.
There are no "Steampunk" Blade sets. And no powers that have different effects based on Steampunk. The only powers that have skins for Steampunk are the Assault Rifle and Dual Pistols. So they are displayed here.
There are two different Auras. "Clunker" and "Victorian Effects". The clunker you've already seen in the trailer. the Victorian you've probably seen if you go to the linked forums above.
There are slightly more costume options than what's shown here. There are a couple of alternate coat options for the Male Victorian and a couple of different belt options for the Female Classic Steampunk. But what you see here is at almost everything. If it's not shown, it either doesn't exist or there are only a couple of variants of the piece to show anyway.
The last Costume set I was taking shots of was the Female Victorian. Partway through, something went wonky with my snip tool and I could only get an all black screen. But that's ok, since I was meaning to take some shots of emotes and such anyway. So I made the actual character and set her into Mercy Island for the emote shots.
There are three Steampunk Emotes: "Inspiration" (Which I tend to call "Eureka"), "Hot Temper" (stomping the ground, steam coming out of ears) and "Steam Whistle", which is exactly as advertised. Heh.
So - Voila:
