Well, tell ya' what, how about I do something and involve the public during pre-public release.
For these "Themed" packs, if you want to participate, both (testers and non-testers), help me out some. Make some concept art for weapons that would go for a certain theme. Maybe you guys can vote on a theme or color scheme. If you want to make concept art, PM me your pictures. On how to make the concept art, simply make a 2d side view of the weapon, and if you have anything extra to say about it, like some details not depicted well or at all in the picture, then include that in your pm. (Try to aim for a futuristic or high-tech look)
