Have you considered talking to DMorgado whos working on a power armor model. The current armor seems pretty near godmode and could well be your APA Mk III. I of course do not speak on his behalf and own nothing of his(Disclaimer lol).
Crank out pictures of areas your working on or keep a blog on story elements and characters. People are more interested in product rather than ideas. Just an idea to spark interest.
Btw I just read the part about Sgt Dornan, I'd be just as happy that you just recreate the conversation from fallout 2. Theres enough epicness in that alone
Heres what i ment by digital camo http://www.dressaday.com/digital_camo.gif I dont think it should be too vibrant but pretty faded out, but that's kind of obvious in Fallout
The grey texture is pretty amazing, brown is cool too but i would prefer the grey. If it's not too much can ya make a digital camo version, i think it would fit in well with the mesh
