Heh..i don't think that somebody should help... Why somebody must help if they can create something that they want? Or just will complain for lack of time/skills/ideas etc.. If I will count on someone else, this project likely will never be finished...
I will make all the weapons, all the ammos, hope that also remake all efects for them (which based on moddels), and whole pickups. Insane bunch of work, but i will finish it even i'l start to die in agony tryin' to unwrap model
About textures..i know that it is styled something like NW3. But i didn't found yet other ways to get textures looks properly. I don't want to see blurred skins, where all small details (that was draw, not modelled) look like blurry spots on the model...as engine does not supports anything that will improve quality, even detail textures can be used only for level geometry

Also if to take the fact that i'm not such a good texture creator.
EDIT
The other way for me, which is less painful - totally copy original design but make it smoother and with better quality. This model will stay for other packs. Probably better to go this way...
