To get Prototype 2 model, first of all you will need a PC version of the game (script wouldn't work with Xbox-360 version). Then you will need scarface extractor (BMS script) to get models from art.rcf (art.rcf contains all models you need). And finally, if you want to load p3d files into Noesis, you should extract textures from p3d file with blender script from Szkaradek123 (just run .blend file open P3D file with it and all textures should be in the same folder in .dds format), after that open them in Noesis and you should get this.
P.S It's a little tricky process, but p3d format it's a really nightmare! I can't imagine, how Demonsangel make models work, but he did it
