shotgun: stripes/dashes on a black metal texture. silver highlights, and blue (radioactive?) shells (same ones used in the sci-fi shotgun by Pyccna)

chaingun: only some orange bands around each barrel

rocket launcher: orange stripes/bands, and the text "N00b TUBE" on the side (visible in hud). also includes modified mask to smooth out the texture. (understandable if this is not used by everyone... it doesn't really change much)

rifle: orange and black all over. made with my Custom Rifle Skin Templates resource pack. (shameless plug)

'nade launcher: darkened the grey original grey texture, added stripes on each cylinder and the barrel. brown ergonomic grip. large radioactive symbol on the front of the drum. (this thing is deadly)

pistol: brown handle with modified normal/bumpmap (very high quality, if i may say so myself). orange stripes all over the barrel. added a red mark on the sight, and a barrel hole (believe it or not, the original texture for this gun HAS NO BARREL HOLE??!)

chainsaw: blood-splattered bar and chain, dark grey engine with black and orange highlights (the ripcord handle is orange, for example). saw logo on the side.

nothing is stopping you from modifying these skins to your heart's content. add text, put the skins through filters, or paste over them with clips from the original skin. i not only am ok with this, but highly encourage people to experiment and design their own skins.
Have fun!
