Shop Unwrap & Texture Updates

Here is the shop unwrap, I had some major issues unwrapping the drone, the verts were crossed in the UV editor, I removed the drone and unwrapped the shop, the hologram area on the shop has been removed and instead of having the drone animate which we don't have time for the drone will be the projection of the shop: 

The rest of the textures have had updates, one of the feedback given to us when using the gatling gun was that the screws were far too big, screw size has been reduced and more have been added, black lines were added to all the textures, thicker black lines on certain areas will give it a more cel shaded feel, more grunge was added to the guns (Including drone) along with the completion of the shotgun texture, the pistol had minor additions to the grunge layer, the decals have been flipped to be the right way when put into engine:
