Okay, so I may be headed for an "M" rating here... I decided to experiment with graphic representations of wounds tonight, and everything appeared OK in game. For now the wound textures will automatically appear on some of your crewmembers when your submarine is damaged. However, I may be able to link this feature to the "wounded" state for crewmembers, which would be ideal. Just three types of injuries have been made so far, but I have plans for lots more. There's basically no limit to how many different injuries you can assign to one of the body types, so I'm pretty much limited by my [sadistic] imagination. 
In between researching wounds I'm also wrestling with S3ditor. If I do manage to crack this puzzle, the results could be ... interesting. 
Of course, there will be a patch to remove this feature, rendering things kiddie friendly. If you want to kill thousands of Entente sailors without having to see a drop of blood between 1914 - 1918, that's fine with me.
Officer on the deck! Some more changes to the Officer outfits...
Sorry for multiple posts but I could not get all the images in one post.
