Ok, given the creativity and imagination of the guys here that make our game today so much more with mods than the devs managed, lets have a bit of fun and think up some funny mods that you're probably NOT likely to see in our beloved game.....
I'll do a few:
'Floating poo, used condoms and other sewage debris mod v0.9beta' - That's right, the English Channel has never been so real.
'Silent Munter GUI mod' - A new GUI adorned with ugly women. Viewer discretion advised.
'Back to nature mega mod' - Be a whale, or a dolphin, or a fish, or a shark and fight for your place on the foodchain, dodging torpedo's and submarines as you go (multiplayer compatible).
'Pass the depth charge sidegame' - Using the crew models, gather on the dock and pass the ash can around, don't be the one holding it when it detonates as there'll be trouble, and blood, and carnage, and it means you lost the game.
I could go on but, over to you guys and your twisted minds......
