As far as mods go, TWoS will come with some additional mods you can install/uninstall via JSGME. I uninstalled Real Navigation and Encrypted BDU messages myself (Although I would recommend using the Enigma machine at least once or twice just to experience it. For whatever reason I still occasionally get encrypted messages and had a blast learning to use the machine to decrypt them. Gave me a new appreciation for the minds that came up with that process of encryption.)

I also installed a mod called critical hits for torpedoes. Other than that, TWoS seems to be pretty much a one-stop shop to making Silent hunter 5 the game it SHOULD have been on release all those years ago.
