Final thoughts. Playing this way is quite slow and it involves a bit of work. But the slow pace and effort put into it means you really want to survive, which affects your decision making and I find this quite immersive. Now, if only we had a proper U-boat simulation that would allow for this type of play. We can only dream.
Played with TWoS 2.2.24. Made possible by Vecko and all other modders involved in making this game playable.
Edit: I think the KTB pages are just about clear enough to be readable. If not let me know.
