A fourth incarnation of the best (and the only) Sunless Skies mod. The mod was developed for Steam version of the game and works with GoG version. It is possible to launch the mod on Steam Deck, given your OS on it supports Net Framework 4.62+ and SSkies version is identical to one for Windows (read more on the matter in the end of description). To install the mod on Mac you will need to figure out how to install Mac version of BepInEx, which is a complicated process and I can't give any directions here.
