Colonists can still join later, of course. Starting a game with a landed ship prevents new pawns from being created at game start. Hull tiles automatically create roofs for themselves, which may cause compatibility issues with roofing mods. Placing a wall, nutrient paste dispenser, or any other building which counts as a solid wall will prevent placement of hull tiles in that area. Hull tiles can only be placed in a room fully bordered by ship parts. Put your colonists/animals in cryptosleep caskets. "Loose" pawns aboard a ship won't be saved with it (they'd die during the interstellar journey). Cryptosleep caskets can be built inside a fully sealed hull at reduced cost.

Any building or item placed atop a hull tile is saved with the ship - letting the colonists bring their favorite art, their workshop, and all the supplies the next colony might need.

SOS also includes new ship parts which allow constructing a proper interior. You can then start a new game using this ship to continue your colonists' stories on another world! Research, player faction data, and pawn relationships are all carried over. With this mod, any ship you launch is saved to a file.
