A SHIPWORLD file contains information about the spaceship of a player in Starbound, a 2D space exploration game. It stores ship information, such as the race of the ship, object placement location, storyline progress, and completed missions.

SHIPWORLD files are primarily used by the Starbound game to load saved ship information. However, they can also be opened by starcheat, a Starbound save editor. SHIPWORLD files can be found in the "player" folder in the "Starbound" folder. For example if you purchased Starbound through Steam, the PLAYER files are stored in the following location in Windows: C:/Program Files/Steam/SteamApps/common/Starbound/player
