Custom worlds in Space Engineers are pre-designed planets or moons with unique characteristics and challenges provided by the game developers. These custom worlds offer players ready-made environments to explore, build, and engage in specific gameplay experiences. They are an excellent way for players to dive into exciting challenges or quickly start a new adventure without creating a world from scratch, adding variety and convenience to the Space Engineers experience.
