Worlds Adrift is a massively multiplayer sandbox video game, set in a vast universe that is permanently changed by players' actions. Developed and published by Bossa Studios, the game was released on PC through Steam in mid-July 2018.
Players can explore the game's vast open world of floating islands, where all in-game objects have their own weight and real-time physics. Worlds Adrift allows the player to harvest resources and free-build an airship of any size and shape to traverse the world. Due to the game's focus on physics, features of the ship, such as the number and placement of various propulsion mechanisms, will have an effect on the ship's handling, fuel consumption and speed.
The game's plot is fragmented and incomplete, and is learned from scanning various in-game ruins. The game hints that the floating islands distributed throughout the game were once part of a planetary crust, but a cataclysm shattered the planet, forming the islands floating through the atmosphere. The islands float due to "Atlas Cores" that are embedded in the islands' impenetrable rock. A previous race that built the various in-game ruins is hinted at, but there is not contact between the players and their predecessors. The islands themselves are created by players in an external software engine. Bossa Studios has hinted to a planetary core miles beneath the orbiting clouds, but the player will die before falling far enough.
