"Starbound is an indie game produced by the UK-based independent game studio Chucklefish Ltd. Starbound takes place in a two-dimensional, procedurally generated universe which the player will explore in order to obtain new weapons, armour, and miscellaneous items. Starbound entered beta testing on December 4, 2013 for Microsoft Windows, OS X and Linux.
Starbound begins with the player inside a spacecraft fleeing their homeworld, each race with their own unique reasons for leaving. With nothing to guide it, the shuttle shoots into space without direction, becoming hopelessly lost in a sea of stars. As luck would have it, the space shuttle touches down on a habitable planet and an adventure begins that takes the player hurtling across the universe. Starbound contains both quests and story driven missions, buried inside its vast sandbox universe."
