A century prior to the start of the game, the Kushan, humanoid inhabitants of the desert planet Kharak, discovered a spaceship buried in the sands, which holds a stone map marking Kharak and another planet across the galaxy labelled "Hiigara", meaning "home". The discovery united the clans of Kharak, who had previously determined that they were not indigenous to the planet. Together, they spent the next century developing and building a giant mothership that would carry 600,000 people to Hiigara, with neuroscientist Karan S'jet neurally wired into the ship as Fleet Command to replace an unsustainably large crew. The game opens with the maiden voyage of the mothership, testing the hyperspace drive which brings the fleet to a new destination by faster than light travel. Instead of the support ship that was expected to be there, the mothership finds a hostile alien carrier.
Homeworld is a real-time strategy game set in space. Gameplay, as in most real-time strategy titles, is focused on gathering resources, building military forces, and using them to destroy enemy forces and accomplish an objective. The game includes both single-player and multiplayer modes; the single-player mode consists of one story-driven campaign, broken up into levels. In each level, the player has an objective to accomplish before they can end the level, though the ultimate objective of the mission can change as the level's story unfolds. Between each of the 16 levels is a hand-drawn, black-and-white cutscene with narrative voiceovers.
